36.3	49	Through the inheritance the [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] comprise one or more [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]], and the [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] itself can have one or more child [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] in the (inherited) [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] association. Note that a child [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] can have only one parent [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] in this association. A more complex Hierarhcy, which allows multiple parents is described later.

The latter, via the sequence, indicates the order of precedence of the extended [[Codelists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] for conflict resolution of [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]]. Besides that, the prefix property is used to ensure uniqueness of inherited [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] in the extending{{footnote}}The Codelist that extends 0..* Codelists is the 'extending' Codelist, while the Codelist(s) that are inherited is/are the 'extended' Codelist(s).{{/footnote}} [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] in case conflicting [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] must be included in the latter. Each CodelistExtension association may include one InclusiveCodeSelection or one ExclusiveCodeSelection; those allow including or excluding a specific selection of [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] from the extended [[Codelists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]].
1.1	77
36.5	78	The [[code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] selection classes may have MemberValues in order to specify the subset of the [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] that should be included or excluded from the extended [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]]. A MemberValue may have a value that corresponds to a [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]], including its children [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] (via the cascadeValues property), or even include instances of the wildcard character ‘%’ in order to point to a set of [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] with common parts in their identifiers.

1.1	111
36.5	112	A //GeoCodelist// is a specialisation of [[Codelist>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] that includes geospatial information, by comprising a set of special [[Codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]], i.e., //GeoRefCode//s. A //GeoCodelist// may be implemented by any of the two following classes, via the geoType property:
1.1	113
36.2	114	GeographicCodelist
1.1	115
36.2	116	GeoGridCodelist
1.1	117
36.5	118	The former, i.e., GeographicCodelist, comprises a set of GeoFeatureSetCodes, by adding a value in the [[Code>>doc:sdmx:Glossary 2\.1.Code.WebHome]] that follows a pattern to represent a geo feature set.
1.1	119
36.2	120	The latter, i.e., GeoGridCodelist, comprises a set of GridCodes, which are related to the gridDefinition specified in the GeoGridCodelist.

1.1	234
36.10	235	The ConceptScheme can have one or more [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. A [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can have zero or more child [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], thus supporting a [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] of [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. Note that a child [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can have only one parent [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] in this association. The purpose of the [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] is to relate [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] that have a semantic relationship: for example, a Reporting_Country and Vis_a_Vis_Country may both have Country as a parent [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], or a [[CONTACT>>doc:sdmx:Glossary 2\.1.Contact.WebHome]] may have a PRIMARY_CONTACT as a child [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. It is not the purpose of such schemes to define reporting structures: these reporting structures are defined in the MetadataStructureDefinition.
1.1	236
36.10	237	The [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can be associated with a coreRepresentation. The coreRepresentation is the specification of the format and value domain of the [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] when used on a structure like a DataStructureDefinition or a MetadataStructureDefinition, unless the specification of the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is overridden in the relevant structure definition. In a hierarchical ConceptScheme the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is inherited from the parent [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] unless overridden at the [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] of the child [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]].
1.1	238
36.10	239	The [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is documented in more detail in the section on the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Base.
1.1	240
36.10	241	The [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] may be related to a [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] described in terms of the ISO/IEC 11179 standard. The ISOConceptReference identifies this [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] and [[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] in which it is contained.

It is similar to the package for [[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]]. An example of a [[category scheme>>doc:sdmx:Glossary 2\.1.Category scheme.WebHome]] is one which categorises data – sometimes known as a subject matter domain scheme or a data [[category scheme>>doc:sdmx:Glossary 2\.1.Category scheme.WebHome]]. Importantly, as will be seen later, the individual nodes in the scheme (the “[[categories>>doc:sdmx:Glossary 2\.1.Category.WebHome]]”) can be associated to any set of IdentiableArtefacts in a [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]].

1.1	280
36.11	281	The [[categories>>doc:sdmx:Glossary 2\.1.Category.WebHome]] are modelled as a hierarchical //ItemScheme//. The CategoryScheme inherits from the //ItemScheme// and has the following [[attributes>>doc:sdmx:Glossary 2\.1.Attribute.WebHome]]:

