36		-//**DataSetType:**// DataSetType is the abstract type which defines the base structure for any data structure definition specific data set. A derived data set type will be created that is specific to a data structure definition and the details of the organisation of the data (i.e. which dimension is the observation dimension). Data is organised into either a collection of series (grouped observations) or a collection of un-grouped observations. The derived data set type will restrict this choice to be either grouped or un-grouped observations. If this dimension is "AllDimensions" then the derived data set type must consist of a collection of un-grouped observations; otherwise, the data set will contain a collection of series with the observations in the series disambiguated by the specified dimension at the observation level. This data set is capable of containing data (observed values) and/or documentation (data and metadata attribute values) and can be used for incremental updates 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 specific data will have a consistent structure. The group, series, 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 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 specific schema.

75		-//**GroupType:**// GroupType is the abstract type which defines a structure which is used to communicate attribute values for a group defined in a data structure definition. The group can consist of either a subset of the dimensions defined by the data structure definition, or an association to an attachment constraint, which in turn defines key sets to which attributes can be attached. In the case that the group is based on an attachment 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 constraint and apply the values provided for the attributes appropriately. Data structure definition schemas will drive types based on this for each group defined in the data structure definition. Both the dimension values which make up the key (if applicable) and the attribute values associated with the group will be represented with XML attributes. 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 are explicit. The XML attributes will be given a name based on the attribute's identifier. These XML attributes will be unqualified (meaning they do not have a namespace associated with them). The dimension XML attributes will be required while the attribute XML attributes will be optional. To allow for generic processing, it is required that the only unqualified XML attributes in the derived group type be for the group dimensions and data or metadata attributes declared in the data structure definition. If additional attributes 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 dimension or attribute.

128		-***CompType*:** CompType is the abstract base for any component value (e.g. a data or metadata attribute, or a measure) that cannot be represented as an XML attribute. For example, a repeated value, a text value in multiple languages, or a value with structured text (XHTML) cannot be expressed as an XML attribute. This type is meant to be restricted based on the component to restrict the cardinality and type of its Value element to conform to the component definition. The type of the value element should be restricted to common:SimpleValueType, common:TextValueType, or common:StructuredValueType. In addition, the id attribute should be restricted to be a fixed value with the component identifier. This restricted type based on the component can then be used on Comp elements by using the xsi:type to state the component being expressed and refine the contents of the element to the values allowed by the component.

152		-***ObsType*:** ObsType is the abstract type which defines the structure of a grouped or un-grouped observation. The observation must be provided a key, which is either a value for the dimension which is declared to be at the observation level if the observation is grouped, or a full set of values for all dimensions in the data structure definition 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 value in a series). The observation can contain an observed value and/or attribute values. Data structure definition schemas will derive a type or types based on this that is specific to the data structure definition and the variation of the format being expressed in the schema. The dimension value(s) which make up the key and the data and metadata attribute values associated with the key dimension(s) or the primary measure will be represented with XML attributes. 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 are explicit. The XML attributes will be given a name based on the attribute's identifier. These XML attributes will be unqualified (meaning they do not have a namespace associated with them). The dimension XML attribute(s) will be required while the attribute XML attributes will be optional. To allow for generic processing, it is required that the only unqualified XML attributes in the derived observation type be for the observation dimension(s) and attributes declared in the data structure definition. If additional attributes 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 dimension or attribute.

361	361	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:
362	362
363	363	**Schema:** Refers to the format specific schema in general, and in particular the root xs:schema element of that schema file.
364	364
365		-**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) and possibly a substitution group (substitutionGroup attribute).
	382	+**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]]).
366	366
367		-**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) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
	384	+**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]]).
368	368
369	369	**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.
370	370
371		-**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) and may also specify a minimum and maximum occurrence (minOccurs and maxOccurs attribute).
	388	+**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).

372	372
373		-**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) and may be made abstract (via the abstract attribute’s boolean value).
	390	+**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).
374	374
375		-**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.
	392	+**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.
376	376
377	377	**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.
378	378
379	379	**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.
380	380
381		-**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). This is defined in an \<xs:unique\> element and has content of an \<xs:selector\> and multiple \<xs:field\> elements. The selector designates the descendants that must be unique (with an xpath attribute) and the field specifies which property of the selected element must be unique (also with an xpath attribute)
	398	+**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]]).

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]])
382	382
383		-**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).
	400	+**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]]).
384	384
385		-**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).
	402	+**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]]).
386	386
387		-**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).
	404	+**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]]).
388	388
389		-**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).
	406	+**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]]).
390	390
391		-**Facet:** 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 is contained in a value attribute of the particular element.
	408	+**[[Facet>>doc:sdmx:Glossary.Facet.WebHome]]:** Refers to a single detail of a simple type restriction.

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.
392	392
393		-**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) and documentation (in xs:documentation elements contained in an xs:annotation element).
	410	+**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).
394	394
395		-**XML Attribute:** Refers to the definition of an XML attribute for a complex type (i.e. and xs:attribute element in a xs:complexType element). An attribute must define a name and type (name and type attributes) and may also specify a usage (use attribute).
	412	+**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).

897	897
898	898	Reference metadata defined by a Metadataflow or a MetadataProvisionAgreement are exchanged within reference metadatasets, which are maintainable and thus for actions behave like structural metadata (artefacts): When interacting with SDMX 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” may contain only partial languages, and thus should be marked with its *isPartialLanguage* property set to true. Submitting such a partial metadataset to update an SDMX storage system will only add or update the included languages but not change other languages.
