	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, where format is either generic or structured (i.e. the structure specific formats). This also applies to the message names as well, where the names follow the pattern of FormatData (e.g. StructuredData and GenericMetadata).
	8
10.2	9	The various data messages which existed in the standard have been harmonised into two general formats; generic and structured data. The generic data is much like it has been previously, only slightly modified to conform with the harmonised view on data. The structured data combined the principles of the previous (% style="color:#e74c3c" %)versions(%%) compact and cross sectional formats into one more generalised format.
4.2	10
10.2	11	The major shift from the previous (% style="color:#e74c3c" %)version(%%) is now that all data can be exchanged as either an un-grouped collection oData structure and metadata structure-specific schemas are each based on one single core construct found in their respective structure-specific namespaces;f observations, each specifying a full key or it can be exchanged as data grouped into series with any single [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] placed at the observation (% style="color:#e74c3c" %)level(%%). This in effect, combined the abilities of the time series and cross sectional formats in the a single data format. This format also allows for multiple [[measure>>doc:sdmx:Glossary.Measure.WebHome]] to be expressed when the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the [[measure>>doc:sdmx:Glossary.Measure.WebHome]] [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] defined in the data structured. The key differences from the previous (% style="color:#e74c3c" %)versions(%%) is that this all is possible in a single [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific format, as well as being possible in the generic format as well. The goal was to make the structures as homogenous as possible.
4.2	12
10.2	13	Another shift from the previous (% style="color:#e74c3c" %)version(%%) in the manner in which the base data structure specific format is defined. In previous (% style="color:#e74c3c" %)versions(%%) there was not structure defined, so one had to understand all of the requirements and read the specification in order to understand what could be expected in any structure specific format. In this (% style="color:#e74c3c" %)version(%%), that issue has been addressed. The base structures now impose a strict format on the data structure specific schemas. This is achieved much like the referencing structure in the common namespace through the use of unqualified elements. By the elements not existing in a namespace, the structure specific schemas can place the necessary restrictions of them while still being forced to adhere to prescribed structure. This means that not only are the structures able to perform the validation that is required, but that the messages will be much simpler to process as the format will always use the same element names.
4.2	14
10.2	15	Finally, in order to allow for systems which wish to not process the new more flexible data format, time series only variations of both the generic and structured [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] exist. It is important to note that these structures are derived via restriction from the more generalised format. This means that a [[data set>>doc:sdmx:Glossary.Data set.WebHome]] in the general format with the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation (% style="color:#e74c3c" %)level(%%) will have exactly the same content as a time series only [[data set>>doc:sdmx:Glossary.Data set.WebHome]]. The result of this is that there is no additional burden for processing the time series specific format it a system can process the more generalised format. These time series only [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] allow for time series only data messages to exist. These messages make it simple for system which, in the previous (% style="color:#e74c3c" %)version(%%) of the standard, only used the time series formats to continue to do so.
4.2	16
10.2	17	These same principles have been applied to the reference data messages as well. In the previous (% style="color:#e74c3c" %)version(%%) of the standard there were major differences between the generic and metadata structure-specific formats; some of the differences caused some [[metadata sets>>doc:sdmx:Glossary.Metadata set.WebHome]] were incompatible between (% style="color:#e74c3c" %)versions(%%). In this (% style="color:#e74c3c" %)version(%%) the structures of the generic and metadata structure specific formats have been harmonised to the point where they are nearly identical. Yet, the structured format still provides the strong validation against the metadata structure that is intended. And, as with the data, the base metadata structure specific format now imposes a stricter structure on the generated schemas, making the structure specific instance simpler to process in a generic manner.

10.2	39	DataSetType: DataSetType defines the structure of the generic [[data set>>doc:sdmx:Glossary.Data set.WebHome]]. Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The organisation used is dependent on the structure specification in the header of the data message (which is referenced via the structureRef [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]). The structure specification states which data occurs at the observation (% style="color:#e74c3c" %)level(%%). If this [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is "AllDimensions" then the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] must consist of a collection of un-grouped observations; otherwise the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] will contain a collection of series with the observations in the series disambiguated by the specified [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation (% style="color:#e74c3c" %)level(%%). This [[data set>>doc:sdmx:Glossary.Data set.WebHome]] is capable of containing data (observed values) and/or documentation ([[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values). It is assumed that each series or un-grouped observation will be distinct in its purpose. For example, if series contains both data and documentation, it assumed that each series will have a unique key. If the series contains only data or only documentation, then it is possible that another series with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first series.

