[clue] CLUE schema definition proposal

[Simon Pietro Romano <[e-mail]>]

Dear all,

together with Roberta Presta, I have lately tried to get in synch with the current state of the art in CLUE. In the next few days, we're going to provide you with some feedback about both the framework and the data model.
In the meantime, we have started to work on a schema definition for CLUE, which has been included in a straw-man draft proposal that you can find on-line at the following URL:

http://www.ietf.org/id/draft-presta-clue-data-model-schema-00.txt

We hope this can foster discussion and prove useful for completing the on-going work. As a first, very high level comment, we think that the framework document might be somehow restructured in order to just contain the
overall description of the CLUE architecture and components, without delving into the details associated with the data structures. On the other hand, a new document might be proposed, which basically merges the already existing
data model draft from Allyn and Andy (http://tools.ietf.org/html/draft-romanow-clue-data-model-01) and the 'schema definition' draft we are working on. If this sounds reasonable to the WG, we might then also add some more information
to the current call flows documents (http://tools.ietf.org/html/draft-romanow-clue-call-flow-02 and http://tools.ietf.org/html/draft-kyzivat-clue-telemedical-callflow-01), basically showing the exact content of the CLUE messages (and transported data). For this last part, we might work on automatically generating CLUE-compliant data structures, starting from the schema definition, in much the same way as we did for both XCON and MEDIACTRL in the past.

If you think this is worth discussing, we can talk about the details during next Monday's conference call.

Cheers,

Simon and Roberta
