Some additional thoughts regarding the “name”… I can understand why people are averse to an old ISO acronym like “PICS” – but there are some accurately chosen words in that acronym. Let’s examine this:
P = Protocol This is redundant – implicit given this is about IS-IS Not needed I = Implementation What is being described is the state of an implementation. Needed I don’t think any of the suggested alternatives (“support” “functionality” “feature”) are as appropriate. C = Conformance Yes – we are reporting conformance – but what else would we report? Non-conformance?? Not needed S = Statement A noun to define “what” is being produced. This is needed – but I think there are a number of synonyms which might be equally as apt: “Report” “Description” “Information” “Summary” “Record” “Declaration” My first choice: ietf-isis-implementation-description.yang, isis-id (YANG Module for IS-IS Implementation Description) My second choice: ietf-isis-implementation-declaration.yang, isis-id (YANG Module for IS-IS Implementation Declaration) Some additional notes: I have to admit I was tempted to choose “isis-implementation-statement” – which could lead to the abbreviation “is-is-is” – but I thought better of it. 😊 I also considered “isis-implementation-report” – but as “implementation-report” is already used in the IETF for a different purpose I thought it would be confusing.

We can see where the more granular definition takes us and I’ll help with the OSPFv2/OSPFv3 models. Hopefully, the enthusiasm for implementation will match our IGP protocol support modeling efforts.
