Yes there is one example I can think of ( not in a RDF sense ) I think 
the uid class in microformats hcard is intended to be used as a unique 
identifier of a hcard, it is also a url. The uid identifier is used to 
determine a  representative hCard [1].
I like to think of it more as the canonical url of a hCard. Itemid and 
uid do seem very similar in concept.
