Any Object Type or Classification in the Data Model can be mapped to external schemas and be offered as output through the API. For example, it is possible to map a Data Model towards a more semantic and conceptual schema like CIDOC CRM, or simply apply metadata vocabularies like Dublin Core.

Example: Mixing Schemas

Group multiple elements by applying the same property to the name and vary in their class by supplying a specific type. See the following example for 'crm:P131_is_identified_by':

This schema is illustrative and demonstrates some of the possibilities.