In addition to the key and observations, the series contains values for [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] which have a relationship with any [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] that is part of the [[series key>>doc:sdmx:Glossary.Series key.WebHome]], so long as the [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] does not specify an attachment group or also has a relationship with the [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] declared to be at the observation (% style="color:#e74c3c" %)level(%%).
	75	\|Obs\|ObsOnlyType\|(% style="width:642px" %)Obs is an un-grouped observation. This observation has a key which is a set of values for all [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]] declared in the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. In addition to the key, the value of the observation can be provided along with values for all [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] which have an association with the primary [[measure>>doc:sdmx:Glossary.Measure.WebHome]] or any [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] (so long as it does not specify a group attachment).

10.2	77	GroupType: GroupType defines a structure which is used to communicate [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values for a group defined in a [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. The group can consist of either a subset of the [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]] defined by the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]], or an association to an attachment (% style="color:#e74c3c" %)constraint(%%), which in turn defines key sets to which [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] can be attached. In the case that the group is based on an attachment (% style="color:#e74c3c" %)constraint(%%), 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 (% style="color:#e74c3c" %)constraint(%%) and apply the values provided for the [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] appropriately.

10.2	227	TimeSeriesDataSetType: TimeSeriesDataSetType is a derivation of the base DataSetType of the generic format the restricts the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] to only allow for grouped observations where the [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation (% style="color:#e74c3c" %)level(%%) is the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] of the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. This means that unlike the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] structure, there can be no un-grouped observations. Because this derivation is achieved using restriction, [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] conforming to this type will inherently conform to the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] structure as well. In fact, data structured here will be identical to data in the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] when the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]]. This means that the data contained in this structure can be processed in exactly the same manner as the base structure.

10.2	344	//DataSetType//: DataSetType is the abstract type which defines the base structure for any [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific [[data set>>doc:sdmx:Glossary.Data set.WebHome]]. A derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will be created that is specific to a [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] and the details of the organisation of the data (i.e. which [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] and whether explicit [[measures>>doc:sdmx:Glossary.Measure.WebHome]] should be used). Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will restrict this choice to be either grouped or un-grouped observations. If this [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is "AllDimensions" then the derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type must consist of a collection of un-grouped observations; otherwise the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] will contain a collection of series with the observations in the series disambiguated by the specified [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation (% style="color:#e74c3c" %)level(%%). This [[data set>>doc:sdmx:Glossary.Data set.WebHome]] is capable of containing data (observed values) and/or documentation ([[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values) and can be used for [[incremental updates>>doc:sdmx:Glossary.Incremental update.WebHome]] and deletions (i.e. only the relevant updates or deletes are exchanged). It is assumed that each series or un-grouped observation will be distinct in its purpose. For example, if series contains both data and documentation, it assumed that each series will have a unique key. If the series contains only data or only documentation, then it is possible that another series with the same key might exist, but with not with the same purpose (i.e. to provide data or documentation) as the first series. 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.Data structure definition.WebHome]] specific data will have a consistent structure. The group, series, and observation 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.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.Data structure definition.WebHome]] specific schema. The [[data set>>doc:sdmx:Glossary.Data set.WebHome]] can contain values for [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] which do not have an [[attribute relationship>>doc:sdmx:Glossary.Attribute relationship.WebHome]] with any [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] [[components>>doc:sdmx:Glossary.Component.WebHome]]. These [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values will exist in XML [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] in this element based on this type ([[DataSet>>doc:sdmx:Glossary.Data set.WebHome]]). This is specified in the content model with the declaration of anyAttributes in the "local" namespace. The derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will refine this structure so that the [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] are explicit. The XML [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] will be given a name based on the [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]'s identifier. These XML [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] will be unqualified (meaning they do not have a namespace associated with them). To allow for generic processing, it is required that the only unqualified XML [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] in the derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type (outside of the standard [[data set>>doc:sdmx:Glossary.Data set.WebHome]] [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) be for [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] declared in the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. If additional [[attributes>>doc:sdmx:Glossary.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.Data structure definition.WebHome]] [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]].

