Hi Ed, Jon, That's a very interesting work, indeed. About your text, I have two comments: > The skos:note, skos:changeNote, skos:definition, skos:example, > skos:historyNote, skos:scopeNote, skos:editorialNote were changed from being > of type rdfs:Property to owl:ObjectProperty. That should not be true, as they can have any kind of object, including datatyped literals... > SKOS2008 includes some new vocabulary elements for mapping concepts from one > concept scheme to another: skos:exactMatch, skos:broadMatch, > skos:narrowMatch, skos:relatedMatch. There is also skos:closeMatch Cheers, Antoine > Jon Phipps and I have been invited to speak briefly about SKOS at an > NKOS/CENDI meeting on Thursday [1]. The conveners are particularly > interested in a summary of the changes to SKOS. I've take a very rough > stab [2] at this, and would be interested in any feedback you may have > on whether I've missed some big/small changes and/or mis-characterized > them. I couldn't seem to find a summary of the recent changes to SKOS; > if one exists please let me know! > > //Ed > > PS. Along the way I hacked together a little python utility called > vdiff [3] for comparing vocabulary namespaces. It's pretty simplistic > and the output is somewhat overwhelming [4], but it helped me get a > handle on the changes to SKOS at least. If I had more time, or there > was more interest it would be nice to adapt it to possibly use some > more fully baked ideas [5,6]. Although vdiff is quite different in > that it doesn't compare distinct resources, it compares vocabulary > namespaces by guessing that say > http://www.w3.org/2004/02/skos/core#Concept is the same as > http://www.w3.org/2008/05/skos#Concept. It's not clear to me how much > this situation actually happens in practice... > > [1] http://cendievents.infointl.com/kos_workshop_091108/ > [2] http://inkdroid.org/bzr/vdiff/example/skos-changes-summary.txt > [3] http://inkdroid.org/bzr/vdiff/vdiff > [4] http://inkdroid.org/bzr/vdiff/example/skos-diff.txt > [5] http://www.w3.org/DesignIssues/Diff > [6] http://vocab.org/changeset/schema > > >
