The BIBLINK project defines a vocabulary, BIBLINK Core, which incorporates Dublin Core elements as well as BIBLINK-specific elements. Vocabularies such as BIBLINK which describe specific usage, and potentially draw elements from multiple namespaces, are referred to as Application Profiles in the DESIRE registry.
The relationship between BIBLINK Core and the Dublin Core is relatively complex. BIBLINK Core elements are one of:
Element from the BIBLINK namespace.
Element from the DC namespace.
Element from the DC namespace with BIBLINK scheme.
Element from the BIBLINK namespace which refines an element from the DC namespace.
The following diagram illustrates how this is represented within the DESIRE registry.
Not all elements and schemes are shown.
Schemes also have a registration authority.
The dotted notation indicates that a scheme is associated with an element in the BIBLINK application profile. For example, BIBLINK Core includes the Dublin Core element Format with the scheme MIME.
