7 The first change in the data and metadata message is one of terminology. In order to foster consistency in the standard, the names and namespaces of the data and metadata message have been changed. The namespaces now have a uniform format of /data/format and /metadata/format. This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).
8
9 For data messages, since version 3.0 only the (data-)structure-specific format is maintained, the generic format being deprecated. The structure-specific data message combines the principles of the former compact and cross-sectional formats into one more generalised format. All data can be exchanged as either an un-grouped collection of observations, each specifying a full key, or it can be exchanged as data grouped into [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] with any single [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] placed at the observation level.
10
11 A base schema now imposes a strict format for the generated structure-specific schemas. This not only allows performing the required validations, but the messages will also be much simpler to process as the format will always use the same element names.
12
13 For metadata messages, since version 3.0, in opposite, only the generic format is maintained, the (metadata-)structure-specific format being deprecated.

36 //**DataSetType:**// DataSetType is the abstract type which defines the base structure for any [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] specific [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]. A derived [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] type will be created that is specific to a [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] and the details of the organisation of the data (i.e. which [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] is the observation [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]). Data is organised into either a collection of [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] (grouped observations) or a collection of un-grouped observations. The derived [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] type will restrict this choice to be either grouped or un-grouped observations. If this [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] is "AllDimensions" then the derived [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] type must consist of a collection of un-grouped observations; otherwise, the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] will contain a collection of [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] with the observations in the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] disambiguated by the specified [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the observation level. This [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] is capable of containing data (observed values) and/or documentation (data and metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values) and can be used for [[incremental updates>>doc:sdmx:Glossary 2\.1.Incremental update.WebHome]] and deletions (i.e. only the relevant updates or deletes are exchanged). It is assumed that each [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] or un-grouped observation will be distinct in its purpose. For example, if [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] contains both data and documentation, it assumed that each [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] will have a unique key. If the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] contains only data or only documentation, then it is possible that another [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]]. This base type is designed such that derived types can be processed in a generic manner; it assures that [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] specific data will have a consistent structure. The group, [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]], obs, and atts elements are unqualified, meaning that they are not qualified with a namespace in an instance. This means that in the derived [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] types, the elements will always be the same, regardless of the target namespace of the schemas which defines these derived types. This allows for consistent processing of the structure without regard to what the namespace might be for the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] specific schema.

67 |[[Annotations>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]]|AnnotationsType|[[Annotations>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]] is a reusable element the provides for a collection of [[annotations>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]]. It has been made global so that restrictions of types that extend AnnotatableType may reference it.
68 |DataProvider|DataProviderReferenceType|DataProvider contains a reference to the provider for the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]].
69 |Atts|//AttsType//|Atts contains a set of data or metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values with an [[attachment level>>doc:sdmx:Glossary 2\.1.Attachment level.WebHome]] of none (i.e. [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] (% style="color:#e74c3c" %)level(%%)) or reported against a partial set of [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values.
70 |Group|//GroupType//|Group contains a reference to a defined group in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] along with its key (if necessary) and values for the [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] which are associated with the group. An [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] is associated to a group by either an explicit group relationship or by a group attachment when the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] has a relationship with a [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] which is a member of this group.
71 |[[Series>>doc:sdmx:Glossary 2\.1.Series.WebHome]]|//SeriesType//|[[Series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] contains a collection of observations that share a common key (set of [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values). The key of a [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] is every [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] defined in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], save the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the observation level. In addition to the key and observations, the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] contains values for data and metadata [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] which have a relationship with any [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] that is part of the [[series key>>doc:sdmx:Glossary 2\.1.Series key.WebHome]], so long as the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] does not specify an attachment group or also has a relationship with the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] declared to be at the observation level.
72 |Obs|//ObsType//|Obs is an un-grouped observation. This observation has a key which is a set of values for all [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] declared in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. In addition to the key, the value of the observation can be provided along with values for all data and metadata [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] which have an association with the observation or any [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] (so long as it does not specify a group attachment).
73 |Metadata|MetadataSetType|Allows for attachment of [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] against to the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]].
