[foaf-dev] Fwd: [pedantic-web] Open Correspondence RDF

Great stuff re historical social networks. I'd love to see this bridged to dbpedia and the work of the linked library data group...

> dc:author doesn't exist, it's better to use dcterms:creator, and again

> letter:textReferred, but inventing letter:textReferred is OK too.

> I also think it's useful to have the body of the letter in the RDF as
