An identity is a set of assertions concerning a particular subject
identifier.

Well sure, that's pretty obvious though isn't it? dmd0 included a simple
information model along those lines. Is Dave saying this should be
pulled up to a higher level? I think that DIX could work within the
context of many alternative information models... In dmd0 we move
properties that have a name and a value. That's it. Simple to map
onto the X500 or relational models or whatever.

The above sort of exchange is a good one, among specialists in the identity and x.500 kind of world.

Unfortunately, it is not so useful for the larger community that is expected to implement or *use* these services.

Yet those are the folk who will adopt or not adopt the output of the working group.

If the working group's planned output cannot be described in a way that such folk will a) understand, and b) see immediate need for, then the dix working group will be another marginalized standards effort.

I think this underscores the disconnect that concerns me.

The task of bringing work into the IETF entails the obligation of recruiting the IETF community (and the rest of the Internet community) to understand and embrace the prior work. What it does NOT entail is telling the IETF (and larger) world that they should go and become familiar with the prior work, especially when the implication is that they are excluded from the dialogue until they do that outside (and unbounded) homework.

(For reference, my own recent experiences with DKIM's efforts to come into the IETF have reminded me quite starkly of the difference between these perspectives.)
