Dear all,
The YANG Model Coordination Group
<http://www.ietf.org/iesg/directorate/yang-model-coordination-group.html>
has been a success, and has served its purpose.
The plan and the time commitment (each person committed to spend 1/3 of
his time) for this group were ambitious:
* Phase 1: List of the YANG models (inventory)
* Phase 2: Tooling
* Phase 3: Help with compilation
* Phase 4: Training & Education
* Phase 5: Coordination across SDOs/Opensource
* Phase 6: Model Coordination within the IETF
* Phase 7: Standardization Priorities
Let's review the achievements. Quiet impressive for a couple of
volunteers if you ask me.
Phase 1: List of the YANG models (inventory)
Extracted all YANG data models from IETF drafts and RFCs on
http://www.claise.be/
Started to work on YANG data model catalog for the industry
Phase 2: Tooling
YANG data models extraction from drafts/RFCs
YANG data models dependency visualization
YANG data model grouping extraction and compilation
Created http://www.yangvalidator.org/
pyang integration in idnits/tracker
pyang plugin for the YANG data model catalog
Along the process we filed a couple of pyang bugs
Organized the YANG track at the IETF Hackathon
etc.
Phase 3: Help with compilation
Proactively contacted the IETF draft authors, discussing their
compilation error messages
<http://www.claise.be/IETFYANGPageCompilation.html>
Kept track of the situation here
<https://trac.tools.ietf.org/area/ops/trac/wiki/YangCoordModelExtractionandCompilation>
Flagged the duplicate YANG module names, groupings, etc.
Phase 4: Training & Education
Created some training materials, presented at IETF94
NETCONF Slides
<http://datatracker.ietf.org/doc/slides-edu-network-configuration-with-netconf/>,
YANG Slides
<http://datatracker.ietf.org/doc/slides-edu-network-configuration-with-yang/>,
pyang Slides <https://datatracker.ietf.org/doc/slides-edu-pyang-tutorial/>
Phase 5: Coordination across SDOs/Opensource
Coordinated with the IEEE/MEF/BBF, amongst others
Worked on the YANG Data Model Classification,
<https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-model-classification/>
accepted as NETMOD WG document
Based on github, we're compiling the
IEEE/BBF/Opendaylight/openconfig data models
<http://www.claise.be/YANGPageMain.html>
Helped on URN for different SDOs
YANG Modeling Efforts in the Industry
<https://trac.tools.ietf.org/area/ops/trac/wiki/YANGModelingEffortsinTheIndustry>
Phase 6: Model Coordination within the IETF
We helped with the coordination, even if the YANG routing design team
contributed significantly for the routing aspects.
Phase 7: Standardization Priorities
This is maybe where we haven't had enough time to dedicate,
even if we have identified the next steps.
See YANG Data Models in the Industry: Current State of Affairs
<https://www.ietf.org/blog/2016/03/yang-data-models-in-the-industry-current-state-of-affairs/>
I probably missed some of the achievements. Sorry about that.
Let's analyze the current situation!
It's difficult, in a voluntary-based organization to dedicate so much
time on this YANG effort. On the other hand, this group efforts helped
with the heavy-lifting job to promote YANG in the industry. Thanks for
that. These days, even if it doesn't translate yet in many RFC numbers,
YANG became a mature technology, which can now rely on a bigger community.
I expect that the YANG doctors
<https://www.ietf.org/iesg/directorate/yang-doctors.html> to take over
some of the effort here, helping with the proactive review of YANG data
models. More on this later.
Regarding the tooling aspects, the IETF hackathon will continue to play
an important role: a couple of people signed up already
Thanks to Carl, Dean, and Qin as YANG Model Coordination Group members,
and to many others who helped directly or indirectly.
I will now request to close this directorate.
Regards, Benoit (OPS AD)
