I echo Tom Petch's concern. Given the level of deployment success of IETF management efforts for the last 5-10 years, I'd suggest that we need both customer "pull" as well as technical community "push" for such an effort to succeed. While there have been arguments made for the latter, I don't see enough evidence of customer (in particular, operator) involvement to feel confident that the former has been addressed. David Harrington said: "The people who believe that YANG is more expressive and better suited for this poarticular purpose include contributors to the design of SMIv2, MIB Doctors, members of the NMRG who helped develop the SMING information and data modeling language, contributors to the SMIng WG which worked on developing a proposed SMIv3 to converge the SMIv2 standard and the SPPI data modeling language standard and the NMRG SMING approach, and engineers who have multiple independent implementations of running code for Netconf data modeling." Tom Petch said: "Sounds magnificent but who are these people and where are they? I do track the YANG and NGO mailing lists and what I see there worries me. I see a significant number of questions along the lines; of what does this mean, how can this ever work, how can I do ... and the questions are all very reasonable and need answers - which they mostly get, even if they are somewhat too often along the lines of 'oh dear', or 'more work needed'. But they are the sort of questions I, for all I have done with SMI, ASN.1 and other languages, would not have thought to ask; they come from someone at the sharp end writing code for today's boxes. Yet these questions are almost all coming from just one person with a specific market place, and if he can find so many doubts and queries, how many more are there waiting to be discovered? That one person - hi, Andy! - is doing a magnificent job but for a new language to live up to its billing, we need half a dozen such people, from different parts of O&M to find the holes; and I just do not see them, at least not on the YANG and NGO mailing lists. The answers, likewise, mostly come from the same three or so people; again, I am concerned that there are not more, given the claims of yang. This causes me to doubt that we, the IETF, really has the community of interest to undertake such a challenging assignment. Tom Petch"
