Its real easy to be confused at first, but its ultimately simple enough. I liked this UMBC equity video tutorial [this video] on RDFa, its starts by explaining RDF, gives you a nice human readable notation for reference (N3) and then shows you how to put RDF into normal web pages using the RDFa attributes. I've also started publishing my own RDFa [LINK] about music events and found the RDFa distiller [LINK] handy for translating my RDFa into alternative syntaxes (there are lots) so that I can check my work. If RDFa suits your use-case, then check out the RDFa.info wiki for a review of common errors [LINK] . Even MySpace got some of these wrong. It should be noted that RDFa is not the only way to

This is all pretty confusing and I am not sure what these vocabularies mean or what is best to use for the data I am describing. Is there some trick I am missing?