74
75 //**GroupType:**// GroupType is the abstract type which defines a structure which is used to communicate [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values for a group defined in a [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. The group can consist of either a subset of the [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] defined by the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]], or an association to an attachment [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], which in turn defines key sets to which [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] can be attached. In the case that the group is based on an attachment [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]], only the identification of group is provided. It is expected that a system which is processing this will relate that identifier to the key sets defined in the [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]] and apply the values provided for the [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] appropriately. [[Data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] schemas will drive types based on this for each group defined in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. Both the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values which make up the key (if applicable) and the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values associated with the group will be represented with XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]. This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived group type will refine this structure so that the [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] are explicit. The XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be given a name based on the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]'s identifier. These XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be unqualified (meaning they do not have a namespace associated with them). The [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be required while the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be optional. To allow for generic processing, it is required that the only unqualified XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] in the derived group type be for the group [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] and data or metadata [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] declared in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. If additional [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] are required, these should be qualified with a namespace so that a generic application can easily distinguish them as not being meant to represent a [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]].

In addition to observations, values can be provided for data and metadata [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] which are associated with the [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] which make up this [[series key>>doc:sdmx:Glossary 2\.1.Series key.WebHome]] (so long as the [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] do not specify a group attachment or also have a relationship with the observation [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]). It is possible for the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] to contain only observations or only [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values, or both. [[Data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] schemas will derive a type based on this that is specific to the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] and the variation of the format being expressed in the schema. Both the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values which make up the key and the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values associated with the key [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] will be represented with XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]].

The observation must be provided a key, which is either a value for the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] which is declared to be at the observation (% style="color:#e74c3c" %)level(%%) if the observation is grouped, or a full set of values for all [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] if the observation is un-grouped. This key should disambiguate the observation within the context in which it is defined (e.g. there should not be another observation with the same [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] value in a [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]]). The observation can contain an observed value and/or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values. [[Data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] schemas will derive a type or types based on this that is specific to the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] and the variation of the format being expressed in the schema. The [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] value(s) which make up the key and the data and metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values associated with the key [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]](s) or the primary [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] will be represented with XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]. This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived observation type will refine this structure so that the [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] are explicit. The XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be given a name based on the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]'s identifier. These XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be unqualified (meaning they do not have a namespace associated with them). The [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] XML [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]](s) will be required while the [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] will be optional. To allow for generic processing, it is required that the only unqualified XML [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] in the derived observation type be for the observation [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]](s) and [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] declared in the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]. If additional [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] are required, these should be qualified with a namespace so that a generic application can easily distinguish them as not being meant to represent a [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]].

173 |type|IDType|(% style="width:648px" %)The type [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] is used when the derived format requires that explicit [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] be used. In this case, the derived type based on the [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] will fix this value to be the identification of the [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] concept.

364 == 3.1 General ==
365
366 Data-structure-specific schemas are each based on one single core construct found in the structure-specific namespace:

368 Data - http://www.SDMX.org/resources/SDMXML/schemas/v3_1/data/structurespecific
369
370 === 3.1.1 Basic Terminology ===
371
372 In the subsequent sections, the following namespace prefixes are used:
373
374 |**Namespace**|**Prefix**|

378 | |metadata|
379
380 It is assumed that in order to use this guide, the reader is familiar with schema terminology. However, for convenience the following is list of the terminology used here:
381
382 **Schema:** Refers to the format specific schema in general, and in particular the root xs:schema element of that schema file.
383
384 **Global Element:** Refers to an element definition at the top level of the schema (i.e. an xs:element element in the root xs:schema element). It will define a name and type (name and type [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and possibly a substitution group (substitutionGroup [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
385
386 **Local Element:** Refers to an element definition within a complex type (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). A local element must define a name and type (name and type [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
387
388 **Qualified/Unqualified Element:** A qualified element is an element that must be referred to by the namespace in which it was defined. An unqualified element does not have a namespace associated with it. The structure-specific schemas make use of unqualified elements to that the structure-specific schemas can restrict the base content to meet the specific needs of the structure, while maintaining as much of the original document structure as possible.
389
390 **Element Reference:** Refers to an element definition within a complex type that is a reference to a global element (i.e. an xs:element element contained within a xs:sequence element that is contained in a xs:complexType element). An element reference must reference a global element (via its ref [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
391
392 **Complex Type:** Refers to a complex type definition. In this context, all complex type definitions occur at the top level of the schema (i.e. an xs:complexType element in the root xs:schema element). A complex type must define a name (name [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and may be made abstract (via the abstract [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]’s boolean value).
393
394 **Simple Type:** Refers to a simple type definition. In this context, all simple type definitions occur at the top level of the schema (i.e. an xs:simpleType element in the root xs:schema element). In this context, a simple type will always be defined via a restriction (an xs:restriction element in the xs:simpleType element). The restriction will reference a base type.
