2008/1/24, Richard Cyganiak: We couldn't find any indication in the SKOS documentation that skos:subject should be used *only* for creative works. I also asked on the SKOS list if this was okay, and the consensus seemed to be that it's a bit strange, but not illegal. Well, there is no domain

Hmmm, re-reading some of the SKOS docs I get the feeling that skos:subject is indeed appropriate only for documents: http://www.w3.org/TR/swbp-skos-core-guide/#secindexing | These properties [including skos:subject] can be used for subject | indexing of information resources on the web. Here

All, I agree with Bernard that SKOS needs a property for attaching resources to concepts. The problem with skos:subject at the moment is this: The Core Guide gives the impression that the domain of skos:subject is documents only. But there is no explicit domain declared in the vocabulary

Hi Masahide, If one ask me why? I would answer that it is become many of the wikipedia categories are classes and in such a case why not defining them as a Class, and not a category (that could be considered a class for some sense of that class)? Wikipedia category is a

Hi Richard, No. The Wikipedia category system is simply not appropriate as a class hierarchy. That's not a bug; it serves its purpose well, and the Wikipedia community likes it that way. It is essentially a tagging system, where tags themselves can be tagged. See [1] for an in-depth

All, We're in the process of moving the DBpedia HTML frontend (a.k.a. Pubby) to a new server at the OpenLink premises in Burlington, MA. This eliminates the cross-atlantic round trip that so far has been necessary to render every DBpedia page. Extra special thanks go to Kingsley for
