Re: Telecon Agenda - November 12, 2009, 1600 UTC

CC: Manu Sporny <msporny@digitalbazaar.com>, RDFa <public-rdf-in-xhtml-tf@w3.org>
Quick follow up.  With regard to Mark's proposal at [1]:

PROPOSAL

So to bring everything together, the proposal is:

 (a) RDFa should add support for URIs in attributes that currently only
     support CURIEs;

 (b) authors should be encouraged to use safe-CURIEs in those
     attributes;

 (c) but since ordinary CURIEs may still be used, we should differentiate
     by saying that anything appearing before a colon, that is not a
     mapped prefix, is a protocol.

I disagree with (b).  I don't think there is any need for this.  If the 
processing rules are handling this, then in these contexts there is no 
need to use a safe curie.  On the other hand, the TAG will have a cow if 
we permit URIs and CURIEs in the same place.  That was their principle 
objection to the CURIE spec.  How do we overcome that hurdle?
