| There are three separate components lumped together under the rubric
| 'URC'. The first is basic functionality. This is being addressed under
| the URC Requirements document, but that functionality will necessarily
| evolve as we get deployment experience with URNs and URCs. 

The functionality of URCs themselves is very low.  They are records,
fully extensible.  A plausible set of requirements for their format
has been put forward, and that deserves consideration.

| There need to
| be mechanisms in place to enhance functionality. 

Would you give an example of how this is needed, please?

| The second is 
| transfer syntax or encoding syntax. There seems to be a bit of confusion
| between the transfer syntax problems and the basic functionality 
| questions: these are two facets of the problem which are separable and
| should be handled separately, and I believe that the work on URCs should
| specifically be laid out to handle these separately. 

Please explain where you think there is confusion.

| The third is basic
| agreements on what 'schema' should be used in URCs. This work is being
| done in other fora than the IETF but the IETF should have mechanisms to
| bring the work done in and publish it as RFCs. 

What you mean by schema here?  

| All of these threads 
| are more nebulous 

There's a lot of nebulousity in *this* thread, but I don't see where it 
attaches to proposals before the group, which it is the group's business 
to discuss.  Let's do that.

| and require more time than the URN work; it seems to
| me that all Leslie is suggesting is that we do URLs and URNs first
| to determine what additional requirements this may impose on the construction
| and deployment of URCs.

Then it is up to Leslie to suggest some way(s) in which further work
on URLs and URNs might require changes in what is now proposed.