395
396 **Anonymous Type:** A complex or simple type definition which occurs within an element definition. The method is sometimes referred to a the "Russian-doll" technique as it creates nested constructs. Anonymous types are not given names and cannot be abstract. The can however, be derived from other types.
397
398 **Content Group:** A group which defines a content model for reuse. This is contained in the xs:group element and is defined at the root of the schema. It allows for a common sequence or choice of elements to be reused across multiple types without having to redefine the sequence or choice in each type.
399
400 **Uniqueness Constraint:** A uniqueness constraint is defined within an element and is used to force descendent elements to be unique based on some criteria of it fields (elements or [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]). This is defined in an \ element and has content of an \ and multiple \ elements. The selector designates the descendants that must be unique (with an xpath [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and the field specifies which property of the selected element must be unique (also with an xpath [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]])
401
402 **Extension:** Refers to the definition of a complex type that is an extension of another complex type. The extension will always make a reference to a base. In the schema, this is defined within the xs:complexType element as a child xs:complexContent element containing an xs:extension element (with a base [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
403
404 **Restriction:** Refers to the definition of a simple or complex type that is a restriction of another type of the same variety. The restriction will always make a reference to a base. In the schema, this is defined with an xs:restriction element (with a base [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
405
406 **Sequence:** Refers to a sequence of elements that may be defined as the root of a complex type content model, or as part of the content of a choice or another sequence. This is defined as an xs:sequence element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
407
408 **Choice:** Refers to a choice of elements that may be defined as the root of a complex type content model, or as part of the content of a sequence or another choice. This is defined as an xs:choice element. The sequence may specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
409
410 **[[Facet>>doc:sdmx:Glossary 2\.1.Facet.WebHome]]:** Refers to a single detail of a simple type restriction. This is represented by elements such as xs:minInclusive, xs:totalDigits, xs:minLength, and is contained in the xs:restriction element of a simple type definition. The value of the [[facet>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] is contained in a value [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] of the particular element.
411
412 **Enumeration:** Refers to an enumerated value of a simple type definition. It is represented by an xs:enumeration element contained within an xs:restriction element of a simple type definition. An enumeration defines a value (in the value [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and documentation (in xs:documentation elements contained in an xs:[[annotation>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]] element).
413
414 **XML [[Attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]:** Refers to the definition of an XML [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] for a complex type (i.e. and xs:[[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] element in a xs:complexType element). An [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] must define a name and type (name and type [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) and may also specify a usage (use [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]).
415
416 == 3.2 Namespace Rules ==
417
418 Each format specific schema will specify its namespace in the target namespace of the schema (the targetNamespace [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] of the schema). This document also assumes that the root namespace (that which is defined by the xmlns [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]) of the schema will be the same as the target namespace. Therefore, any types or global elements referenced in these descriptions without a namespace prefix are assumed to be in the format specific namespace.
419
420 The format specific schemas will incorporate the core format namespace and the common namespace by importing the schemas (via the xs:import element). If necessary, additional namespaces may be imported and referenced.
421
422 For the purpose of the descriptions here, the default element form for the schema (as specified in the elementFormDefault [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] of the schema) is "qualified", and the default [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] form (as specified in the attributeFormDefault [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] of the schema) is "unqualified".
423
424 == 3.3 General Rules ==
425
426 The following section details the general rules which apply to all structure-specific schema creation.
427
428 === 3.3.1 Component Name Determination ===
429
430 When required to create an XML element or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]], the name for a [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] is always its identifier. However, the identifier may be inherited. Therefore, the general rules are as follows:
431
432 1. If the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] defines an identifier, the element or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] name is the value of that identifier
433 1. Otherwise, the element or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] name is the identifier of the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] from which it takes its semantic (Note that this is technically the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] identifier).
434
435 === 3.3.2 Representation Determination ===
436
437 Every [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] has a [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] associated with it, whether it is defined as a local [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] in the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] definition, or it is inherited from the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] from which the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] takes it semantic (as defined in the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] identity of the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]]).
438
439 The [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of a [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] is determined by the following precedence:
440
441 1. The local [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] defined by the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]]
442 1. The core [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] defined in the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] from which the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] takes its semantic
443 1. A default [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of an un-faceted text format with a data type of String.
