How does a RESTCONF server indicate which ietf-yang-library revision is implemented #55

Closed abierman closed 8 years ago

abierman commented 8 years ago

The ietf-yang-library contains a /modules subtree. A RESTCONF client needs to read the /modules subtree in order to find out which revision of the module is implemented.

Some mechanism is needed to tell the client which revision is implemented

Propose that a new mandatory capability URI is added indicating the module revision

mbj4668 commented 8 years ago

But the capabilities are reported in ietf-restconf-monitoring, so now the question becomes which version of ietf-restconf-monitoring does the server support? Can we say that restconf version 1 implies a certain revision of ietf-restconf-monitoring? Or would it be better to move the capabilities list to the API resource?

abierman commented 8 years ago

I will have to remove the yang-library capabilities. Maybe the capabilities should be in /restconf/capabilities instead of /restconf/data.

Otherwise RESTCONF-1 has to hard-wire the expected revision

mbj4668 commented 8 years ago

RIght, put them in the API resource under /restconf/capabilites, i,e, in the 'restconf' grouping in ietf-restconf.yang

abierman commented 8 years ago

I think this is too disruptive and leaves only /restconf-state/streams

What about just adding a leaf with the revision data

/restconf/yang-library-revision

contains a revision-date string
