Yes. Use [1] ... My motto is: acting rather than talking. So, I took [2] as a starting point - which is already in nice XHTML format - and manually added some RDFa. After an hour I ended up with [1] (though, to be fair, two Wii games with the kids and consuming some Easter eggs also took place in that hour). So, [1] is really a sort of an interim solution (though, in the distributed data world I do expect much more of such fixes) and I encourage Phil, who is an editor of [2] to use the template from [1] at the 'official' location. Happy Easter! (and back to Wii games, for now ;) Cheers, Michael [1] http://purl.org/NET/atom-link-rel [2] http://www.iana.org/assignments/link-relations/link-relations.xhtml -- Dr. Michael Hausenblas LiDRC - Linked Data Research Centre DERI - Digital Enterprise Research Institute NUIG - National University of Ireland, Galway Ireland, Europe Tel. +353 91 495730 http://linkeddata.deri.ie/ http://sw-app.org/about.html > From: Nathan <nathan@webr3.org> > Organization: webr3 > Reply-To: <nathan@webr3.org> > Date: Sat, 03 Apr 2010 00:14:16 +0100 > To: Danny Ayers <danny.ayers@gmail.com> > Cc: Linked Data community <public-lod@w3.org> > Subject: Re: Using predicates which have no ontology? > Resent-From: Linked Data community <public-lod@w3.org> > Resent-Date: Fri, 02 Apr 2010 23:14:54 +0000 > > Danny Ayers wrote: >> On 3 April 2010 00:53, Nathan <nathan@webr3.org> wrote: >>> Hi All, >>> >>> Any guidance on using predicates in linked data / rdf which do not come >>> from rdfs/owl.