444
445 The [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] will either define a text format, an enumeration with an enumeration format, or a union of the former with the value of a irrelevant [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] ‘’ (tilde).
446
447 A text format consists of a data type and an optional collection of [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]]. It is the combination of these which determine the exact nature of the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]]. An enumeration consists of a reference to a [[codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]], [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]], or value list, for which an enumerated list of possible values can be created.
448
449 === 3.3.3 Simple / Primitive Type Determination ===
450
451 For any given [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]], there exist rules for determining the simple or primitive type which should be used to validate the value. There are no specific requirements to how a simple type is named or if it is referenced or used as an anonymous type. This section simply serves to state the requirements of the type for a [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] based on its [determined [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]]](#332-[[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]]-Determination).
452
453 For example, a [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] may inherit its [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] for a [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], and the data type of a [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] data type may be a String. The simplest solution would be to use the xs:string primitive type. However, an implementer may have chosen to generate simple types for all [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] to avoid having to look up the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] core [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] for very [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]]. In this case, the type may be given a name based on the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] and be a simple derivation from the xs:string type that places no further restrictions. The result would be that the type that is actually used for the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]], although named after the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], is effectively the required xs:string. These rules are meant to allow such flexibility in how types are created. The only requirement is that the type meet the requirements stated here.
454
455 === 3.3.4 Representation with Codelist Enumeration ===
456
457 A [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] which defines an enumeration from a [[codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] or [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] will result in a simple type that is a restriction of the common:IDType. The simple type will define enumerations for each [[code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] in the [[codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] or [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]], accounting for extensions. The value for these enumerations will be identifier of the item. If desired, the names of the item may be placed in the documentation of the enumeration, but this is not required. Example:
458
459 > <xs:simpleType name="ESTAT.CL\_COUNTRY.1.0">
460 > <xs:restriction base="common:IDType">
461 > <xs:enumeration value="BE">
462 > <xs:annotation>
463 > <xs:documentation xml:lang="en">Belgium</xs:documentation>
464 > </xs:annotation>
465 > </xs:enumeration>
466
467 === 3.3.5 Representation with Value List Enumeration ===
468
469 A [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] which defines an enumeration from a value list will result in a simple type that is a restriction of the xs:string data type. The simple type will define enumerations for each value item in the value list. The value for these enumerations will be identifier of the item. If desired, the names of the item may be placed in the documentation of the enumeration, but this is not required.
470
471 === 3.3.6 Representation with Simple Text Format ===
472
473 A [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] which defines a simple text format will result in a simple type or primitive type. The [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is simple if none of the following conditions are true:
474
475 * [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] max occurs is greater than 1
476 * text format data type is XHMTL
477 * text format is multi-lingual
478
479 If the [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is not simple, see the rules in the following section for complex text formats. If the [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is simple, the first step is to determine the base type from the text format data type:

524
525 If the text format does not specify any further [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]], then the determined type is the listed type or a type which derives from the listed type without placing any addition restrictions on it. However, if one or more [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] are specified, then a simple type based on the listed type is necessary. The simple type derives via restriction from the listed type and adds [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] according to the following table (the values are mapped as is):
526
527 (% style="width:1007.29px" %)

536 Any other [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] are informational only and will not affect the determined type.
537
538 === 3.3.7 Representation for Not Applicable Dimensions ===
539
540 Not applicable [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]], i.e., when reported [[measures>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] or [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] are not attached to those [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]], take as value the tilde ‘’ character. This is required for [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] defined by a [[DSD>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] that has the ‘evolving structure’ property set to true and that includes data from [[dataflows>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], which only use a subset of [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] as defined by a [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[constraint>>doc:sdmx:Glossary 2\.1.Constraint.WebHome]]. This is also required for data-related higher-level (i.e., attached to [[dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] or partial list of [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]) [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] that don’t have a fixed pre-defined attachment.
541
542 To support a specific type and allow for a not applicable [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] value, the structure-specific schema must union the type with the common:NotApplicableType, which enumerates the tilde ‘’ character. This is as shown in the following example:
543
544 > <xs:simpleType name="DecimalOrNotApplicableType">
545 > <xs:union memberTypes="xs:decimal common:NotApplicableType"/>
546 > </xs:simpleType>
547
548 For enumerated types, the generated structure-specific schema can include the special value in the enumeration or create a union between the enumerated type and the common:NotApplicableType.
