5 +== 4.1 Introduction ==
6 +
7 +The structures that are an arrangement of objects into [[hierarchies>>doc:xwiki:Glossary.Hierarchy.WebHome]] 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>>doc:xwiki:Glossary.Validation and transformation language.WebHome]] related schemes (the last 6 of the above list) are detailed in a dedicated section below (section 15).
22 +
23 +== 4.2 Inheritance View ==
24 +
25 +The inheritance and relationship views are shown together in each of the diagrams in the specific sections below.
26 +
27 +== 4.3 Codelist ==

38 +
39 +The Codelist inherits from the //ItemScheme// and therefore has the following [[attributes>>doc:xwiki:Glossary.Attribute.WebHome]]:

52 +The [[Code>>doc:xwiki:Glossary.Code.WebHome]] inherits from //Item// and has the following [[attributes>>doc:xwiki:Glossary.Attribute.WebHome]]:
53 +
54 +id
55 +uri
56 +urn
57 +
58 +Both Codelist and [[Code>>doc:xwiki:Glossary.Code.WebHome]] have the association to InternationalString to support a multilingual name, an optional multi-lingual description, and an association to [[Annotation>>doc:xwiki:Glossary.Annotation.WebHome]] to support notes (not shown).
59 +
60 +Through the inheritance the Codelist comprise one or more [[Codes>>doc:xwiki:Glossary.Code.WebHome]], and the [[Code>>doc:xwiki:Glossary.Code.WebHome]] itself can have one or more child [[Codes>>doc:xwiki:Glossary.Code.WebHome]] in the (inherited) [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] association. Note that a child [[Code>>doc:xwiki:Glossary.Code.WebHome]] can have only one parent [[Code>>doc:xwiki:Glossary.Code.WebHome]] 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>>doc:xwiki:Glossary.Code.WebHome]] 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 //ItemScheme//.

86 +
87 +==== 4.3.3.1 Narrative ====
88 +
89 +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>>doc:xwiki:Glossary.Code.WebHome]]. Besides that, the prefix property is used to ensure uniqueness of inherited [[Codes>>doc:xwiki:Glossary.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 in case conflicting [[Codes>>doc:xwiki:Glossary.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:xwiki:Glossary.Code.WebHome]] from the extended Codelists.
90 +
91 +The [[code>>doc:xwiki:Glossary.Code.WebHome]] selection classes may have MemberValues in order to specify the subset of the [[Codes>>doc:xwiki:Glossary.Code.WebHome]] that should be included or excluded from the extended Codelist. A MemberValue may have a value that corresponds to a [[Code>>doc:xwiki:Glossary.Code.WebHome]], including its children [[Codes>>doc:xwiki:Glossary.Code.WebHome]] (via the cascadeValues property), or even include instances of the wildcard character ‘%’ in order to point to a set of [[Codes>>doc:xwiki:Glossary.Code.WebHome]] with common parts in their identifiers.

125 +
126 +A //GeoCodelist// is a specialisation of Codelist that includes geospatial information, by comprising a set of special [[Codes>>doc:xwiki:Glossary.Code.WebHome]], i.e., //GeoRefCode//s. A //GeoCodelist// may be implemented by any of the two following classes, via the geoType property:
127 +
128 +GeographicCodelist
129 +GeoGridCodelist
130 +
131 +The former, i.e., GeographicCodelist, comprises a set of GeoFeatureSetCodes, by adding a value in the [[Code>>doc:xwiki:Glossary.Code.WebHome]] that follows a pattern to represent a geo feature set.
132 +

250 +
251 +The ConceptScheme can have one or more (% style="color:#2ecc71" %)Concepts(%%). A (% style="color:#2ecc71" %)Concept(%%) can have zero or more child (% style="color:#2ecc71" %)Concepts(%%), thus supporting a [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] of (% style="color:#2ecc71" %)Concepts(%%). Note that a child (% style="color:#2ecc71" %)Concept(%%) can have only one parent (% style="color:#2ecc71" %)Concept(%%) in this association. The purpose of the [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] is to relate (% style="color:#2ecc71" %)concepts(%%) that have a semantic relationship: for example, a Reporting_Country and Vis_a_Vis_Country may both have Country as a parent (% style="color:#2ecc71" %)concept(%%), or a (% style="color:#2ecc71" %)CONTACT(%%) may have a PRIMARY_CONTACT as a child (% style="color:#2ecc71" %)concept(%%). It is not the purpose of such schemes to define reporting structures: these reporting structures are defined in the MetadataStructureDefinition.
252 +
253 +The (% style="color:#2ecc71" %)Concept(%%) can be associated with a coreRepresentation. The coreRepresentation is the specification of the format and value domain of the (% style="color:#2ecc71" %)Concept(%%) when used on a structure like a DataStructureDefinition or a MetadataStructureDefinition, unless the specification of the [[Representation>>doc:xwiki:Glossary.Representation.WebHome]] is overridden in the relevant structure definition. In a hierarchical ConceptScheme the [[Representation>>doc:xwiki:Glossary.Representation.WebHome]] is inherited from the parent (% style="color:#2ecc71" %)Concept(%%) unless overridden at the (% style="color:#2ecc71" %)level(%%) of the child (% style="color:#2ecc71" %)Concept(%%).
254 +
255 +The [[Representation>>doc:xwiki:Glossary.Representation.WebHome]] is documented in more detail in the section on the [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] Base.
256 +
257 +The (% style="color:#2ecc71" %)Concept(%%) may be related to a (% style="color:#2ecc71" %)concept(%%) described in terms of the ISO/IEC 11179 standard.