10.2	461	//TimeSeriesDataSetType//: TimeSeriesDataSetType is the abstract type which defines the base structure for any [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] specific time series based [[data set>>doc:sdmx:Glossary.Data set.WebHome]]. A derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type will be created that is specific to a [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. Unlike the base format, only one variation of this is allowed for a [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]]. This variation is the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] as the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]]. Data is organised into a collection of time series. Because this derivation is achieved using restriction, [[data sets>>doc:sdmx:Glossary.Data set.WebHome]] conforming to this type will inherently conform to the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] structure as well. In fact, data structure specific here will be identical to data in the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] when the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]], even for the derived [[data set>>doc:sdmx:Glossary.Data set.WebHome]] types. This means that the data contained in this structure can be processed in exactly the same manner as the base structure. The same rules for derivation as the base [[data set>>doc:sdmx:Glossary.Data set.WebHome]] type apply to this specialized [[data set>>doc:sdmx:Glossary.Data set.WebHome]].

	903	For a metadata structure, only a single schema will be created for the entire structure definition. For data structures, many variations of the base schema are possible, each specific as to how the data is organised. This will be discussed in more details in the specific rules for the data structure schemas.

4.2	915
	916	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:
	917
	918	Schema: Refers to the format specific schema in general, and in particular the root xs:schema element of that schema file.
	919
10.2	920	Global Element: Refers to an element definition at the top (% style="color:#e74c3c" %)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.Attribute.WebHome]]) and possibly a substitution group (substitutionGroup [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
4.2	921
10.2	922	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.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
4.2	923
	924	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.
	925
10.2	926	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.Attribute.WebHome]]) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
4.2	927
10.2	928	Complex Type: Refers to a complex type definition. In this context, all complex type definitions occur at the top (% style="color:#e74c3c" %)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.Attribute.WebHome]]) and may be made abstract (via the abstract [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]’s boolean value).
4.2	929
10.2	930	Simple Type: Refers to a simple type definition. In this context, all simple type definitions occur at the top (% style="color:#e74c3c" %)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.
4.2	931
	932	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.
	933
	934	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.
	935
10.2	936	Uniqueness (% style="color:#e74c3c" %)Constraint(%%): A uniqueness (% style="color:#e74c3c" %)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.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.Attribute.WebHome]]) and the field specifies which property of the selected element must be unique (also with an xpath [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]])
4.2	937
10.2	938	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.Attribute.WebHome]]).
4.2	939
10.2	940	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.Attribute.WebHome]]).
4.2	941
10.2	942	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.Attribute.WebHome]]).
4.2	943
10.2	944	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.Attribute.WebHome]]).
4.2	945
10.2	946	[[Facet>>doc:sdmx:Glossary.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.Facet.WebHome]] is contained in a value [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the particular element.
4.2	947
10.2	948	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.Attribute.WebHome]]) and documentation (in xs:documentation elements contained in an xs:[[annotation>>doc:sdmx:Glossary.Annotation.WebHome]] element).
4.2	949
10.2	950	XML [[Attribute>>doc:sdmx:Glossary.Attribute.WebHome]]: Refers to the definition of an XML [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] for a complex type (i.e. and xs:[[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] element in a xs:complexType element). An [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] must define a name and type (name and type [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) and may also specify a usage (use [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]).
4.2	951
6.1	952	== 3.2 Namespace Rules ==
4.2	953
10.2	954	Each format specific schema will specify its namespace in the target namespace of the schema (the targetNamespace [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema). This document also assumes that the root namespace (that which is defined by the xmlns [[attribute>>doc:sdmx:Glossary.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.
