ExternalReference entity

ExternalReference entity is an AuthoredReferenceable that describes an external source of information.

  • referenceTitle - Full publication title of the external source.
  • referenceAbstract - Summary of the key messages in the external source.
  • authors - List of authors for the external source.
  • sources - Names of external sources and specific location where this external information can be accessed from. This may be URLs, publisher or retailer information, for example.
  • organization - Identifier of the organization that this resource is from.
  • license - Name of license associated with this external source.
  • copyright - Copyright statement associated with this external source.
  • attribution - Attribution statement to use when consuming this external resource.

ExternalReferenceLink connects another Referenceable to an ExternalReference entity. It allows a label to be specified along with a short description of the relevance of the external reference. This relationship is a multi-link relationship so the same referenceable can link to the same external reference entity multiple times, typically with different labels.

ExternalStandard entity

ExternalStandard is a special type of external reference that refers to a published standard. If a component created from this standard is catalogued, it is linked to the ExternalStandard using the ExternalReferenceLink relationship.

ExternalSourceCode entity

ExternalSourceCode is a special type of external reference that refers to software source code source. If the component created from this source code is catalogued, it is linked to the ExternalSourceCode using the ExternalReferenceLink relationship.

ExternalDataSource entity

ExternalDataSource is a special type of external reference that refers to an external data source. It is possible that the data from this data source has been extracted and is available internally. The internal version is typically catalogued as a DigitalProduct or a simple Asset. These elements are then linked to the ExternalDataSource using the ExternalReferenceLink relationship.

ExternalModelSource entity

ExternalModelSource is a special type of external reference that refers to an external model (analytical, AI, ...) source. It is possible that the code for this model has been extracted and is available internally. The internal version is typically catalogued as a DigitalProduct or a simple Asset. These elements are then linked to the ExternalModelSource using the ExternalReferenceLink relationship.
