Just to clarify the current situation: - The CURIE WD[1] is, well, moribund indeed. It is not clear whether the XHTML2 WG will ever go down the full Recommendation route with it and, if yes, when. - The RDFa syntax document[2] has included a full definition of CURIE-s because it wanted to avoid a dependency on the CURIE WD and jeopardize its advancement to a Recommendation. The current plan is to have RDFa as a Rec sometimes early spring (April?) 2008. Note, however, that _if_ [1] does become a Recommendation, the goal is to be strictly compatible with [2] (they have the same editors, actually...). Jeremy, I am not sure which 'two XHTML2.0 WDs' you were referring additionally to [1] and [2]. To the best of my knowledge, [1] supersedes any other CURIE-related work in the XHTML2 WG. For the OWL WG referring to [2] seems, at the moment, to be a safe bet, although the definition of prefix must be defined separately for the OWL functional syntax (RDFa relies on the XML syntax). I hope this helps Ivan [1] http://www.w3.org/TR/curie [2] http://www.w3.org/TR/rdfa-syntax Jeremy Carroll wrote: > > Jeremy Carroll wrote: >> >> >> I have satisfied myself that my colleagues do not have objection to >> the proposed resolution, and I am happy to support it. > > Ooops - after further feedback, I am afraid I need to modify that. > > HP will abstain on this proposal, reflecting that we have some minority > concerns ... > > - there are an excess of WDs with a claimed normative defn of CURIEs > (the CURIE WD, an RDFa WD, and two XHTML 2.0 WDs) > + a copy/paste solution would make this worse > - the prefix binding issue that is not addressed with CURIEs is > non-trivial (e.g. early versus late binding). > - tension with the SPARQL not-a-CURIE construct > - at least in the CURIE WD, the empty prefix is prebound to a specific > namespace. > - if we are going to use CURIEs in XML documents (such as the XML > serialization of the functional syntax), then > + we should be asking the XML Schema WG to extend the primitive base > types of XML Schema 1.1 (Datatypes). > + it is likely that XML tools, such as XSLT, will have difficulty in > getting the prefix binding correct. > - this TAG issue > http://www.w3.org/2001/tag/issues.html#abbreviatedURIs-56 > > > In light of these concerns I personally would advocate a fairly > conservative approach, of, at this stage: > - citing the (alegedly moribund) CURIE WD, rather than using copy/paste > - identifying in which contexts we expect users to be using CURIEs, > rather than URIs. > - letting the TAG know that we are an interested party with respect to > their issue. > > A choice to use CURIEs would make it more difficult for us to advance > past last call, before the TAG have resolved this issue. > > (I don't feel that I can in good faith vote for or against any > particular resolution, without making a bigger issue of this with my > colleagues than seems appropriate - so I ask the WG to accept that HP > will abstain, without making the normally expected efforts to get > unanimity). > > Jeremy > > > > -- Ivan Herman, W3C Semantic Web Activity Lead Home: http://www.w3.org/People/Ivan/ PGP Key: http://www.ivan-herman.net/pgpkey.html FOAF: http://www.ivan-herman.net/foaf.rdf
