  dcterms:description """MODULE: IDENT
Identifier module of the EU DPP core ontology proposal of the CIRPASS-2 European project.

The Identifier module proposes an universal approach for identifiers used in the EU DPP CO delivered by the CIRPASS-2 European Project.  
The module describes identifiers used for the project through aspects and scheme references, if appropriate, granularity is added.
---

DESIGN RESTRICTION: Specific modules of the EU DPP CO need to use the Connector to establish a link to the Identifiers module. The link needs to be establsihed to a subclass of aIdentifier class, e.g., Product hasUniqueProductIdentifier ProductIdentifier.
---

DEPENDENCIES: This module may have dependencies to all  EU DPP Core Ontology (CO) modules that use different types of identifiers, including: CON, P_DPP, SOC, ACTOR, ...
