Ian, I've tried to represent your opinion on HTML+RDFa and CURIEs in this e-mail. Please correct anything in here that does not accurately represent your position re: CURIEs/prefixes/etc in HTML+RDFa.

I do not believe that Ian is open to that particular mechanism. Ian is asserting that the use of prefix:reference mapping (aka: CURIEs) in HTML+RDFa is too complicated for most authors and that they will get it wrong. We have attempted to mitigate Ian's various concerns by introducing three new concepts in RDFa 1.1 - allowing full URIs everywhere, RDFa Profiles and the @prefix attribute. He is fine with allowing full URIs everywhere. I'm pretty sure that he does not like the @prefix solution as a replacement for @xmlns and would claim that the "solution" misses the point. I'm also pretty sure that he is against having an indirection mechanism where strings map to other strings declared earlier in the document (the whole concept of CURIEs). > i.e. is the HTML editor looking to introduce well defined and easily > maintainable prefix/curie support in to HTML?

Ian is suggesting that any CURIE-like mechanism should be removed from the HTML+RDFa specification. The alternative solution, as I understand it, is to use full URIs everywhere, or pre-define tokens that should be used when describing particular semantic objects... basically, what Microdata does. He has also stated that he is open to other mechanisms that accomplish our goals that have yet to be discovered. > as an aside, if @prefix is defined by a specification which extends > HTML, then does it fall under the HTML editors remit to maintain @prefix? Strictly speaking, no it does not. Ian will most likely treat @prefix in the same way that he has treated the HTML+RDFa spec, as something built on top of HTML5. -- manu -- Manu Sporny (skype: msporny, twitter: manusporny) President/CEO - Digital Bazaar, Inc. blog: Saving Journalism - The PaySwarm Developer API http://digitalbazaar.com/2010/09/12/payswarm-api/
