I don't have comprehensive data on any of these. The datatracker likely has some of this information but it would take effort to extract. > 1) How many security Yang models have been published? My sense is that that the number of Yang models from the SEC area is low in in comparison to other areas. Other areas do publish Yang modules on Sec related topics. > 2) How long does it take Yang models approved in the security area? I'm only tracking two data points -- I2NSF and RATS. https://datatracker.ietf.org/doc/draft-ietf-rats-yang-tpm-charra/ was adopted by the RATS WG in January 2020 and reviewed by the IESG at the last 03/10/2022 telechat. If you count from the first individual draft -00, then the time starts at Jul 2018 (which was even before the first RATS BOF at IETF 103). > 3) How many IETF yang models have been deployed? I can't say. For Yang module and most IETF work, there isn't a good sense of that answer in the aggregate. My experience is that specific WGs have a better sense of implementations and adoption of their technologies. Perhaps the I2NSF Yang module authors can give us a sense of adoption. > 4) Does the small deployment for IETF yang models change the value of the > model? At the risk of getting philosophical, such a hypothetical question depends on your definition of value, who are the stakeholders, and desired payoff horizon this technology. > The SEC-ADs sent this WG off to create Yang models.

This WG was not so much sent off to create Yang models as, like every WG, approved with a specific scope, in this case making Yang models for a narrow scope. > May I politely and respectfully suggest there are things about the > standardizing > Yang models that you have not asked about. > > The first stage of a yang model is joyous.

Help me understand how to read this progression as it relates to the I2NSF documents.

The community would know better than me on what future work is needed to better manage security protocols, IPSec, or otherwise with Yang modules. I don't see the I2NSF WG being the place to do that Yang work for security protocols in the general case.
