I understand that there is undoubtedly some overlap between this list and LODLAM (Linked Open Data for Libraries, Archives, and Museums), but I wanted to pass along a link to a discussion I started in the LODLAM list about the application of RDF and linked data ontologies to archival materials and authorities.
There are certainly some very knowledgeable LOD people on this list, and therefore I don't want the discussion on LODLAM to slip through the cracks. The application of linked data methodologies is tremendously important to the archival community.
