Hello,
Here are my findings from the Sunday YANG sessions:
Add to RFC 69991:
adminState, operState

Add to RFC6087bis:
For referencing YANG data nodes use leafref or instance-identifier. Referencing using a simple integer or string is not recommended.
It is not recommended (or recommended?) to define value statements for  enumerations unless there is a clear use case for it.

Way of working:
When defining new models, look around for overlapping models.

Architecture:
A model should describe where it will be deployed: in a network node, in a controller, in a management server, etc.
For models deployed in a controller or management server (anywhere not on the network device) should describe, how and when the data model is/should be updated based on data from the network device.
For layered configurations (node/network/service), how do we avoid duplication?
