Indeed one of the challenges is to define "what" intent is, but we should not limit our view/understanding to the "intent" itself. IP networking is not only the IP address, same for Intent-based networking, it is not only the intent format that is of importance. Other mechanisms, and a comprehensive view/understanding is required to know how to design the right thing(s). I think where ANIMA could help NMRG is in "scoping" the problem (what intent means in an ANIMA context/network) and/or with use cases/examples of intent-driven operations/behaviors.
