Abstract
This memo provides guidelines for authors and reviewers of Standards
Track specifications containing YANG data model modules. Applicable
portions may be used as a basis for reviews of other YANG data model
documents. Recommendations and procedures are defined, which are
intended to increase interoperability and usability of Network
Configuration Protocol (NETCONF) and RESTCONF protocol
implementations that utilize YANG data model modules.
