What is the relationship between Dublin Core Metadata and RDF and XML?
Dublin Core Metadata Element Set (IETF RFC 2413) and RDF (Resource Description Framework) (W3C Recommendation) are two distinct specifications. Neither requires the other, but their co-evolution forms a natural complement within the Web’s greater metadata architecture. Both the Dublin Core and RDF communities have a number of members in common, and have evolved side-by-side. The Dublin Core community provided much of the basic requirements that were used to design RDF. In turn, the development of RDF provided the Dublin Core community with a much more formal underlying data model that has helped it to determine best practices and universal solutions (rather than ad hoc Band-Aids) for many of the detailed problems that were encountered during the deployment process. Below is an example of how the Dublin Core vocabulary can be used to define additional semantics about the resources described within an RDF fragment:
