So would the 'data-model' be completely abstract or still represented in an
existing language (or both, where the language serves 'as an example'?)

Right. It was also specifically made for things like this, although 'back in the
day' there weren't much ready-to-use libraries for it. I hear things are better
now but I must confess I haven't looked :)

As it was being promoted as a data modelling language for NETCONF, it made sense to use it for a NETCONF-based application.  However, it is new and the specification, RFC 6020, is over 170 pages long; perhaps that it putting people off?  If we don't use YANG for NSCP, what should be used?

If someone is actually looking into or working on this, please give a ping, even
if it isn't much formed yet
