Profile URIs

In hcalendar-issues, it is ACCEPTED that each microformat should have a profile URI, like [the XFN profile].

Some issues include:

what domain to use? Candidates include:
- microformats.org
- www.w3.org
- xmdp.org
what about versioning? How to keep in sync with the wiki and test materials?
what profile URI to use for combinations, such as hcard and hcalendar?
- note HTML4.01 states "that one or more meta data profiles, [are] separated by white space"; though it's simpler for authors if they can just use one profile URI.
More profiles are needed.

One proposal is: use www.w3.org, following W3C namespace policy. As to versioning, change the profile whenever the wiki changes (within some reasonable latency, say, a couple weeks or a month). For example: an hCard Profile at w3.org, and discussion: an hCard profile that seems to work with GRDDL.

Due to inconsistent wording of the HTML specs, HTMLTidy (and other tools?) give "Warning: <head> escaping malformed URI reference" when more than one profile is used (e.g. <head profile="http://www.ietf.org/rfc/rfc2731.txt http://www.w3.org/2006/03/hcard">). However, this is valid according to the W3C HTML validator.
