7 The [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] metamodel allows metadata:
8
9 1. To be exchanged without the need to embed it within the object that it is describing.
10 1. To be stored separately from the object that it describes, yet be linked to it (for example, an organisation has a [[metadata repository>>doc:sdmx:Glossary.Metadata repository.WebHome]] which supports the dissemination of metadata resulting from metadata requests generated by systems or services that have access to the object for which the metadata pertains. This is common in web dissemination where additional metadata is available for viewing (and eventually downloading) by clicking on an “information” icon next to the object to which the metadata is attached).
11 1. To be indexed to aid searching (example: a registry service can process a metadata report and extract structural information that allows it to catalogue the metadata in a way that will enable users to query for it).
12 1. To be reported according to a defined structure.
13
14 In order to achieve this, the following structures are modelled:
15
16 * [[metadata structure definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]] which has the following [[components>>doc:sdmx:Glossary.Component.WebHome]]:
17 ** the object types to which the metadata are to be associated (attached)
18 ** the [[components>>doc:sdmx:Glossary.Component.WebHome]] that, together, comprise a unique key of the object type to which the metadata are to be associated
19 ** the reporting structure comprising the metadata [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] that can be attached to the various object types (these [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] can be structured in a [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]]), together with any (% style="color:#e74c3c" %)constraints(%%) that may apply (e.g. association to a [[code list>>doc:sdmx:Glossary.Code list.WebHome]] that contains valid values for the [[attribute>>doc:sdmx:Glossary.Attribute.WebHome]] when reported in a [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]])
20 * the [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]], which contains reported metadata

25
26 As with the [[Data Structure Definition>>doc:sdmx:Glossary.Data structure definition.WebHome]] Structure, many of the constructs in this layer of the model inherit from the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Base layer. Therefore, it is necessary to study both the inheritance and the relationship diagrams to understand the functionality of individual packages. The diagram below shows the full inheritance tree for the classes concerned with the MetadataStructureDefinition and the MetadataSet.
27
28 There are very few additional classes in the MetadataStructureDefinition package that do not themselves inherit from classes in the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Base. In other words, the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Base gives most of the structure of this sub model both in terms of associations and in terms of [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]. The relationship diagrams shown in this section show clearly when these associations are inherited from the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] Base (see the Appendix “A Short Guide to UML in the [[SDMX Information Model>>doc:sdmx:Glossary.SDMX Information Model.WebHome]]” to see the diagrammatic notation used to depict this). It is important to note that [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] base structures used for the MetadataStructureDefinition are the same as those used for the DataStructureDefinition and so, even though the usage is slightly different, the underlying way of defining a MetadataStructureDefinition is similar to that used for defining a DataStructureDefinition.

40 It is important to the understanding of the relationship class diagrams presented in this section to identify the concrete classes that inherit from the abstract classes.
41
42 The concrete classes in this part of the [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] metamodel which require to be maintained by [[Maintenance Agencies>>doc:sdmx:Glossary.Maintenance agency.WebHome]] all inherit from MaintainableArtefact. These are:
43
44 * //StructureUsage// (concrete class is MetadataflowDefinition)
45 * //Structure// (concrete class is MetadataStructureDefinition)
46
47 These classes also inherit the identity and versioning [[facets>>doc:sdmx:Glossary.Facet.WebHome]] of //IdentifiableArtefact, NameableArtefact,// and //VersionableArtefact//.
48
49 A //Structure// contains several lists of [[components>>doc:sdmx:Glossary.Component.WebHome]]. The concrete classes which inherit from //ComponentList// and in themselves are sub [[components>>doc:sdmx:Glossary.Component.WebHome]] of the MetadataStructureDefinition are:
50
51 * MetadataTarget
52 * ReportStructure
53
54 //ComponentList// contains [[Components>>doc:sdmx:Glossary.Component.WebHome]]. The classes that inherit from //[[Component>>doc:sdmx:Glossary.Component.WebHome]]// are:
55
56 * Sub Classes of //TargetObject//
57 * MetadataAttribute

83 ==== 7.3.4.1 Narrative ====
84
85 In brief a MetadataStructureDefinition ([[MSD>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]) defines:
86
87 * The MetadataTarget which defines the [[components>>doc:sdmx:Glossary.Component.WebHome]] (//TargetObject//) and their [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] which are valid for this MetadataStructureDefinition, and which are the metadata target object of one or more ReportStructure
88 * The ReportStructures comprising the MetadataAttributes that can be associated with the object type identified in the referenced MetadataTargets, and hierarchical structure of the [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]]
89
90 The MetadataTarget comprises one or more //TargetObject//s//.// The combination of //TargetObject//s// //identifies a specific object type to which metadata can be attached in a MetadataSet.
