Versioning is one practical problem, although the example Steve Marshall
brought up with hListing would suggest that you are absolutely right: we
should create XMDP profiles for every microformat. Another valid problem
is disambiguation between semantic html and "official" microformats. If
it doesn't have a microformats.org profile URI, it isn't a microformat.
I think however, that we can get profiles into usage even without the
XMDPs, as the provide value in the wild even if the URI doesn't resolve,
in the same way that rel="tag" works or namespace references use a URI
without requiring the URI resolve.
That works for versioning and disambiguation regardless of whether or
not the URI actually resolves.
So, how about standardizing the URI for "official" microformats so that
they can be used in disambiguation and versioning? That would also let
us know where we can start working on the XMDPs.
I don't know that this is the right addressing scheme, but it seems to
me that something like this makes sense. Then we can start using profile
URIs in the wild while simultaneously building those profiles on the
Note that standardizing a URI scheme like the above would be useful even
if we don't change the policy on requiring profiles for compliant
microformats. It would make it easier to start working on the XDMPs, for
After thinking about it, I would prefer something like this:
With restricted access to the non-draft profiles.
Thoughts on how to organize official profiles?
