Re: Response to Call for Review: HTTP Vocabulary in RDF Working Draft

Hi Phil,

Thank you for your comments on behalf of ICRA. We have had a lot of 
discussion about a more comprehensive URI class recorded in [1] and [2] 
(same thread but separated by month):

[1] <http://lists.w3.org/Archives/Public/public-wai-ert/2006Mar/0021>
[2] <http://lists.w3.org/Archives/Public/public-wai-ert/2006Apr/0015>

Since a simple URI property seemed sufficient for our current usage, we 
decided to go the easy way for now. However, as noted, we deliberately 
put this URI property in a separate namespace to facilitate an extension 
for this part of the vocabulary. It is important to see interest in such 
a refinement from outside the ERT WG as well.

You mentioned some previous work on a URI schema and I recall some 
discussions with Danbri. Do you have some pointeres to useful resources 
which we could look at and consider refining?

Thanks also for noticing the numbering issues in section 3.

Regards,
   Shadi