91
92 The //TargetObject// is one of the following:
93
94 * DimensionDescriptorValuesTarget - this allows the specification of a full or partial key (as used in a [[dataset>>doc:sdmx:Glossary.Data set.WebHome]]) to be specified in a MetadataSet as the target object
95 * IdentifiableObjectTarget – this defines a specific object type, which can be any IdentifiableArtefact
96 * DataSetTarget – this specifies that the target object is a [[DataSet>>doc:sdmx:Glossary.Data set.WebHome]]
97 * ReportPeriodTarget - this specifies that the report period must be present in the MetadataSet
98 * ConstraintContentTarget – this specifies that target object is the content of an AttachmentConstraint i.e. the part of the [[data set>>doc:sdmx:Glossary.Data set.WebHome]] or [[metadata set>>doc:sdmx:Glossary.Metadata set.WebHome]] identified by the content of an AttachmentConstraint
99
100 The valid content of a //TargetObject// when reported in a MetadataSet is defined in the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]]. This can be an enumerated [[representation>>doc:sdmx:Glossary.Representation.WebHome]] (i.e. a reference to one of the sub clases of ItemScheme – these are Codelist, ConceptScheme, //OrganisationScheme,// CategoryScheme, or ReportingTaxonomy) or nonenumerated.
101
102 Thus a single MetadataStructureDefinition can be defined for a discrete set of related object types. For example, a single definition can be constructed to define the metadata that can be attached to any part of a [[Data Structure Definition>>doc:sdmx:Glossary.Data structure definition.WebHome]], or that can be attached to any [[artefact>>doc:sdmx:Glossary.Artefact.WebHome]] concerned with the reporting of quality metadata (such as [[data provider>>doc:sdmx:Glossary.Data provider.WebHome]] and (data) [[category>>doc:sdmx:Glossary.Category.WebHome]]). The MetadataTarget specifies the identification properties of a specific object type to which metadata can be attached in a MetadataSet. For example, in a DataStructureDefinition the MetadataTarget might be a [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]], and therefore the //TargetObject//s are those that uniquely identify a [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]. This will include both the DataStructureDefinition and he [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]] both of these are an //IdentifiableArtefact //and will use the// //IdentitifableObjectTarget) as both //TargetObject//s are required in order to identify uniquely a [[Dimension>>doc:sdmx:Glossary.Dimension.WebHome]]).
103
104 The ReportStructure comprises a set of MetadataAttributes - these can be defined as a [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]]. Each MetadataAttribute// //identifies a (% style="color:#e74c3c" %)[[Concept>>doc:sdmx:Glossary.Concept.WebHome]](%%) that is reported or disseminated in a MetadataSet (/conceptIdentity) that uses this MetadataStructureDefinition. Different MetadataAttributes in the same ReportStructure can use (% style="color:#e74c3c" %)[[Concepts>>doc:sdmx:Glossary.Concept.WebHome]](%%) from different ConceptSchemes. Note that a MetadataAttribute does not link to a (% style="color:#e74c3c" %)[[Concept>>doc:sdmx:Glossary.Concept.WebHome]](%%) that defines its role in this MetadataStructureDefinition (i.e. the MetadataAttribute does not play a role).
105
106 The MetadataAttribute can be specified as having multiple occurrences and/or specified as being mandatory (minOccurs=1 or more) or conditional (minOccurs=0). A hierarchical ReportStructure can be defined by specifying a [[hierarchy>>doc:sdmx:Glossary.Hierarchy.WebHome]] for a MetadataAttribute.
107
108 The ReportStructure is associated to one or more of the MetadataTargets which specify to which object the MetadataAttributes specified in the ReportStructure are attached when reported in a MetadataSet.
