In particular the second sentence makes me wonder. Implementations MUST ensure that a modules tag list is consistent across any location from which the list is accessible. So if a user adds a tag through configuration that tag should also be seen when using any augmentation that exposes the modules tag list. - Wording - suggest to remove 'types': Tags may be IANA assigned or privately defined types."; - Leaf names: module: ietf-module-tags +--rw module-tags* [name] +--rw name yang:yang-identifier +--rw tag* string +--rw masked-tag* string Name seems to refer to a module but this is not clear until you read the description. I understand that in RFC 7895 and its bis we also just use 'name' but I would find things easier to understand if we would have this: module: ietf-module-tags +--rw module-tags* [module] +--rw module yang:yang-identifier +--rw tags* string +--rw masked-tags* string Note that I also used plural for the leaf-lists. In the description, I would also say "A list of tags associated with..." instead of "A tag associated with...". - Editorial s/This user/A user - Adding and masking the same tag What happens if config adds a tag and masks the same tag? Is the masking taking priority in this case, i.e., you first all all tags and then you filter those that are masked? - Standard tags defined in description statements I do not like this. YANG has extension statements and having to parse stuff out of free text description statements seems to be a movement backwards. - System management What is 'system management' and a 'system management protocol'? - Tag format Apparently, the colon has a special meaning in a tag string and otherwise there do not seem to be any restrictions. (Which is good, I can finally put various smileys on my gear.) Should we state explicitly somewhere that a colon has a special meaning and that tag strings are structured into a sequence of 'taggies' separated by colons? Or is definition by example good enough? - Meaning of tag masks Do masks mean a complete string match or can I mask along the prefix hierarchy, i.e., 'vendor:acme:' masks everything starting with 'vendor:acme:'? - Retrieval of the final list of tags Once I have configured tags and masks, how do I obtain the resulting tag list? Do I have to calculate this locally? Or will the final list be found in the operational state datastore (i.e., the applied config /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <https://www.jacobs-university.de/>
