294		-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 effect on the versioning of either the CategoryScheme or the IdentifiableArtefact.

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.