549
550 Option 1: Augmenting the enumeration with the special value
551
552 > <xs:simpleType name="CL\_SUBINDICATOR\_OR\_NOT\_APPLICABLE">
553 > <xs:union memberTypes="CL\_SUBINDICATOR common:NotApplicableType"/>
554 > </xs:simpleType>
555
556 Option 2: Extending the enumeration with the special value
557
558 > <xs:simpleType name="CL\_ SUBINDICATOR ">
559 > <xs:restriction base="xs:string">
560 > <xs:enumeration value="A"/>
561 > <xs:enumeration value=""/>
562 > <xs:restriction>
563 > </xs:simpleType>
564
565 For convenience the common schema provides the union types for the following data types.

598 === 3.3.8 Representation for Intentionally Missing Measure and Attribute Values ===
599
600 For intentionally missing [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] and [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values, even if mandatory, the following special values can be used:
601
602 * NaN for all numeric types (float, double)
603 * #N/A for all other types
604
605 To support a specific type and allow for an intentionally missing [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]] or [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] value, the structure-specific schema must union the type with the common:MissingType, which enumerates the #N/A string. Note that XML natively already supports NaN for float and double values.
606
607 This union is as shown in the following example:
608
609 > <xs:simpleType name="DecimalOrMissingType">
610 > <xs:union memberTypes="xs:decimal common:MissingType"/>
611 > </xs:simpleType>
612
613 For enumerated types, the generated structure-specific schema can include the special value in the enumeration or create a union between the enumerated type and the common:MissingType.
614
615 Option 1: Augmenting the enumeration with the special value
616
617 > <xs:simpleType name="CL\_SUBINDICATOR\_OR\_NOT\_APPLICABLE">
618 > <xs:union memberTypes="CL\_SUBINDICATOR common:MissingType"/>
619 >  </xs:simpleType>
620
621 Option 2: Extending the enumeration with the special value
622
623 > <xs:simpleType name="CL\_ SUBINDICATOR ">
624 > <xs:restriction base="xs:string">
625 > <xs:enumeration value="A"/>
626 > <xs:enumeration value="#N/A"/>

663 === 3.3.9 Representation with Complex Text Format ===
664
665 A [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] which defines a complex text format will result in a complex type. The [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is complex if any of the following conditions are true:
666
667 * [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] max occurs is greater than 1
668 * text format data type is XHMTL
669 * text format is multi-lingual
670
671 The resulting complex type will be derived via restriction of the common:ValueType. In simple cases, there are pre-defined types that can be used:
672
673 * if the text format data type is XHTML, common:StructuredTextValueType can be used; note that this type cannot be further restricted – all other [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] are ignored
674 * if the text format is multi-lingual, common:TextValueType can be used; note that this type cannot be further restricted – all other [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] are ignored
675 * if the text format has no additional [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] and the data type is:
676 ** Boolean, common:BooleanValueType can be used
677 ** String, common:StringValueType can be used
678 ** Integer, common:IntValueType can be used
679 ** Double, common:DoubleValueType can be used
680 ** ObservationalTimePeriod, common:ObservationalTimePeriodValueType can be used
681
682 If a pre-defined type cannot be used, one will have to be created. The complex type must define a simple content restriction of the common:ValueType. The restriction should define an anonymous simple type based on the text format data type and [[facets>>doc:sdmx:Glossary 2\.1.Facet.WebHome]] as described in the previous section.
683
684 === 3.3.10 Type Names ===
685
686 These rules will only dictate type names where absolutely necessary. In all other cases, it is the decision of the implementer as to how to name or use the type. It is also the implementer's requirement to ensure that any type name is properly unique within its scope. To assist in this, the following recommendations are offered for naming types such that they are unique.
687
688 * It the type is an enumeration from an [[item scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]], the recommended name is ~[[[Item Scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]] Class].~[[[Maintenance Agency>>doc:sdmx:Glossary 2\.1.Maintenance agency.WebHome]]].~[[[Item Scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]] ID].~[[[Item Scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]] Version]
689 * If the type is based on a text format of a [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] core [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]], the recommended name is [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]].[Maintenance Agency].~[[[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] Scheme ID].~[[[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] Scheme Version].~[[[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] ID]
690 * If the type is
691 * based on a text format of a [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] local [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]], and;
692 ** The [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] id is required to be unique for all [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] within the scope of the structure which defines it (e.g. a [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]), the recommended name is ~[[[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ID]
693 ** The [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] id is only required to be unique within the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] list and which defines it (e.g. a metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]), the recommend name is ~[[[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] List ID].[Parent [[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ID]*.~[[[Component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ID]
694
695 === 3.3.11 Type Reuse ===
696
697 It is possible that organisations that manage a large number of structure-specific schemas my wish to take advantage of the reuse of previously defined type in order to simply the structure-specific schema creation and lessen the number of schema elements which are created. The structure-specific formats are designed in such a way that this would be allowed without any adverse affects.