4.2	955
	956	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.
	957
10.2	958	For the purpose of the descriptions here, the default element form for the schema (as specified in the elementFormDefault [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema) is “qualified", and the default [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] form (as specified in the attributeFormDefault [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] of the schema) is "unqualified".
4.2	959
6.1	960	== 3.3 General Rules ==
4.2	961
	962	The following section details the general rules which apply to all structure specific schema creation.
	963
6.1	964	=== 3.3.1 Component Name Determination ===
4.2	965
10.2	966	When required to create an XML element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]], the name for a [[component>>doc:sdmx:Glossary.Component.WebHome]] is always its identifier. However, the identifier may be inherited. Therefore, the general rules is as follows:
4.2	967
10.2	968	1. If the [[component>>doc:sdmx:Glossary.Component.WebHome]] defines an identifier, the element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] name is the value of that identifier
	969	1. Otherwise, the element or [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] name is the identifier of the (% style="color:#e74c3c" %)concept(%%) from which it takes its semantic (Note that this is technically the [[component>>doc:sdmx:Glossary.Component.WebHome]] identifer).
4.2	970
6.1	971	=== 3.3.2 Representation Determination ===
	972
10.2	973	Every [[component>>doc:sdmx:Glossary.Component.WebHome]] has a [[representation>>doc:sdmx:Glossary.Representation.WebHome]] associated with it, whether it is defined as a local [[representation>>doc:sdmx:Glossary.Representation.WebHome]] in the [[component>>doc:sdmx:Glossary.Component.WebHome]] definition, or it is inherited from the (% style="color:#e74c3c" %)concept(%%) from which the [[component>>doc:sdmx:Glossary.Component.WebHome]] takes it semantic (as defined in the (% style="color:#e74c3c" %)concept(%%) identity of the [[component>>doc:sdmx:Glossary.Component.WebHome]]).
4.2	974
10.2	975	The [[representation>>doc:sdmx:Glossary.Representation.WebHome]] of a [[component>>doc:sdmx:Glossary.Component.WebHome]] is determined by the following precedence:
4.2	976
10.2	977	1. The local [[representation>>doc:sdmx:Glossary.Representation.WebHome]] defined by the [[component>>doc:sdmx:Glossary.Component.WebHome]]
	978	1. The core [[representation>>doc:sdmx:Glossary.Representation.WebHome]] defined in the (% style="color:#e74c3c" %)concept(%%) from which the [[component>>doc:sdmx:Glossary.Component.WebHome]] takes its semantic
	979	1. A default [[representation>>doc:sdmx:Glossary.Representation.WebHome]] of an un-faceted text format with a data type of String.
4.2	980
10.2	981	The [[representation>>doc:sdmx:Glossary.Representation.WebHome]] will either define a text format, or an enumeration with an enumeration format.
4.2	982
10.2	983	A text format consists of a data type and an optional collection of [[facets>>doc:sdmx:Glossary.Facet.WebHome]]. It is the combination of these which determine the exact nature of the [[component>>doc:sdmx:Glossary.Component.WebHome]] [[representation>>doc:sdmx:Glossary.Representation.WebHome]]. An enumeration consists of a reference to an [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]], for which an enumerated list of possible values can be created.
4.2	984
6.1	985	=== 3.3.3 Simple / Primitive Type Determination ===
4.2	986
10.2	987	For any given [[representation>>doc:sdmx:Glossary.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.Component.WebHome]] based on its determined [[representation>>doc:sdmx:Glossary.Representation.WebHome]].
4.2	988
10.2	989	For example, a [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] may inherit its [[representation>>doc:sdmx:Glossary.Representation.WebHome]] for a (% style="color:#e74c3c" %)concept(%%), and the data type of a [[representation>>doc:sdmx:Glossary.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 (% style="color:#e74c3c" %)concepts(%%) to avoid having to look up the (% style="color:#e74c3c" %)concept(%%) core [[representation>>doc:sdmx:Glossary.Representation.WebHome]] for very [[component>>doc:sdmx:Glossary.Component.WebHome]]. In this case, the type may be given a name based on the (% style="color:#e74c3c" %)concept(%%) 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.Dimension.WebHome]], although named after the (% style="color:#e74c3c" %)concept(%%), 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.
4.2	990
6.1	991	=== 3.3.4 Representation with Enumeration ===
4.2	992
10.2	993	A [[representation>>doc:sdmx:Glossary.Representation.WebHome]] which defines an enumeration will result in a simple type that is a restriction of the common:IDType. The simple type will define enumerations for each item in the [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]]. 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:
4.2	994
4.7	995	> <xs:simpleType name="ESTAT.CL_COUNTRY.1.0">
	996	> <xs:restriction base="common:IDType">
	997	> <xs:enumeration value="BE">
	998	> <xs:annotation>
	999	> <xs:documentation xml:lang="en">Belgium</xs:documentation>
	1000	> </xs:annotation>
	1001	> </xs:enumeration>
4.2	1002

