Hi,

I definitely think IETF should place RDF representations at those
locations, as Henry suggests (e.g. 303 to say
<http://www.iana.org/assignments/relation.rdf>). Is there really no
way we could make this happen? Since the
<http://www.iana.org/assignments/relation/*> URI:s are used directly
in many places it would be very beneficial to have those be the direct
property identifiers. (And since there is really no technology other
than RDF to precisely document their meaning as relations, not going
that direct route would necessitate cumbersome indirection.)

If not, a W3C-sanctioned vocabulary mapping each relation defined at
[1] would really be the second best. We already have [2] defining a
subset of these.

A coordinated community effort could also do of course, as long as it
was stable, durable and gained consensual support.

While I have seen definitions of these relations made by the community
before (e.g. used directly in AtomOwl, and a complete listing made by
Ed Summers, which I unfortunately cannot find now), I think we may
need something more centrally defined for these relations, as close to
official IANA status as possible. Something from the W3C could be
close enough. Boiling down to discoverability, consensus and
stability.

Best regards,
Niklas
