7 The structures that are an arrangement of objects into hierarchies or lists based on characteristics, and which are maintained as a group inherit from //ItemScheme//. These concrete classes are:
8
9 Codelist
10 ConceptScheme
11 CategoryScheme
12 AgencyScheme, DataProviderScheme, MetadataProviderScheme, DataConsumerScheme, OrganisationUnitScheme, which all inherit from the abstract class //OrganisationScheme//
13 ReportingTaxonomy
14 TransformationScheme
15 RulesetScheme
16 UserDefinedOperatorScheme
17 NamePersonalisationScheme
18 CustomTypeScheme
19 VtlMappingScheme
20
21 Note that the VTL related schemes (the last 6 of the above list) are detailed in a dedicated section below (section 15).

38
39 The Codelist inherits from the //ItemScheme// and therefore has the following attributes:
40
41 id
42 uri
43 urn
44 version
45 validFrom
46 validTo
47 isExternalReference
48 serviceURL
49 structureURL
50 isPartial
51
52 The Code inherits from //Item// and has the following attributes:
53
54 id
55 uri
56 urn
57
58 Both Codelist and Code have the association to InternationalString to support a multilingual name, an optional multi-lingual description, and an association to Annotation to support notes (not shown).
59
60 Through the inheritance the Codelist comprise one or more Codes, and the Code itself can have one or more child Codes in the (inherited) hierarchy association. Note that a child Code can have only one parent Code in this association. A more complex Hierarhcy, which allows multiple parents is described later.
61
62 A partial Codelist (where isPartial is set to 'true') is identical to a Codelist and contains the Code and associated names and descriptions, just as in a normal Codelist. However, its content is a subset of the full Codelist. The way this works is described in section 3.5.3.1 on
63
64 //ItemScheme//.

90
91 A Codelist may extend other Codelists via the CodelistExtension class. The latter, via the sequence, indicates the order of precedence of the extended Codelists for conflict resolution of Codes. Besides that, the prefix property is used to ensure uniqueness of inherited Codes in the extending^^[[(% class="wikiinternallink wikiinternallink wikiinternallink wikiinternallink" %)^^2^^>>path:#sdfootnote2sym||name="sdfootnote2anc"]](%%)^^ Codelist in case conflicting Codes 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 from the extended Codelists.
92
93 The code selection classes may have MemberValues in order to specify the subset of the Codes that should be included or excluded from the extended Codelist. A MemberValue may have a value that corresponds to a ,,Code,,, including its children ,,Code,,s (via the ,,cascadeValues,, property), or even include instances of the wildcard character ‘%’ in order to point to a set of ,,Code,,s with common parts in their identifiers.

128 ==== 4.3.4.1 Narrative ====
129
130 A //GeoCodelist// is a specialisation of Codelist that includes geospatial information, by comprising a set of special Codes, i.e., //GeoRefCode//s. A //GeoCodelist// may be implemented by any of the two following classes, via the geoType property:
131
132 GeographicCodelist
133
134 GeoGridCodelist
135
136 The former, i.e., GeographicCodelist, comprises a set of GeoFeatureSetCodes, by adding a value in the Code that follows a pattern to represent a geo feature set.
137
138 The latter, i.e., GeoGridCodelist, comprises a set of GridCodes, which are related to the gridDefinition specified in the GeoGridCodelist.

183
184 ValueItem inherits from //EnumeratedItem//, which adds an id, with relaxed constraints, to the former.
185
186 Through the inheritance from //NameableArtefact// the ValueList has the association to InternationalString to support a multi-lingual name, an optional multi-lingual description, and an association to Annotation to support notes (not shown). Similarly, the ValueItem, inherits the association to InternationalString and to the Annotation from the //EnumeratedItem//.
187
188 The ValueList can have one or more ValueItems.

216
217 id uri urn
218
219 Through the inheritance from //NameableArtefact// both ConceptScheme and Concept have the association to InternationalString to support a multi-lingual name, an optional multilingual description, and an association to Annotation to support notes (not shown).
220
221 Through the inheritance from //ItemScheme// the ConceptScheme comprise one or more Concepts, and the Concept itself can have one or more child Concepts in the (inherited) hierarchy association. Note that a child Concept can have only one parent Concept in this association.
222
223 A partial ConceptScheme (where isPartial is set to “true”) is identical to a ConceptScheme and contains the Concept and associated names and descriptions, just as in a normal ConceptScheme. However, its content is a subset of the full ConceptScheme. The way this works is described in section 3.5.3.1 on ItemScheme.

