Hi Sandro, Thanks for picking this one up. There are a host of difficult issues to be resolved concerning the semantics of URI's. We do have an issue: http://www.w3.org/2000/03/rdf-tracking/#rdfms-resource-semantics which I'm treating as a catch all for these issues. I have added a reference to your message. There is also an editorial issue here, in that the example in M&S uses URI's which may cause confusion. As such I've added a reference to your message under: http://www.w3.org/2000/03/rdf-tracking/#rdfms-editorial Brian > rdfms-things-described-by-web-pages or something > > From: Sandro Hawke (sandro@w3.org) > Date: Fri, Aug 31 2001 > > *Next message: zhenye@yongjie-zy.com: "委拓輝斥議寮伏炎彈揮指社?" > > * Previous message: CDrom Another Side Solution: "CDrom Another Side Solution" > * Next in thread: Aaron Swartz: "HTTP resources and Resources (was: rdfms-things-described-by-web-pages or something)" > * Reply: Aaron Swartz: "HTTP resources and Resources (was: rdfms-things-described-by-web-pages or something)" > * Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] > * Other mail archives: [this mailing list] [other W3C mailing lists] > * Mail actions: [ respond to this message ] [ mail a new topic ] > > -------------------------------------------------------------------------------- > > Message-Id: <200108311536.LAA13692@tux.w3.org> > To: www-rdf-comments@w3.org > From: Sandro Hawke <sandro@w3.org> > Date: 2001年8月31日 11:36:01 -0400 > Subject: rdfms-things-described-by-web-pages or something > > I'm looking on the issues list and not finding this.
