Say, in some years, somebody comes up with a XYZML+RDFa spec, and this spec makes additions to the processing steps, a bit like RDFa 1.1 XTHML does. According to this text, from that moment on, it is o.k. to define the vocabulary in XYZML+RDFa. However, RDFa processors may not be able to use that, because they have not yet updated their implementation to the extended processing rules. > > I would propose to be more restrictive here, and simply say HTML5+RDFa and XHTML+RDFa. > AND? or OR. For now I am changing it to XHTML+RDFa (since we are 100% confident there will actually be one of those and that it will be compatible). > - That being said, the original proposal (I think it was Toby's) was to say that "Conformant processors MUST understand (X)HTML+RDFa, and MAY understand other RDF serializations formats". There is a difference here. Say that the market evolves in such a way that all RDFa processors understand Turtle. That means that a deployment that relies exclusively on Turtle would be fine, and the authors would not feel like breaking the rules. But the current text would not give this freedom... > Right. And it should not. How would we evern know that ALL implementations understand Turtle? We need to mandate one format. > Ivan > > ---- > Ivan Herman, W3C Semantic Web Activity Lead > Home: http://www.w3.org/People/Ivan/ > mobile: +31-641044153 > PGP Key: http://www.ivan-herman.net/pgpkey.html > FOAF: http://www.ivan-herman.net/foaf.rdf > > > > > >
