Hi Sandro,

If it's about the credibility of W3C, I believe that not caring about datatypes as basic as date, time and duration is definitely not raising the profile of the organisation :--(

I always wondered why this wasn't addressed first place. Then I have read in this thread somebody saying something like "only the datatypes that were thought to be important have been incorporated in RDF and subsequently OWL". Not very insightful indeed or were there some 'technical' reason why these datatypes were excluded?

(why did I engage into that discussion :--( if only I didn't truly believe in RDF/OWL and its future)

The people on the other side of the agreement.

And since we don't know who exactly they are, it's not trivial to
renegotiate it.    I agree if we could easily ask them, they'd almost
certainly say Yes.

The way we renegotiate, without knowing who they are exactly is to
re-charter -- it doesn't really ask everybody, but it's a reasonable
effort in that direction.

If we did it without going through this hoop, we'd be risking people not
trusting W3C as much.   That might be a risk you or I are willing to
take, but it's not up to us, it's up the W3C management and/or the
Advisory Committee.   (Oddly enough, the way we ask the AC is... by
rechartering.)  But I'm happy to ask management if they're willing to
take this risk.  I totally agree with your assessment that this is a
reasonable thing to do, and I have a hard time imagining folks objecting
on other-than-procedural grounds.    Still, following procedures is, to
put it bluntly, a large part of what makes institutions function, and
the Web IMO needs W3C to function as an institution.
