Re: [CCAMP] New draft: YANG model for finite state machine, recovery use case

[Robert Wilton <[e-mail]>]

Hi Nicola,

I've only given your draft a quick scan, but I think that some of your 
terminology appears to be slightly confusing to those familiar with YANG.

The draft states that it is 'extending YANG' but I don't think that it is.

YANG itself is just a data modelling language.  The YANG language is 
extensible by using the "extension" keyword, but from a quick look 
through your draft I don't think that you are making use of that.

Instead, and I apologise if I am misrepresenting your work, I think that 
the draft defines two YANG data models:

(1) the first YANG data model describes a fairly generic event mechanism.
(2) the second YANG data model, augmenting the first, describes fairly 
generic FSMs.

I'm not sure I can really judge whether these are good things to model 
in YANG, but if this work does progress, or if you present it at Prague, 
then you may want to consider tweaking the description and terminology a 
bit.

Hopefully the feedback is of use.

Kind regards,
Rob