10.2	1054	If the text format does not specify any further [[facets>>doc:sdmx:Glossary.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.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.Facet.WebHome]] according to the following table (the values are (% style="color:#e74c3c" %)mapped(%%) as is):

4.2	1066
6.1	1067	=== 3.3.6 Type Names ===
4.2	1068
	1069	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.
	1070
10.2	1071	* It the type is an enumeration from an [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]], the recommended name is ~[[[Item Scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] Class].[Maintenance Agency].~[[[Item Scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] ID].~[[[Item Scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] (% style="color:#e74c3c" %)Version(%%)]
	1072	* If the type is based on a text format of a (% style="color:#e74c3c" %)concept(%%) core [[representation>>doc:sdmx:Glossary.Representation.WebHome]], the recommended name is (% style="color:#e74c3c" %)Concept(%%).[Maintenance Agency].~[[[Concept Scheme>>doc:sdmx:Glossary.Concept scheme.WebHome]] ID].~[[[Concept Scheme>>doc:sdmx:Glossary.Concept scheme.WebHome]] (% style="color:#e74c3c" %)Version(%%)].[(% style="color:#e74c3c" %)Concept(%%) ID]
	1073	* If the type is based on a text format of a [[component>>doc:sdmx:Glossary.Component.WebHome]] local [[representation>>doc:sdmx:Glossary.Representation.WebHome]], and;
	1074	** The [[component>>doc:sdmx:Glossary.Component.WebHome]] id is required to be unique for all [[components>>doc:sdmx:Glossary.Component.WebHome]] within the scope of the structure which defines it (e.g. a [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]]), the recommended name is ~[[[Component>>doc:sdmx:Glossary.Component.WebHome]] ID]
	1075	** The [[component>>doc:sdmx:Glossary.Component.WebHome]] id is only required to be unique within the [[component>>doc:sdmx:Glossary.Component.WebHome]] list and which defines it (e.g. a metadata [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]]), the recommend name is ~[[[Component>>doc:sdmx:Glossary.Component.WebHome]] List ID].[Parent [[Component>>doc:sdmx:Glossary.Component.WebHome]] ID]*.~[[[Component>>doc:sdmx:Glossary.Component.WebHome]] ID]
4.2	1076
6.1	1077	=== 3.3.7 Type Reuse ===
	1078
4.2	1079	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.
	1080
10.2	1081	For example, an organisation my create predefined types for all of [[codelists>>doc:sdmx:Glossary.Code list.WebHome]] and [[concept schemes>>doc:sdmx:Glossary.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.Component.WebHome]] and not be concerned with regenerating types. The logical flow for setting the [[representation>>doc:sdmx:Glossary.Representation.WebHome]] of a [[component>>doc:sdmx:Glossary.Component.WebHome]] might be as follows:
4.2	1082
6.1	1083	> Does the component define a local type?
	1084	> Yes: Is that type enumerated?
	1085	> Yes: Type is the qualified type name for the item scheme
	1086	> No: Generate simple type for text format
	1087	> No: Type is the qualified name for the concept from which the component takes its semantic.
4.2	1088
	1089	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.
	1090
6.1	1091	== 3.4 Data Structure Specific Schema ==
4.2	1092
10.2	1093	Separate schemas will be created for the data structure depending on which [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] occurs at the observation (% style="color:#e74c3c" %)level(%%), and whether explicit [[measures>>doc:sdmx:Glossary.Measure.WebHome]] are used in the case that the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is the [[measure>>doc:sdmx:Glossary.Measure.WebHome]] [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]]. The recommended target namespace of the data structured specific schema is: [Data Structure URN]:ObsLevelDim:[Observation [[Dimensions>>doc:sdmx:Glossary.Dimension.WebHome]]](:explicit)?. Note that the explicit trailer is only used when the [[measure>>doc:sdmx:Glossary.Measure.WebHome]] [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] is used at the observation (% style="color:#e74c3c" %)level(%%) and the explicit [[measure>>doc:sdmx:Glossary.Measure.WebHome]] (% style="color:#e74c3c" %)concepts(%%) are to be used.
4.2	1094
10.2	1095	The rules for generating the data structure specific-schema are broken into sections based on the (% style="color:#e74c3c" %)level(%%) within the structure (i.e. [[data set>>doc:sdmx:Glossary.Data set.WebHome]], group, series, observation). Each section will state the rules for each variation of the structure specific format.
4.2	1096
6.1	1097	=== 3.4.1 DataSetType ===
4.2	1098
10.2	1099	A complex type named DataSetType must be created. Its content model will be derived via restriction. If the [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] at the observation (% style="color:#e74c3c" %)level(%%) is the time [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] (TIME_PERIOD) the base type of the restriction is [[dsd>>doc:sdmx:Glossary.Data structure definition.WebHome]]:TimeSeriesDataSetType. Otherwise, the base type of the restriction is [[dsd>>doc:sdmx:Glossary.Data structure definition.WebHome]]:DataSetType. The complex type content model will be as follows:

