Re: [netmod] WGLC on draft-ietf-netmod-node-tags-06

Hi, Jurgen:
Thank for bringing this issue up.
Generally, I feel two drafts are orthogonal to each other. 
Draft-ietf-netmod-node-tags-06 focuses on YANG modelled data classification while draft-claise-netconf-metadata-for-collection-03 focuses on telemetry related server capability exposure, e.g.,
how frequent you can use YANG push mechanism to send the telemetry data, from where to collect the specific interested data, how to inform the client or collector when the server compute a new observable period, in other words, draft-claise-netconf-metadata-for-collection-03 more focuses on data collection protocol (e.g., yang push) related metadata.

In addition, draft-ietf-netmod-node-tags-06 doesn't need to depend on notification capability defined in RFC9196 since ietf-data-object-tags in draft-ietf-netmod-node-tags-06 defines data objects list under /tags:module-tags/tags:module. Therefore the client can look for these tags from the <operational>, <get-schema> also can be used since yang extension is defined for these tags in the ietf-data-object-tags.

Please correct me if I am wrong.

主题: Re: [netmod] WGLC on draft-ietf-netmod-node-tags-06

During the NETCONF meeting at IETF 113, Benoit presented an I-D titled

     Per-Node Capabilities for Optimum Operational Data Collection
            draft-claise-netconf-metadata-for-collection-03

and I asked why we need another metadata export mechanism given that node tags is been worked on in the NETMOD WG. The reaction during the meeting was to followup on the mailing list, i.e., there was no conclusive answer during the meeting.

I suggest that this document does not proceed until we know that it provides all mechanisms needed to support the use case described in the above mentioned I-D. If any functionality is lacking, the WG may want to investigate whether this can be addressed generically.

I'm not asking in order to debate this, as that is something for other venues, I'm merely asking that you state for the record what new mechanism is covered.