698
699 For example, an organisation my create predefined types for all of [[codelists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] and [[concept schemes>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] which their structures utilize. These could be contained in a common schema with any namespace deemed appropriate. This would allow the structure-specific schemas generation process to recognize the reused [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] and not be concerned with regenerating types. The logical flow for setting the [[representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] of a [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] might be as follows:
700
701 Does the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] define a local type?
702 Yes: Is that type enumerated?
703 Yes: Type is the qualified type name for the [[item scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]]
704 No: Generate simple type for text format
705 No: Type is the qualified name for the [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] from which the [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] takes its semantic.
706
707 Only the constructs that will be detailed in the data and metadata structure-specific rules below are required to be in the specified target namespace of the structure-specific schema. So long as any other generated type conforms to the rules specified, it may exist in any namespace.
708
709 == 3.4 Data-Structure-Specific Schema ==
710
711 Separate schemas will be created for the data structure depending on which [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] occurs at the observation level. The recommended target namespace of the data structured specific schema is: [Data Structure URN]:ObsLevelDim:[Observation [[Dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]].
712
713 The rules for generating the data-structure-specific-schema are broken into sections based on the level within the structure (i.e. [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], group, [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]], [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]], observation). Each section will state the rules for each variation of the structure-specific format.
714
715 === 3.4.1 DataSetType ===
716
717 A complex type named DataSetType must be created. Its content model will be derived via restriction. The base type of the restriction is [[dsd>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]:DataSetType. The complex type content model will be as follows:
718
719 ~1. A sequence consisting of:
720
721 * i. An element reference to common:[[Annotations>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]], with a minimum occurrence of 0
722 * ii  A local element named DataProvider with the type common:DataProviderReferenceType, a form of unqualified and a minimum occurrence of 0
723 * iii A choice with a minimum occurrence of 0 and a maximum occurrence of unbounded consisting of:
724 ** a. A local element named Atts with a form of unqualified and a type of AttsType (as defined in the AttsType section which follows)
725 ** b. If the data structure defines groups, a local element named Group with a form of unqualified. The type of this element should be the type that is described in the GroupType section which follows.
726 ** c. If the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the observation level is not AllDimensions, a local element named [[Series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] with a form of unqualified and a type of SeriesType (as defined in the SeriesType section which follows)
727 ** d. If the [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] at the observation level is AllDimensions, a local element named Obs with a form of unqualified and a type of ObsType (as defined in the ObsType section which follows)
728 * iv. If any metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] usages defined in the data structure that declares an [[attribute relationship>>doc:sdmx:Glossary 2\.1.Attribute relationship.WebHome]] of [[dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], a local element named Metadata with the type metadata:MetadataSetType a form of unqualified, and a minimum occurences of 0
729
730 === 3.4.2 GroupType ===
731
732 If the [[data structure definition>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]] defines only one group, a complex type with its name taken from the identifier of the lone group must be defined. This type is used for the Group element in the DataSetType. Its content model will be derived via restriction of the [[dsd>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]:GroupType. The complex type content model will be as follows:
733
734 ~1. A sequence consisting of:
735
736 * i. An element reference to common:[[Annotations>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]], with a minimum occurrence of 0
737 * ii. If any [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] defined in the data structure that declares an [[attribute relationship>>doc:sdmx:Glossary 2\.1.Attribute relationship.WebHome]] with the group, a Comp element with a form of unqualified, a minimum occurrence of 0, a maximum occurrence of unbounded, and a type of [[dsd>>doc:sdmx:Glossary 2\.1.Data structure definition.WebHome]]:CompType
738 * iii. If any metadata [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] usages defined in the data structure that declares an [[attribute relationship>>doc:sdmx:Glossary 2\.1.Attribute relationship.WebHome]] with the group, a local element named Metadata with the type metadata:MetadataSetType a form of unqualified, and a minimum occurrence of 0
739

830 == 4.1 Data Actions ==
831
832 Data messages allow indicating intended actions when used to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system. This purpose is noted in the action of the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], which is either inherited from the header of the data message or explicitly stated at the [[data set>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] (% style="color:#e74c3c" %)level(%%).
