Thought you might like to know that I managed to get a good plug in
for the OpenGuides and the OG RDF support in this podcast with Talis I
Of course the whole thing is riveting ;) but if you just want to hear
the OG bit then it comes up at about 56m50sec. Seriously though, if
you're wondering why the OGs bother to expose RDF, and what benefits
this (and the wider web of data) can bring, then you may find the rest
of the podcast interesting. A discussion of web2.0-style APIs compared
to RDF starts around 28m40s.
