Lou:
I am not against to harmonize with draft-bryskin-netconf-automation-yang and actually both have already shared a lot of commonality on motivation and use cases but the model proposed in draft-wwx reduce its complexity and propose a more simple model design.
A quick question to chair:
Do you think we should start from complex advanced generalized model with many features which not sure can be supported, 
or from simple generic model in which the mechanism has been generalized in previous several revisions and clarify the relationship with many related standardized work such as YANG Push, Event MIB.

If clarifying the relationship with Event MIB is a concern, we could remove it since Event MIB is just one of work that motivates to bring this work up, in addition, 
hardware management model defined in RFC8348 also clarify relationship with ENTITY-MIB, do you think hardware management is something specific to MIB?

If I am wrong, please correct me.
Regards!
-Qin

Michael/Authors/WG,

Thank you for this work.  One of the questions in looking at this draft is the relationship to this draft to other individual work that has been discussed in the WG, notablyhttps://tools.ietf.org/html/draft-bryskin-netconf-automation-yang  . In looking at both drafts, I read it as that the latter provides general infrastructure for event-condition-actions (ECAs).  I'm less sure about your draft, in reading it it too seems aimed at a general infrastructure, but it also seems tailored to a specific set of ECAs that are aligned with the EVEN-MIB.

What is your/the authors intent?

If the former, perhaps it would be good for both sets of authors to (at least try to) work together to come up with with a merged document?  If the latter, does it make sense to adjust your draft to document your use case using the more general mechanisms of the other draft?

What do you think?

Please let me know if you think I'm misreading or missed something here.

Thanks,
Lou
