The need for it by DAML-S is also, in my mind, new evidence as Bijan is now working with the WSD WG on the mapping to the Semantic Web, and thus is one of the people "representing" SW/OWL in the services WGs. I agreed that adding it to DL seemed a lot of work, but adding it to Full seems like it would take very little - especially as, as Bijan pointed out in his original raising of the issue [1] - it is essentially a syntactic shortcut that doesn't change the semantics - JH At 4:18 PM -0500 7/3/03, Dan Connolly wrote: >On Thu, 2003-07-03 at 15:32, Jim Hendler wrote: >> OK, history is we received a request from Bijan Parsia to add >> daml:item to OWL.
