Subject: WG Review: NETCONF Data Modeling Language (netmod)

The NETCONF Data Modeling Language (netmod) working group in the
Operations and Management Area of the IETF is undergoing rechartering.
The IESG has not made any determination yet. The following draft charter
was submitted, and is provided for informational purposes only. Please
send your comments to the IESG mailing list (iesg at ietf.org) by
2014-04-10.

NETCONF Data Modeling Language (netmod)
------------------------------------------------
Current Status: Active WG

Chairs:
  Jürgen Schönwälder <j.schoenwaelder@jacobs-university.de>
  Tom Nadeau <tnadeau@lucidvision.com>

Assigned Area Director:
  Benoit Claise <bclaise@cisco.com>

Charter:

The NETMOD working group has defined the data modeling language
YANG, which can be used to specify network management data models that
are manipulated by the NETCONF protocol. The NETMOD working group also
defined a number of core data models as basic building blocks.

The purpose of the NETMOD working group is to support the ongoing
deployment of YANG by maintaining and evolving the core YANG
specifications based on usage experience and developing data models
written in YANG that are considered core building blocks and that do not
fall into charters of other active IETF working groups (for example a
data model for stateless packet filters).

The NETMOD Working Group will produce a maintenance release of the core
YANG specification called YANG 1.1, that is a revision of RFC 6020. The
changes to RFC 6020 are restricted in the following ways:

- All compliant YANG 1.0 modules must be accepted as compliant YANG 1.1
modules.

- All known ambiguities of YANG 1.0 and all reported defects and errata
will be addressed.

- YANG 1.1 is not adding fundamentally new data modeling concepts to the
language.

- The changes of the specification will be kept to the minimum necessary
to achieve the previously stated goals.

The NETMOD Working Group will also revise the Guidelines for Authors and
Reviewers of YANG Data Models (RFC 6087) in order to fix any ambiguities
and to incorporate the lessons learned by producing YANG data models.

The NETMOD Working Group will produce a specification how YANG-defined
data trees can be represented in JSON.

The NETMOD Working Group will not serve as a review team for YANG modules
developed by other working groups. The YANG doctors, organized by the OPS
area director responsible for network management, can act as advisors for
other working groups and they provide YANG reviews for the OPS area
directors [1].

The WG will consult with the NETCONF working group to ensure that
NETMOD's decision do not conflict with work in NETCONF.

  Apr 2014 - Submit first working group draft of the stateless packet
filter
             data model

The purpose of the NETMOD working group is to support the ongoing

The NETMOD WG may also develop any additional data models written in YANG
that the WG considers core building blocks and that do not fall under the

add such milestones as it sees fit, with the advice and consent of the
responsible AD.
