I agree Qin;

“Produce an Information Model containing the management requirements
of a 6TiSCH node. A data model mapping for an existing protocol (such as Concise
Binary Object Representation (CBOR) over the Constrained Application …”

Would become
“Produce a Data Model expressed in Yand and enabling the management
of the 6top sublayer. A mapping for an existing protocol (such as Concise
Binary Object Representation (CBOR) over the Constrained Application …
“

Note that I reduced the scope of the data model to the 6ttop piece.

Is that what we want ?

Hi Brain, Pascal and all,

I think both what we actually did in the current 6top-interface draft, and what we are going to redo as Thomas and Xavi suggested in the last Webex, are Yang date model of 6top, instead of information model. Thus, I think we need to re-word the Charter accordingly. Make sense?

In addition, the attached file presents clear definition on both interface model and Yang model.

Thanks
Qin

I don't think the problem is in a *document*. Benoit is questioning the
wording of the proposed charter.  I would suggest reviewing his comments
in light of the current wording of the new charter text.