1.1	295
36.2	296	id
	297	uri
	298	urn
1.1	299
36.11	300	Both CategoryScheme and [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] have the association to InternationalString to support a multi-lingual name, an optional multi-lingual description, and an association to [[Annotation>>doc:sdmx:Glossary 2\.1.Annotation.WebHome]] to support notes (not shown on the model).
1.1	301
36.11	302	Through the inheritance the CategoryScheme comprise one or more [[Categorys>>doc:sdmx:Glossary 2\.1.Category.WebHome]], and the [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] itself can have one or more child [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] in the (inherited) [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] association. Note that a child [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] can have only one parent [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] in this association.
1.1	303
36.11	304	A partial CategoryScheme (where isPartial is set to “true”) is identical to a CategoryScheme and contains the [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] and associated names and descriptions, just as in a normal CategoryScheme. However, its content is a subset of the full CategoryScheme. The way this works is described in section [[3.5.3.1>>doc:Methodology.SDMX 3\.1 Standards\. Section 2\. Information model.3 SDMX Base Package.WebHome\|\|anchor="H3.5.3.1Narrative"]] on ItemScheme.

1.1	311
36.11	312	The CategoryScheme can have one or more [[Categorys>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. The [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] is Identifiable and has identity information. A [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] can have zero or more child [[Categorys>>doc:sdmx:Glossary 2\.1.Category.WebHome]], thus supporting a [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] of [[Categorys>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. Any IdentifiableArtefact can be +categorisedBy a [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. This is achieved by means of a [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]]. Each [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]] can associate one IdentifiableArtefact with one [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. Multiple [[Categorisations>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]] can be used to build a set of IdentifiableArtefacts that are +categorisedBy the same [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. Note that there is no navigation (i.e. no embedded reference) to the [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]] from the [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]]. From an implementation perspective this is necessary as [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]] has no effect on the versioning of either the CategoryScheme or the IdentifiableArtefact.

1.1	348
36.2	349	The //OrganisationScheme// can be one of five types:
1.1	350
36.11	351	1. AgencyScheme – contains Agency which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]]). Note that the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] system of (Maintenance) Agency can be hierarchic and this is explained in more detail in the [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] Standards Section 6 “Technical Notes”.
	352	1. DataProviderScheme – contains DataProvider which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]]).
	353	1. MetadataProviderScheme – contains MetadataProvider which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]]).
	354	1. DataConsumerScheme – contains DataConsumer which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]]).
	355	1. (% style="background-color:#d35400" %)OrganisationUnitScheme(%%) – contains OrganisationUnit which does inherit the /[[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] association from Organisation.
1.1	356
36.11	357	[[Reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] can be attached to the //Organisation// by means of the metadata attachment mechanism. This mechanism is explained in the [[Reference Metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] section of this document (see section 7). This means that the model does not specify the specific [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] that can be attached to a DataProvider, MetadataProvider, DataConsumer, OrganisationUnit or Agency, except for limited [[Contact>>doc:sdmx:Glossary 2\.1.Contact.WebHome]] information.

4.1	441	==== 4.8.2.1 Narrative ====
1.1	442
36.2	443	In some data reporting environments, and in particular those in primary reporting, a report may comprise a variety of heterogeneous data, each described by a different //Structure//. Equally, a specific disseminated or published report may also comprise a variety of heterogeneous data. The definition of the set of linked sub reports is supported by the ReportingTaxonomy.
1.1	444
37.1	445	The ReportingTaxonomy is a specialised form of //ItemScheme//. Each ReportingCategory of the ReportingTaxonomy can link to one or more //StructureUsage// which itself can be one of [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]], or [[Metadataflow>>doc:sdmx:Glossary 2\.1.Metadataflow.WebHome]], and one or more //Structure//, which itself can be one of DataStructureDefinition or MetadataStructureDefinition. It is expected that within a specific ReportingTaxonomy each [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] that is linked in this way will be linked to the same class (e.g. all [[Category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] in the scheme will link to a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]]). Note that a ReportingCategory can have child ReportingCategory and in this way it is possible to define a hierarchical ReportingTaxonomy. It is possible in this taxonomy that some ReportingCategory are defined just to give a reporting structure. For instance:
1.1	446
	447	Section 1
	448
	449	1. linked to Datafow_1
	450	1. linked to Datafow_2
	451
	452	Section 2
	453
	454	1. linked to Datafow_3
	455	1. linked to Datafow_4
	456
37.1	457	Here, the nodes of Section 1 and Section 2 would not be linked to [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] but the other would be linked to a [[Dataflow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] (and hence the DataStructureDefinition).
1.1	458
36.2	459	A partial ReportingTaxonomy (where isPartial is set to “true”) is identical to a ReportingTaxonomy and contains the ReportingCategory and associated names and descriptions, just as in a normal ReportingTaxonomy. However, its content is a sub set of the full ReportingTaxonomy The way this works is described in section [[3.5.3.1>>doc:Methodology.SDMX 3\.1 Standards\. Section 2\.
