The Dublin Core Metadata Initiative has established the DCMI Scholarly Communications Community, which currently includes a mailing list and a wiki.
Here's an excerpt from the home page:
The DCMI Scholarly Communications Community is a forum for individuals and organisations to exchange information, knowledge and general discussion on issues relating to using Dublin Core for describing research papers, scholarly texts, data objects and other resources created and used within scholarly communications. This includes providing a forum for discussion around the Eprints Application Profile, also known as the Scholarly Works Application Profile (SWAP) and for other existing and future application profiles created to describe items of scholarly communication.
