Sue,

I think that only (c) is "done", and even then only to the point that a proposal is offered in the appendix D.2 in the revised-datastores draft.

(b) has never been discussed.

(a) is what this recent flap has been about.  We'll see if it's a list of datastores or capabilities or something else...

Kent


-----ORIGINAL MESSAGE-----

Kent and Juergen: 

To summarize your messages: 

a) a global datastore list
b) Each datastore contains a list of modules it contains (currently done)
c) Each module contains a list of datastores it supports. 

Is this correct?  Or did I misunderstand. 

Sue

That's a better answer.  At least now I get the sense that you actually understood what I was saying.

As for your proposal, I agree with you that it would be best to have an explicit list.  I assume that this would be another proposed change to YANG Library (i.e., Section D.2 in the revised-datastores draft).  It will be tricky to enforce the use of this version of YANG Library in RESTCONF without a -bis document...

K.
