Hi, I conditionally support WG adoption of this draft, with the condition being that I think that there are technical areas of this draft that should be changed (I've mentioned these previously). My interpretation of the approach currently documented in the draft assumes that the tags are treated as a special type of configuration that don't quite adhere to normal configuration rules. In particular, the approach assumes that the server will pre-populate the running configuration with the server default tags. A client can then fetch and modify these and push them back to the server. However, I think that this approach will both bloat the configuration and violates the principal that the contents of the configuration should be owned by the client, not the server. And probably raise various other corner case conditions as well (e.g. what do you do if the server software is upgraded and the tags change? how do you merge the current client and new server defaults together?) Instead, I think that the tags should make use of the NMDA architecture and be treated entirely as regular configuration: - <operational> would always report the current set of tags in effect (system default values, overridden by any tags add/removed/modified via configuration). - <running> would only contain any configured changes to the tags (additional tags could be added, or existing tags could be marked as being changed or deleted). - No reset IPC is required, since it is just regular configuration. I think that the draft should also support NMDA by augmenting YANG library bis.