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

Note that a child [[Category>>doc:xwiki:Glossary.Category.WebHome]] can have only one parent [[Category>>doc:xwiki:Glossary.Category.WebHome]] in this association.
317 +
318 +A partial CategoryScheme (where isPartial is set to “true”) is identical to a CategoryScheme and contains the [[Category>>doc:xwiki:Glossary.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 on ItemScheme.

325 +
326 +The CategoryScheme can have one or more [[Categorys>>doc:xwiki:Glossary.Category.WebHome]]. The [[Category>>doc:xwiki:Glossary.Category.WebHome]] is Identifiable and has identity information. A [[Category>>doc:xwiki:Glossary.Category.WebHome]] can have zero or more child [[Categorys>>doc:xwiki:Glossary.Category.WebHome]], thus supporting a [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] of [[Categorys>>doc:xwiki:Glossary.Category.WebHome]]. Any IdentifiableArtefact can be +categorisedBy a [[Category>>doc:xwiki:Glossary.Category.WebHome]]. This is achieved by means of a Categorisation. Each Categorisation can associate one IdentifiableArtefact with one [[Category>>doc:xwiki:Glossary.Category.WebHome]]. Multiple Categorisations can be used to build a set of IdentifiableArtefacts that are +categorisedBy the same [[Category>>doc:xwiki:Glossary.Category.WebHome]]. Note that there is no navigation (i.e. no embedded reference) to the Categorisation from the [[Category>>doc:xwiki:Glossary.Category.WebHome]]. From an implementation perspective this is necessary as Categorisation has no affect on the versioning of either the [[Category>>doc:xwiki:Glossary.Category.WebHome]] or the IdentifiableArtefact.

359 +==== 4.7.2.1 Narrative ====
360 +
361 +The //OrganisationScheme// is abstract. It contains //Organisation// which is also abstract. The //Organisation// can have child //Organisation//.
362 +
363 +The //OrganisationScheme// can be one of five types:
364 +
365 +1. AgencyScheme – contains Agency which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]]). Note that the [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] system of (Maintenance) Agency can be hierarchic and this is explained in more detail in the [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] Standards Section 6 “Technical Notes”.
366 +1. DataProviderScheme – contains DataProvider which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]]).
367 +1. MetadataProviderScheme – contains MetadataProvider which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]]).
368 +1. DataConsumerScheme – contains DataConsumer which is restricted to a flat list of agencies (i.e., there is no [[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]]).
369 +1. OrganisationUnitScheme – contains OrganisationUnit which does inherit the /[[hierarchy>>doc:xwiki:Glossary.Hierarchy.WebHome]] association from Organisation.
370 +
371 +[[Reference metadata>>doc:xwiki:Glossary.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:xwiki:Glossary.Reference metadata.WebHome]] section of this document (see section 7). This means that the model does not specify the specific [[reference metadata>>doc:xwiki:Glossary.Reference metadata.WebHome]] that can be attached to a DataProvider, MetadataProvider, DataConsumer, OrganisationUnit or Agency, except for limited (% style="color:#2ecc71" %)Contact(%%) information.
372 +
373 +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//.

451 +**Figure 26: Class diagram of the Reporting Taxonomy**
452 +
453 +=== 4.8.2 Explanation of the Diagram ===
454 +
455 +==== 4.8.2.1 Narrative ====
456 +
457 +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.
458 +
459 +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:xwiki:Glossary.Dataflow.WebHome]], or [[Metadataflow>>doc:xwiki:Glossary.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:xwiki:Glossary.Category.WebHome]] that is linked in this way will be linked to the same class (e.g. all [[Category>>doc:xwiki:Glossary.Category.WebHome]] in the scheme will link to a [[Dataflow>>doc:xwiki:Glossary.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:
460 +
461 +Section 1
462 +
463 +1. linked to Datafow_1
464 +1. linked to Datafow_2
465 +
466 +Section 2
467 +
468 +1. linked to Datafow_3
469 +1. linked to Datafow_4
470 +
471 +Here, the nodes of Section 1 and Section 2 would not be linked to [[Dataflow>>doc:xwiki:Glossary.Dataflow.WebHome]] but the other would be linked to a [[Dataflow>>doc:xwiki:Glossary.Dataflow.WebHome]] (and hence the DataStructureDefinition).
472 +
473 +A partial ReportingTaxonomy (where isPartial is set to “true”) is identical to a ReportingTaxonomy and contains the ReportingCategory and associated
474 +
475 +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//.
