Ah; that makes sense. (I hadn't put 2 and 2 together previously.) > The > requirement for typing information for all nodes in OWL DL came from you, I > believe. If you think that typing information is not required for list > nodes, then why did you agitate for this requirement? Perhaps Jeremy, like me, didn't connect the two issues previously. There was some talk about doing a certain amount of RDFS-style inference of types in DL syntax processing. But we decided against that, and while this is, in some sense, new information, I don't think the question should be reopenend just for this. > > Jeremy > > > > [1] http://www.w3.org/2001/sw/RDFCore/20030123-issues/#timbl-03 > > [2] http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0586.html > > [3] http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Apr/0273.html > > peter -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
