Ok!

   We put the decission of creating the module with the types on hold. Looking forward for more feedback on the issue.

2. L3NM
    Revision of the three main issues:
Implementation Report by Cisco. It has two main issues (https://github.com/IETF-OPSAWG-WG/l3nm/issues/110)
- Common module to have all the L3NM specific requirements. Type-like module.
[Anton]: It makes implementation simpler. Does not generate unnecessary dependencies
[Adrian]: It depends on if we need module for specific types, to avoid unnecessary imports. Also don't you only need to import types, not the entire module?
[Qin]: With L3SM we did not take an augmentation approach. If there are common types defined in both models, then we may need to find the common components. We should decouple of L3SM.
[Sriram]: Prefer to have a separate type-file for the specific parameters.
[Oscar]: Define a common type-file for the service models.
[Qin]: Is it possible to manage it as an independent draft?

[Oscar in github issues]: After the discussions, it seems reasonable to have a separate Yang module to contain the types. The suggestion is to write the module to cover the four service models (client service models, l3sm, l2sm and Network service models, l2nm, l3nm). It seems reasonable to include this module in l3nm draft instead of creating a new one to avoid dependencies.
Samier, Dan and Anton to collaborate for a first version of the split

As chair, I want to call this out since it sounds like the authors made a decision here, and I want to make sure the whole WG has a chance to weigh in.  In reading these minutes and issue #110, I can see the value of a types module to avoid what may be confusing imports, but I want to know if anyone on the WG has a different opinion.

Joe