833
834 Note that the former //Append// and //Information// actions are deprecated. When used to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system, the //Merge// action is assumed.
835
836 === 4.1.1 Merge Action ===
837
838 Data or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] is to be merged, through either update or insertion depending on already existing information. This operation does not allow deleting any [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] values. Updating individual values in multi-valued [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values is not supported either. The complete multi-valued value is to be provided.
839
840 Only non-dimensional [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ([[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values) can be **omitted** (null or absent) as long as at least one of those [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] is present. Bulk merges are thus not supported. Only the provided values are merged.
841
842 [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values for higher-level (data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]) [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] can be **switched-off** (using ) when those are not attached to these [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]].
843
844 All observations as well as the sets of data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] at specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combinations impacted by the //Merge// action change their time stamp when used to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system.
845
846 === 4.1.2 Replace Action ===
847
848 Data or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] is to be replaced, through either update, insert or delete depending on already existing information. A full replacement is hereby assumed to take place at specific “//replacement levels//”: for entire observations and for any specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combination for data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]. Within these “replacement levels” the provided values are inserted or updated, and omitted values are deleted. Values provided for the other [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] (those above the observation level) are merged (see //Merge// action).
849
850 Only non-dimensional [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]] ([[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] or [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values) can be **omitted** (null or absent). Bulk replacing is thus not supported.
851
852 [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values for higher-level (data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]) [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] can be **switched-off** (using ) when those are not attached to these [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]].
853
854 Replacing non-existing elements is not resulting in an error.
855
856 All observations as well as the sets of data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] at specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combinations impacted by the //Replace// action change their time stamp when used to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system.
857
858 Because the //replace// action always takes place at specific levels, it cannot be used to replace a whole [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] or a whole [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]]. However, a //“replace all”// effect can be achieved by combining a //Delete// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] containing a completely wildcarded key (where all [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values are omitted) with a //Merge// or //Replace// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] within the same data message. Similarly, to replace a whole [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]], a message can combine a //delete// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] containing only the partial key of the [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]] (where the not used [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values are omitted) with a //Merge// or //Replace// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] for that [[series>>doc:sdmx:Glossary 2\.1.Series.WebHome]].
859
860 === 4.1.3 Delete Action ===
861
862 Data or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] is to be deleted. Deletion is hereby assumed to take place at the lowest level of detail provided in the message.
863
864 Any [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] (including [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]) can be **omitted** ([[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]]: empty, others: null or absent). Omitting [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values allows for bulk deletions. Partially omitting non-[[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] [[component>>doc:sdmx:Glossary 2\.1.Component.WebHome]] values allows restricting the deletion of [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values to the ones being present. Instead of real values for non-dimensional [[components>>doc:sdmx:Glossary 2\.1.Component.WebHome]], it is sufficient to use any valid value.
865
866 With this, whole [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]], any slices of observations for [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] groups such as [[time series>>doc:sdmx:Glossary 2\.1.Series.WebHome]], observations or individual [[measure>>doc:sdmx:Glossary 2\.1.Measure.WebHome]], [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] and data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values can be deleted.
867
868 [[Dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] values for higher-level (data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]) [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] can be **switched-off** (using ) when those are not attached to these [[dimensions>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]].
869
870 Deleting non-existing elements or values is not resulting in an error.
871
872 All observations as well as the sets of [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] and data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] at higher partial keys impacted by the //Delete// action change their time stamp when used to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system.

888 **Important notes:**
889
890 The terms “//delete//”, “//merge//” and “//replace//” do **not** imply a physical replacement or deletion of values in the underlying database. To minimize the physical resource requirements, [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] web service implementations that do not support the //includeHistory// and //asOf// URL parameters might physically replace the existing values in the database. [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] web services that neither support the //updatedAfter// URL parameter might also implement physical deletions. However, [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] web services that support these parameters (or other time-machine features), would not overwrite or delete the physical values.
891
892 [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] web services that support the //includeHistory// or //asOf// URL parameters should never allow deleting their **historic** data content because this would interfere with the interests of [[data consumers>>doc:sdmx:Glossary 2\.1.Data consumer.WebHome]], such as data aggregators. Therefore, a specific feature to physically delete previous (outdated) content is intentionally not added to the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] standard syntax. If such a feature is required by an organisation, then it needs to be implemented as a custom feature outside the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] standard.