10.2	1115	If the [[data structure definition>>doc:sdmx:Glossary.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.Data structure definition.WebHome]]:GroupType. The complex type content model will be as follows:

6.1	1255	==== 3.5.2.1 Identifiable Object Target Type Determination ====
5.1	1256
10.2	1257	An identifiable object target is meant to reference an [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] identifiable object. In the metadata structure specific schema, the complex type which defines the reference is restricted according to the local [[representation>>doc:sdmx:Glossary.Representation.WebHome]] and object type of the identifiable object target. If the identifiable object target does not provide an enumeration in its local [[representation>>doc:sdmx:Glossary.Representation.WebHome]], then the complex type for the target object is the specific reference type from the common namespace, based on the object type defined by the target object. For example, if the object type is DataProivder, the type will be common:DataProviderReferenceType. The general rule for the name of this type is common:[object type]ReferenceType.
4.2	1258
10.2	1259	If the target object defines an enumeration in its local [[representation>>doc:sdmx:Glossary.Representation.WebHome]], then the declared object type must be for the items contained the enumeration's referenced [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]]. If this is not true, the reference type as defined above is the type for the target object.
4.2	1260
10.2	1261	If the object type does correspond with the enumeration [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]], then the type is complex type which restricts the reference to the allowable values. In order to construct this type, the following must be created:
4.2	1262
10.2	1263	A simple type which enumerates with URNs of the items contained in the [[items scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] referenced from the enumeration. The recommended name is ~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] agency].~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] identifier].~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] (% style="color:#e74c3c" %)version(%%)].URN. This simple type should restrict the xs:anyURI type an contain enumerations with values of the URN of every item defined by the scheme.
4.2	1264
10.2	1265	A second simple type which enumerates the IDs of the items contained in the [[items scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] referenced from the enumeration. The recommended name is ~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] agency].~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] identifier].~[[[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] (% style="color:#e74c3c" %)version(%%)].ID. This simple type should restrict the either the common:NestedIDType for hierarchical items or the common:IDType for flat items. The restriction should contain enumerations with values of the ID of every item defined by the scheme. For hierarchical items (such as [[categories>>doc:sdmx:Glossary.Category.WebHome]]), the id should be nested to reflect the full path (e.g. A.C.D.F).
4.2	1266
10.2	1267	A complex type which restricts the full set of reference fields for the item to be reference must be created. The recommended name is [metadata target].[target object].Ref. This type is derived via restriction of the type which defines the full set of reference fields for the item referenced by the target object. For example, if the object type is [[Category>>doc:sdmx:Glossary.Category.WebHome]], the type that is the base of the restriction is common:CategoryRefType. . The general rule for the name of this type is common:[object type]RefType. The content model of this type must be as follows:
4.2	1268
10.2	1269	1. An [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] named agencyID with a type of common:NestNCNameIDType, a use of required, and a fixed value of the [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] referenced from the enumeration
	1270	1. An [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] named maintinableParentID with a type of common:IDType, a use of required, and a fixed value of the identifier of the [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] referenced from the enumeration
	1271	1. An [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] named maintainableParentVersion with a type of common:VersionType, a use of optional, and a fixed value of the (% style="color:#e74c3c" %)version(%%) of the [[item scheme>>doc:sdmx:Glossary.Item scheme.WebHome]] referenced from the enumeration

