Re: [Rtg-yang-coord] Taxonomy of YANG models

[Dean Bogdanovic <[e-mail]>]

Qin,

I highly agree that classification is needed. Have few questions for you:

What you have listed is more a nomenclature then taxonomy/classification

Is your goal to achieve classification within routing area or across IETF?

For the classification, I would suggest to classify models broadly into
config
and
service models

Config models can be classified into standard and vendor proprietary models and service models can be classified into service components and service model.

Example
BGP config model

There is a common standard BGP config model and proprietary vendor model.

Service component is functional BGP config needed for a service, like Pseudowire MPLS L2VPN, which would be service model.

Once we can agree on such classification, we can discuss as next step hierarchical tree for models based on the above classification.

Dean
P.S. I'm in process of writing draft that explains to more details data model classification as above

Hi,
David and I talked about taxonomy of YANG model recently. I have applied such kind of taxonomy to the YANG models Summary table available at:
https://trac.tools.ietf.org/area/rtg/trac/wiki/RtgYangCoordSummary#
e.g., we classify models in the summary table into several topic groups:
*  Topic Groups:
o a. IP ROUTING (Core routing, ISIS, OSPF,etc)
o b. MPLS (MPLS-TE, MPLS-TP, GMPLS,LDP,etc)
o c. Traffic Engineering (RSVP-TE, ISIS-TE, OSPF-TE,PCEP, etc)
o d. Data Plane Encapsulation (NVO3, SFC,Softwire,L2TPEXT)
o e. Service (IP VPN, ETH VPN, PW Service,etc)
o f. I2RS (RIB, Topo,etc)
o g. OAM (LIME, BFD, TRILL OAM, MPLS OAM,etc)
o h. Miscellaneous (QoS, ACL, SYSLOG, SNMP,etc)
We believe the taxonomy of YANG models is important and but needs more discussion on the list. Let us know if this Topic Group classification makes sense to you or you have any other input or correction.
Regards!
