Media reuse on the web

Hi Ben,Yes, I noticed the newer version, and that vocabularies are no longer mentioned in it. I whole-heartedly agree that vocabularies are an advanced topic and the primer might not be the best place to describe them, but I still think they need an entry point that's a little more accessible than what currently exists.What I'd *love* to see is something along the lines of what I mention at the end of this post - a set of "gold standard" tools (validators and parsers) that developers can use to let them know that they're on the right track without needing to grok the entire RDFa specification.I like the primer overall. I think it does a good job of showing the reason for RDFa and then gives just enough information to get a vague idea of the practice. You've no doubt come across this video tutorial which contains about the same level of information:http://www.youtube.com/watch?v=ldl0m-5zLz4But it's easy to digest... Oohh, flashing lights! ;)I don't think we should underestimate the issue of accessiblity. I see RDFa as reaching out to the "normal" world from the somewhat-airy heights of RDF. It needs to be a welcoming handshake to bring people on board.Cheers.

Hi Rob,I just noticed that your link to the RDFa Primer is to a 1-year-old draft. Have you checked out the latest version:http://www.w3.org/TR/xhtml-rdfa-primer/It should be much simpler and easier to understand.One important issue it does NOT address is the creation of new vocabularies, in part because that's a fairly advanced topic. That said, your feedback on the recent RDFa Primer would be super helpful.

Hey Rob,Hope you enjoyed the talk :)If you are worried about embedding in HTML instead of XHTML, then you can use eRDF ( http://research.talis.com/2005/erdf/wiki/Main/R... ) instead of RDFa.We turn eRDF, RDFa, and uFormats into RDF without caring about how it got there. That way we don't have to pick a winner, everyone wins as long as the semantic web grows :)Paul Tarjan(|): Chief Technical Monkey :(|)

Thanks for those resources Michael, good links.The vocabulary (or excuse me, ontology ;) that I've put together only adds a few terms so 80/20 theory holds true in our case. These added terms all revolve around describing different kinds of attribution; source, yes, but what nature of source? A copy? Derived work? Inspiration?A shame to have just missed VoCampOxford. That would have been a wonderful trip.Cheers,Rob

Rob,Fair criticism re vocabularies. In my experience it is about 80% reuse of existing vocabularies (or ontologies, if you need to impress you boss;) and only in few cases you need to invent terms on your own.Please have a look at the following URIs and let me know in case you need more: + http://semanticweb.org/wiki/Onotlogies + http://esw.w3.org/topic/VocabularyMarket + http://www.schemaweb.info/ (not actively maintained)Btw, a good way to develop vocabularies and or exchange thoughts would be a VoCamp (http://vocamp.org/wiki/Main_Page).Cheers,Michael
