It's called RSS 1.0! RSS 1.0 limits the full RDF syntax, and > allows for RDF extension data to be included both inline or by reference. Personally I have no problem with RSS 1.0. My proposal was for those who want to push for simplification. Having a simple feed that points to full blown totally unrestrained RDF files is one solution that allows us to cover all design goals. Come to think of it, If Dave Winer would allow optional semref element in his feeds, that would solve the problem. > This fragment: > <rdfs:seeAlso> > <rdf:Description rdf:about="http://rdfweb.org/people/danbri/rdfweb/danbri-foaf.rdf"> > <dc:format>application/rdf+xml</dc:format> > </rdf:Description> > </rdfs:seeAlso> I have no problem with this. All the information is all on one node and we know exactly what parser to use should we choose to dereference the link. > I would just write: > <rdfs:seeAlso rdf:resource="http://rdfweb.org/people/danbri/rdfweb/danbri-foaf.rdf"/> > since rdfs:seeAlso is a pretty strong hint that the thing pointed to is > RDF. This is a problem for automated agents that do not want to *guess* at hints, nore can they attempt a dereference before they render their results. It was your own sccuterplan that broght this to my attention. I did as best as I could to guess which referecnes were to RDF and which were not. See the screen shot below. Note the ratio of references to RDF documents (red ~read~> buttons) to non RDFdocuments (blue ~web~> buttons). <http://robustai.net/sailor/screenshots/scuterplan.html> Look, suppose the web were designed so that when a browser rendered a hyperlink it had to *guess* whether to build a button for the human user to click on or not. Do you think that such wishy washy hyperlinks would have been as widly deployed as our blovid <a href> ? > rdfs:seeAlso is deployed and deployable already. > BTW http://www-106.ibm.com/developerworks/xml/library/x-foaf2.html and > http://www-106.ibm.com/developerworks/xml/library/x-foaf.html gives a nice > overview of how we're using this technique in FOAF to link RDF documents > together. I've done a lot of browsing around your RDF files. Congratulations, seems you have autored more RDF than anyone else that I know of. But had you depolyed a tightly defined semref instead of rdfs:seeAlso, it would have saved me and my sailor from going off on many a wild goose chase. Seth Russell http://robustai.net/sailor/
