Discussion Items

  • TR-512 v1.3 publication: Kam reported on the decision from the discussion with Timon on the publication of TR-512:
    • Location of publication:
    • Descriptive status sentence:
      • Note: this Technical Recommendations has been approved by the Project TST, but has not been approved by the ONF board.  This Technical Recommendation is an update to a previously released TR specification, but it has been approved under the ONF publishing guidelines for ‘Informational’ publications that allow Project technical steering teams (TSTs) to authorize publication of Informational documents.  The designation of ‘-info’ at the end of the document ID also reflects that the project team (not the ONF board) approved this TR.
      • To be used in all TRs that are published by Projects without ONF board oversight.  It is envisioned that only existing TRs requiring update would use this publishing method, would include this sentence in the preamble, and would use a special indicator in the Document ID
    • Status Indicator in Document ID
      • To indicate status as project approved (not ONF board approved)
      • TR-512-v1.3.1-info
    • Cleanup ONF site older documents
      • Nigel and Kam will provide instructions for cleaning up the Models-Apis page on the ONF site, then ONF will implement with web team
        • Collapse older documents into a zip for each older version 
      • Have clear indication which are current and which are the older versions
    • v1.3 and v1.3.1
      • Will wait for v1.3.1 for publishing (i.e., skipping v1.3)
      • v1.3.1 will be published once released by the Project TST
  • 2018 meeting plan

 v1.4 TopicsRick/Kam
  • Discussion on the comment regarding disclaimer:
    • Agreed that all generated files (including OpenAPI file, YANG file and whatever interface protocol files) should have a disclaimer text upfront. The mapping guideline documents should thus have a guideline similar to the one in section 5.9 of oimt2017.CH.001.00_Uml-to-ProtoBuf-Mapping, i.e.


The generator shall generate at the top of each ProtoBuf file :

    • Copyright and license text
    • generator and model version information
    • A syntax statement for version 3
    • A package statement
    • Any required import statements

  1. Sorry for not be able to attend yesterday's meeting!  January 11 Thursday IM-D is OK for me. I will update the mapping guidelines as v05 before the meeting.
