Hi Jürgen,

Thank you very much for your comments. As draft-clemm-nmrg-dist-intent-03 addressed the differences between the policy, intent and service models, we did not address the same. This draft is about intent classification but we could add definition here, thank you for your suggestion. Initially we wanted to communicate that intent may be different thing for different users in different solutions. But we said in our presentation that the next steps for v3 is: 'Work with community to derive unified intent definition that encompasses all intent types for all solutions and intent users.'

We added tables based on Laurent's comments (this was the addition from the v1) , and the goal was to include in some tabular form the text that was in the document. Laurent suggested to use the table to position the PoCs / tools, identifying what intent types / categories they address.

Maybe we can together agree the definition of intent that could be used in NMRG and we can add it to our draft. What about the following as just a starting point for discussion in the group:

Intents are objectives of the network users, expressed in the form suitable for different user types. Intents represent what the users require from a network and not how these objectives are resolved, realized, configured and assured on the network. 

Any comments are welcome, would be great to start discussion. 

Best Regards,
Olga

So how does this interact with draft-clemm-nmrg-dist-intent-03?

I personally find the big tables confusing and not very helpful to understand the concepts. But perhaps my problem is not classification of intent but looking for a good and concise definition of what is intent, what is not intent, how intent relates to prior art on
(declarative) policy languages (or is intent just a new name?)  In that direction, I find draft-clemm-nmrg-dist-intent-03 clearer and more useful.

After voting, all of those who read it agreed that the draft is very useful. You also mentioned that we need to potentially address some additional review comments. Could everyone who has any comments please share them with us. Laurent, Jerome, could you please share your comments as well? Also, please let us know what comments you think must be addressed in for v2 to be adopted, versus what comments we can address in v3, currently planned for March/April.
