note defines a mapping to RDF that also includes a way to map @itemref. I do not know about Niklas' tool in this respect (sorry Niklas!), but I would expect Gregg's parser:


does it and, as far as I know (sorry for the blatant self-promotion) my microdata mapper does it, too:


(Oh boy, I have just opened myself to possible bug reports:-)

Of course, the problem that all these would generate RDF directly, ie, you would have to plug the result into some RDF visualizer. But it may still help.

(But I would try Niklas' tool first to see if he does @itemref. Knowing Niklas, I would not be surprised:-)

I think it can work as a bookmarklet, so you could do it all in-browser. Niklas can say more.
