MEF Forum is considering a revision (MEF 39.1) to published specification - MEF
39 Service OAM Performance Monitoring YANG Module (see Initial effort has
been on identifying errata (see attached) such as missing content and
compilation errors. However, additional effort is planned between now and April
2017 to complete project proposal to revise MEF 39. MEF is expected to review
and approve the project proposal at the April 2017 Quarterly Meeting.

Given that ITU-T SG15 developed SOAM PM tools and has ongoing work to develop
various related information/data models, MEF Forum would appreciate input from
ITU-T SG15 towards scope for project to revise MEF 39 as well as collaborating
on developing the updated PM YANG Module in support of MEF Services.

In addition, for information, MEF is also investigating required changes to
published specification - MEF 38 Service OAM Fault Management YANG Module.

MEF Forum will provide an update once the proposed work have been approved as
new MEF Projects. Additionally, to facilitate collaboration, MEF now plans to
have draft modules available in Github.

MEF meets next on April 24-27 in Frankfurt Germany.