893
894 Likewise, all [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]]-compliant systems that do (or are configured to) support the //updatedAfter// URL parameter need to systematically retain the information about deleted data (or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]).
895
896 All [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] – even with varying actions – within a single data message have always to be treated as **ACID transaction** to guarantee “transactional safety” (full data consistency and validity despite errors, power failures, and other mishaps). These [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] are to be processed in the order of appearance in the message. The advantage of such data messages is thus the ability to bundle separate //delete// and //replace// or //merge// actions into one transactional data message.
897
898 **Recommended{{footnote}}So far this is recommended for systems that do not require backward-compatibility. Later, with SDMX 4.0, this may generally be made mandatory{{/footnote}} dataset actions in SDMX web service responses to GET data queries:**
899
900 ~1. Without the //updatedAfter//, //includeHistory//, //detail//, //[[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]// or //[[measures>>doc:sdmx:Glossary 2\.1.Measure.WebHome]]// URL parameters:
901
902 The response message should contain the retrieved data in a //Replace// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] (instead of the previous //information// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]).
903
904 2. Without the //updatedAfter// and //includeHistory//, but with //detail//, //[[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]// or //[[measures>>doc:sdmx:Glossary 2\.1.Measure.WebHome]]// URL parameters:
905
906 The response message should contain the retrieved data in a //Merge// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] (instead of the previous //Information// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]]).
907
908 3. With the //updatedAfter// URL parameter:
909
910 The response must include the information of all previously updated, inserted and deleted data or data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]], even if bulk deletions have been used. One of the two approaches are possible:
911
912 * a //Delete// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] for entirely deleted observations and for entirely deleted sets of (data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]) [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values attached to specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combinations and
913 a //Replace// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] for all other changed observations and changed [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] and data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values attached to specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combinations, or
914 * a //Delete// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] for entirely deleted observations, for entirely deleted sets of (data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]]) [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] values attached to specific [[dimension>>doc:sdmx:Glossary 2\.1.Dimension.WebHome]] combinations and for individually deleted mesure, [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] and [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values and
915 a //Merge// [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] for all other updated or inserted observation, [[attribute>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]] and data-related [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] values.
916
917 The DB synchronization use case requires that the generated response must always allow achieving to replicate the exact same punctual data content as currently stored in the queried [[data source>>doc:sdmx:Glossary 2\.1.Data source.WebHome]].
918
919 ~1. With the //includeHistory// URL parameter:
920
921 Using a number of [[datasets>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] with //Delete//, //Replace// or //Merge// actions and limited in their validity time span that allow achieving to replicate the exact same punctual data contents as previously stored in the queried [[data source>>doc:sdmx:Glossary 2\.1.Data source.WebHome]].
922
923 2. With the //asOf// URL parameter:
924
925 The recommendations of 1 and 2 apply depending on the other parameters. In addition, the returned [[dataset>>doc:sdmx:Glossary 2\.1.Data set.WebHome]] should have its validity time span limited to the point in time requested in the //asOf// parameter.
926
927 == 4.2 Reference Metadata Actions ==
928
929 [[Reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] defined by a [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]] or a MetadataProvisionAgreement are exchanged within reference metadatasets, which are maintainable and thus for actions behave like [[structural metadata>>doc:sdmx:Glossary 2\.1.Structural metadata.WebHome]] ([[artefacts>>doc:sdmx:Glossary 2\.1.Artefact.WebHome]]): When interacting with [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Rest web services, the HTTP action verbs GET, PUT and POST are used to indicate the intended action per web request. Consequently, different actions cannot be bundled and executed with “transactional ACIDity”. Note that metadatasets retrieved using the HTTP header “Accept-[[Language>>doc:sdmx:Glossary 2\.1.Language.WebHome]]” may contain only partial [[languages>>doc:sdmx:Glossary 2\.1.Language.WebHome]], and thus should be marked with its //isPartialLanguage// property set to true. Submitting such a partial metadataset to update an [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] storage system will only add or update the included [[languages>>doc:sdmx:Glossary 2\.1.Language.WebHome]] but not change other [[languages>>doc:sdmx:Glossary 2\.1.Language.WebHome]].
930
931 The former message header or metadataset property //DataSetAction// is deprecated. To avoid conflicts, it is now ignored if still present.