232
233 ==== 4.5.4.1 Narrative ====
234
235 The ConceptScheme can have one or more Concepts. A Concept can have zero or more child Concepts, thus supporting a hierarchy of Concepts. Note that a child Concept can have only one parent Concept in this association. The purpose of the hierarchy is to relate concepts that have a semantic relationship: for example, a Reporting_Country and Vis_a_Vis_Country may both have Country as a parent concept, or a CONTACT may have a PRIMARY_CONTACT as a child concept. It is not the purpose of such schemes to define reporting structures: these reporting structures are defined in the MetadataStructureDefinition.
236
237 The Concept can be associated with a coreRepresentation. The coreRepresentation is the specification of the format and value domain of the Concept when used on a structure like a DataStructureDefinition or a MetadataStructureDefinition, unless the specification of the Representation is overridden in the relevant structure definition. In a hierarchical ConceptScheme the Representation is inherited from the parent Concept unless overridden at the level of the child Concept.
238
239 The Representation is documented in more detail in the section on the SDMX Base.
240
241 The Concept may be related to a concept described in terms of the ISO/IEC 11179 standard. The ISOConceptReference identifies this concept and concept scheme in which it is contained.

266
267 === 4.6.1 Context ===
268
269 This package defines the structure that supports the definition of and relationships between categories in a category scheme. It is similar to the package for concept scheme. An example of a category scheme is one which categorises data – sometimes known as a subject matter domain scheme or a data category scheme. Importantly, as will be seen later, the individual nodes in the scheme (the “categories”) can be associated to any set of IdentiableArtefacts in a Categorisation.

278
279 ==== 4.6.3.1 Narrative ====
280
281 The categories are modelled as a hierarchical //ItemScheme//. The CategoryScheme inherits from the //ItemScheme// and has the following attributes:
282
283 id uri urn version validFrom validTo isExternalReference structureURL serviceURL isPartial
284
285 Category inherits from //Item// and has the following attributes:
286
287 id uri urn
288
289 Both CategoryScheme and Category have the association to InternationalString to support a multi-lingual name, an optional multi-lingual description, and an association to Annotation to support notes (not shown on the model).
290
291 Through the inheritance the CategoryScheme comprise one or more Categorys, and the Category itself can have one or more child Category in the (inherited) hierarchy association. Note that a child Category can have only one parent Category in this association.
292
293 A partial CategoryScheme (where isPartial is set to “true”) is identical to a CategoryScheme and contains the Category 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 on ItemScheme.

300
301 The CategoryScheme can have one or more Categorys. The Category is Identifiable and has identity information. A Category can have zero or more child Categorys, thus supporting a hierarchy of Categorys. Any IdentifiableArtefact can be +categorisedBy a Category. This is achieved by means of a Categorisation. Each Categorisation can associate one IdentifiableArtefact with one Category. Multiple Categorisations can be used to build a set of IdentifiableArtefacts that are +categorisedBy the same Category. Note that there is no navigation (i.e. no embedded reference) to the Categorisation from the Category. From an implementation perspective this is necessary as Categorisation has no affect on the versioning of either the Category or the IdentifiableArtefact.

338
339 The //OrganisationScheme// is abstract. It contains //Organisation// which is also abstract. The //Organisation// can have child //Organisation//.
340
341 The //OrganisationScheme// can be one of five types:
342
343 1. AgencyScheme – contains Agency which is restricted to a flat list of agencies (i.e., there is no hierarchy). Note that the SDMX system of (Maintenance) Agency can be hierarchic and this is explained in more detail in the SDMX Standards Section 6 “Technical Notes”.
344 1. DataProviderScheme – contains DataProvider which is restricted to a flat list of agencies (i.e., there is no hierarchy).
345 1. MetadataProviderScheme – contains MetadataProvider which is restricted to a flat list of agencies (i.e., there is no hierarchy).
346 1. DataConsumerScheme – contains DataConsumer which is restricted to a flat list of agencies (i.e., there is no hierarchy).
347 1. OrganisationUnitScheme – contains OrganisationUnit which does inherit the /hierarchy association from Organisation.
348
349 Reference metadata can be attached to the //Organisation// by means of the metadata attachment mechanism. This mechanism is explained in the Reference Metadata section of this document (see section 7). This means that the model does not specify the specific reference metadata that can be attached to a DataProvider, MetadataProvider, DataConsumer, OrganisationUnit or Agency, except for limited Contact information.
350
351 A partial //OrganisationScheme// (where isPartial is set to “true”) is identical to an //OrganisationScheme// and contains the //Organisation// and associated names and descriptions, just as in a normal //OrganisationScheme//. However, its content is a subset of the full //OrganisationScheme//. The way this works is described in section 3.5.3.1 on //ItemScheme//.

452 ==== 4.8.2.1 Narrative ====
453
454 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.
455
456 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, or Metadataflow, and one or more //Structure//, which itself can be one of DataStructureDefinition or MetadataStructureDefinition. It is expected that within a specific ReportingTaxonomy each Category that is linked in this way will be linked to the same class (e.g. all Category in the scheme will link to a Dataflow). 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:
457
458 Section 1
459
460 1. linked to Datafow_1
461 1. linked to Datafow_2
462
463 Section 2
464
465 1. linked to Datafow_3
466 1. linked to Datafow_4
467
468 Here, the nodes of Section 1 and Section 2 would not be linked to Dataflow but the other would be linked to a Dataflow (and hence the DataStructureDefinition).
469
470 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 on //ItemScheme//.