109
110 It can be seen from this that the specification of the object types to which a MetadataAttribute can be attached is indirect: the MetadataAttributes are defined in a ReportStructure which itself is attached to one or more MetadataTarget and the actual object is identified by the //TargetObject//s comprising the MetadataTarget. This gives a flexible mechanism by which the actual object types need not be defined in concrete terms in the model, but are defined dynamically in the MetadataStructureDefinition, in much the same way as the keys to which data observation are “attached” in a DataStructureDefinition. In this way the MetadataStructureDefinition can be used to define any set of MetadataAttributes and any set of object types to which they can be attached.
111
112 Each MetadataAttribute can have a [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] specified (using the /localRepresentation association). If this is not specified in the MetadataStructureDefinition then the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] is taken from that defined for the (% style="color:#e74c3c" %)[[Concept>>doc:sdmx:Glossary.Concept.WebHome]](%%) (the coreRepresentation association).
113
114 The definition of the various types of [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] can be found in the specification of the Base constructs. Note that if the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] is non-enumerated then the association is to the ExtendedFacet (which allows for xhtml as a FacetValueType). If the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] is enumerated then is must use a Codelist.
115
116 The MetadataStructureDefinition is linked to a MetadataflowDefinition. The MetadataflowDefinition does not have any [[attributes>>doc:sdmx:Glossary.Attribute.WebHome]] in addition to those inherited from the Base classes.

193 ==== 7.4.2.1 Narrative ====
194
195 Note that the MetadataSet must conform to the MetadataStructureDefinition associated to the MetadataflowDefinition for which this MetadataSet is an “instance of metadata”. Whilst the model shows the association to the classes of the MetadataStructureDefinition, this is for conceptual purposes to show the link to the MetadataStructureDefinition. In the actual MetadataSet as exchanged there must, of course, be a reference to the MetadataStructureDefinition and the ReportStructure, and optionally a MetadataflowDefinition, but the MetadataStructureDefinition is not necessarily exchanged with the metadata. Therefore, the MetadataStructureDefinition classes are shown in the grey areas, as these are not a part of the MetadataSet itself.
196
197 An organisation playing the role of DataProvider can be responsible for one or more MetadataSet.
198
199 A MetadataSet comprises one or more MetadataReport, each of which must be for the same ReportStructure. It references both a MetadataTarget, defined in the MetadataStructureDefinition, and contains a TargetObjectKey and ReportedAttributes.
200
201 The identified ReportStructure specifies which MetadataAttributes are expected as //ReportedAttribute//s. The identified MetadataTarget specifies the expected content of the TargetObjectKey i.e. it specifies the information required to identify the object for which the //ReportedAttribute//s are reported.
202
203 The TargetObjectValue can be one of:
204
205 * TargetDataKey – this can contain:
206 ** a SeriesKey (set of [[dimension>>doc:sdmx:Glossary.Dimension.WebHome]] values)
207 ** a SeriesKey plus a value or values (giving time range) for the TimeDimension (TimeDimensionValue)
208 ** a value of values for the TimeDimension
209 * TargetIdentifiableObject – this identifies any identifiable object (which includes both Maintainable and Identifiable objects
210 * TargetDataSet – this identifies a [[DataSet>>doc:sdmx:Glossary.Data set.WebHome]]
211 * TargetReportPeriod – this specifies the report period for the Report
212
213 A simple text value for the //ReportedAttribute// uses the //NonEnumeratedAttributeValue //sub class of //ReportedAttribute// whilst a coded value uses the EnumeratedAttributeValue sub class.
214
215 The //NonEnumeratedAttributeValue// can be one of:
216
217 * XHTMLAttributeValue – the content is XHTML
218 * TextAttributeValue – the content is textual and may contain the text in multiple languages
219 * OtherNonEnumeratedAttributeValue – the content is a string value that must conform to the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] specified for the MetadataAttribute in the MetadataStructureDefinition for the relevant ReportStructure
220
221 The EnumeratedAttributeValue contains a value for a [[Code>>doc:sdmx:Glossary.Code.WebHome]] specified as the [[Representation>>doc:sdmx:Glossary.Representation.WebHome]] for the MetadataAttribute in the MetadataStructureDefinition for the relevant ReportStructure.
