Hi Niklas,

Thank you for your public feedback on the RDFa 1.1 documents. This is an
official response from the RDF Web Apps WG to your issue before we enter
the 3rd Last Call for the RDFa 1.1 work this coming Tuesday. The Last
Call will last for 3 weeks, so there is still time for you to discuss
your concerns if we have not fully addressed them.

Your issue was tracked here:

ISSUE-90: CURIEorURI Value Space Collisions
https://www.w3.org/2010/02/rdfa/track/issues/90

Explanation of Issue
--------------------

Previously, we had sent you an official response from the RDF Web Apps
WG on the issue of limiting the CURIE syntax to something that wouldn't
match strings that start with "http://":

http://lists.w3.org/Archives/Public/public-rdfa-wg/2011May/0097.html

We have since revisited the issue because of an issue submitted by the
RDF WG:

https://www.w3.org/2010/02/rdfa/track/issues/125

The full discussion can be seen here:

http://www.w3.org/2010/02/rdfa/meetings/2012-01-26#Updating_the_CURIE_Syntax

Working Group Decision
----------------------

RESOLVED: Make the change on the CURIE definition in RDFa Core 1.1,
according to Niklas' e-mail, allow for ':' and prevent the use of '//'
in the reference portion of a CURIE.

http://www.w3.org/2010/02/rdfa/meetings/2012-01-26#resolution_2

That is, we have expanded CURIEs to address real-world use cases, such
as Facebook using the ':' character in their CURIE references. We have
also limited CURIEs to prevent CURIE references starting with "//", thus
preventing the mistaken usage of "http://" as a CURIE.

Feedback
--------

Since this is an official Working Group response to your issue, we would
appreciate it if you responded to this e-mail and let us know if the
decision made by the group is acceptable to you as soon as possible.
