The Network Modeling (NETMOD) working group is responsible for the YANG data modeling language, which can be used to specify network management data models that are transported over such protocols as NETCONF and RESTCONF, and guidelines for developing YANG models. The NETMOD working group addresses general topics related to the use of the YANG language and YANG models, for example, the mapping of YANG modeled data into various encodings. Finally, the NETMOD working group also defines core YANG models used as basic YANG building blocks, and YANG models that do not otherwise fall under the charter of any other IETF working group. The NETMOD WG is responsible for: a) Maintaining the data modeling language YANG. This effort entails periodically updating the specification to address new requirements as they arise. b) Maintaining the guidelines for developing YANG models. This effort is primarily driven by updates made to the YANG specification. c) Maintaining a conceptual framework in which YANG models are used. This effort entails describing the generic context that in YANG exists and how certain YANG statements interact in that context. An example of this is YANG's relationship with datastores. d) Maintaining encodings for YANG modeled data. This effort entails updating encodings already defined by the NETMOD working group (XML and JSON) to accommodate changes to the YANG specification, and defining new YANG encodings that are needed, and yet do not fall under the charter of any other active IETF working group. e) Maintaining YANG models used as basic YANG building blocks. This effort entails updating existing YANG models (ietf-yang-types and ietf-inet-types) as needed, as well as defining additional core YANG data models when necessary. f) Defining and maintaining YANG models that do not fall under the charter of any other active IETF working group. The NETMOD working group consults with the NETCONF working group to ensure that new requirements are understood and can be met by the protocols (e.g., NETCONF and RESTCONF) developed within that working group. The NETMOD working group does not serve as a review team for YANG modules developed by other working groups. Instead, the YANG doctors, [1] as organized by the OPS area director responsible for network management, will act as advisors for other working groups and provide YANG reviews for the OPS area directors.
