Re: [CCAMP] WG last call on draft-ietf-ccamp-wson-yang-23

[Dieter Beller <[e-mail]>]

Hi Daniele, Fatai, all,

there is a general issue the WG has to address: there are several WG 
drafts defining YANG data models for WDM networks including layer0-types:

https://datatracker.ietf.org/doc/draft-ietf-ccamp-layer0-types/

https://datatracker.ietf.org/doc/draft-ietf-ccamp-wson-yang/
https://datatracker.ietf.org/doc/draft-ietf-ccamp-dwdm-if-param-yang/
https://datatracker.ietf.org/doc/draft-ietf-ccamp-optical-impairment-topology-yang/

These YANG models are overlapping in a sense that they are defining 
containers that contain similar data. An example are transponder properties.
Different names and different type definitions are used in these drafts 
for the same transponder property.

My understanding was that layer0-types provides the foundation in terms 
of type definitions and groupings, on which the YANG models in the drafts
listed above are based in order to achieve alignment and consistency 
among them. If all these drafts listed above are progressed separately, I am
afraid that it will result in a mess making the applicability of the 
YANG data models doubtful.

To sort this out, the WG should take the time and align these drafts to 
the largest possible extent which should be beneficial for the 
applicability of
the YANG models.


Thanks,
Dieter
