ExternalReference entity

ExternalReference entity ia a Referenceable that describes an external source of information.

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.

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.
