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.