6.1	1299
4.2	1300	For each metadata target referenced from the report structure, a complex type that must be named [report structure identifier].[metadata target identifier] must be created.

This purpose is noted in the action for the [[data set>>doc:sdmx:Glossary.Data set.WebHome]], which is either inherited from the header of the data message or explicitly stated at the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] (% style="color:#e74c3c" %)level(%%).

10.2	1345	A [[dataset>>doc:sdmx:Glossary.Data set.WebHome]] with an action of Append is assumed to be an [[incremental update>>doc:sdmx:Glossary.Incremental update.WebHome]]. This means that one the information provided explicitly in the message should be altered. Any data [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] or [[observation value>>doc:sdmx:Glossary.Observation value.WebHome]] that is to be changed must be provided. However, the absence of an [[observation value>>doc:sdmx:Glossary.Observation value.WebHome]] or a data [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] at any (% style="color:#e74c3c" %)level(%%) does not imply deletion; instead it is simply implied that the value is to remain unchanged. Therefore, it is valid and acceptable to send a data message with an action of Append which contains only a Series elements with [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] values. In this case, the values for the [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] will be updated. Note that it is not permissible to update data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] using partial keys (outside of those associated with defined groups). In order to update an [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]], a full key must always be provided even if the message format does not require this.

10.2	1349	Both the generic and the structure-specific data messages allow for incremental deletion of data. This purpose is noted in the action for the [[data set>>doc:sdmx:Glossary.Data set.WebHome]], which is either inherited from the header of the data message or explicitly stated at the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] (% style="color:#e74c3c" %)level(%%).

10.2	1351	A [[dataset>>doc:sdmx:Glossary.Data set.WebHome]] with an action of Delete is assumed to be an incremental deletion. The deletion is assumed to take place of the lowest (% style="color:#e74c3c" %)level(%%) of detail provided in the message. For example, if a delete message is sent with only a [[data set>>doc:sdmx:Glossary.Data set.WebHome]] element, the entire [[data set>>doc:sdmx:Glossary.Data set.WebHome]] will be deleted. On the other hand, if that [[data set>>doc:sdmx:Glossary.Data set.WebHome]] contains a data [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]], only that data [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] value will be deleted. This same dynamic continues through the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]]. A [[data set>>doc:sdmx:Glossary.Data set.WebHome]] containing only a series with no data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] or observations will result in that entire series (all observations and data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]) being deleted. If the series contains data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]], only the supplied data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] for that series will be deleted. Finally, if a series contains observations, then only the specified observations will be deleted. If an entire observation is to be deleted (value and data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]), only the observation [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] should be provided. If only the [[observation value>>doc:sdmx:Glossary.Observation value.WebHome]] or particular data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] are to be deleted, then these should be specified for the observation. Note that a group can only be used to delete the data [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] associated with it. Although the format might not require it, a full key must be provided to delete a series or observation. It is not permissible to wild card a key in order to delete more than one series or observation. Finally, to delete a data [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] or [[observation value>>doc:sdmx:Glossary.Observation value.WebHome]] it is recommended that the value to be deleted be supplied; however, it is only required that any valid value be provided.
