One of the key concepts for the BlogMatrix platform is that we should be able to produce RDF output backing all pages of the site. To do this, we need to have a RDF vocabularies to describe the encoded data and of course the best way to do this is to reuse existing ones. Here's a couple:
- FOAF - persons, projects, organizations, groups, documents, images and online groups
- GEO - lat, lon, WGS84
- RDFizers - tools for converting existing data types into RDF (to be mined for information)
Idea: we really need to make the Link extension handle multiple links per post.
