Dear Tom,

Good suggestions! As this Appendix is informational, we would like to incorporate them together with more inputs from YANG Doctors' review and IETF review. 

Thanks a lot!
Yuanlong

Yuanlong

I belatedly read appendix A and I am impressed.  A few minor thoughts.

1. I was confused by the Title

Transferring YANG Work to IEEE 1588 WG (Informational)

thinking you meant that the IEEE 1588 WG work would be Informational, like an Informational RFC.  What I am more used to is to start the Appendix with the statement 'This Appendix is Informational'
which I would have found clearer!

2. The start of A.1 is hard to write.  It is the IESG that approves publication, rather than an IETF WG, and I would assume that it has happened, in wording this, so perhaps start with
"   For the purposes of this appendix, assume that the
   IESG has approved the publication of an RFC containing a YANG module for a published IEEE 1588 standard.  "
and you could ask the RFC Editor to insert the number of the RFC as and when it is published; bit presumptuous perhaps, but think positive!

3.
OLD
YANG for subsequent 1588 revisions
NEW
a YANG module for subsequent 1588 revisions

4. A.2
I was around at the time of the MIB Module transfer and the problem was that the then current standard, RFC3978, did not acquire sufficient rights; hence the need to track down Contributors.  I had thought that
RFC5377/RFC5378 had fixed this but what you are proposing sounds like a good plan.

6 A.3
I don't think that the chosen prefix matters.  The namespace does since that is what gives names their uniqueness but different YANG modules can use different prefixes to refer to and import from the same namespace; and there are bound to be different modules using the same prefix within the module, if not now then in time; prefixes are not registered in any way.  (When someone says 'PTP' to me, I think RFC2637, not RFC8173:-)

So an IEEE YANG Module could use the same prefix as the IETF one, could use a different one; this is something of a live issue now, with NMDA modules replacing the initial ones; same or different namespace, same or different prefix?  hard to know what is best, or what will be at the time of the transfer.
