Thanks Lin, 

that is valuable information. But, indeed, it would be very important to see whether the same setup could work using RDFa's @about.

As you may have seen on Jeni's G+ discussion, I have given some thought to this in terms of RDFa. Everything can be done of course but the issue we would be facing (and I do not know how microdata solves that, actually) is what 'state' would the referred entry be. What happens to language setting, to @prefix settings, types/vocabularies, etc. What I am afraid of is that the 'referred' part would generate different RDF triples depending on where it is included into, and that sounds problematic to me...

Cheers and thanks!

Ivan

We would be able to have a checkbox on the field settings form that says this field uses an itemref. A metatag with itemref would be placed in the body and would point to the field wrapper. However, I'm not sure whether this is necessary in RDFa since 'about' could be used. I haven't dug into the code yet, so I'm not sure whether an itemref in RDFa would make this easier or take the same effort.
