ISSUE-5

CURIEs in Predicate Attributes

State:
CLOSED
Product:
RDFa

Description:
Details discussed during telecon (http://lists.w3.org/Archives/Public/public-
rdf-in-xhtml-tf/2005Oct/0052.html). Debate continuing on the mailing list 
(http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2006Feb/0027.html).
 
Currently, about and href attributes are of type CURIE/URI, which means that 
the value of the attribute can be either a CURIE or a URI. When it is a CURIE, 
it needs to be wrapped in square brackets as follows: [cc:license], in order to 
differentiate CURIEs from URIs. 

Should rel, rev, property have the same CURIE/URI type? Or should they be CURIE 
only, since there is no precedent for them being URIs? 

The advantage of CURIE only is that we get automatic backwards compatibility 
for things like rel="next", which would be interpreted as CURIE in the default 
XML namespace of xhtml2. 

If we go with CURIE/URI, then we can always declare parser-level legacy 
conditions for things like rel="next", which would immediately be transformed 
into rel="[next]" or maybe even more directly to rel="[xhtml2:next]".
