UML → YANG Mapping Tool:
O-RAN interest and potential redevelopment support

LoreLei Rouvrais

Nigel Davis

Martin Skorupski

O-RAN Alliance is looking for tooling and may also be able to fund the work on tooling.
Created a small "Tooling Coordination Team" that produced a slide set "WG10 Tooling proposal" on that topic.

Martin presented the slide set:

  • Input from various SDOs into the O-RAN information model (written in Papyrus) which is the "single source of truth"
  • Use Gendoc to create pdf-version of the information model
  • Need to create an O-RAN YANG specification which need to be able to import also existing YANG specifications from other SDOs
  • Not clear if re-engineering of existing YANG specifications to UML is required by O-RAN; e.g., 3GPP is not using Papyrus
  • See also Project proposal for UML-To-YANG
    • Goal: Complete tool supported project lifecycle
  • O-RAN is using Papyrus 2020-06 with the latest profiles
  • O-RAN wants to harmonize terminology/semantic among their teams using UML
  • UML model validation is required
  • O-RAN will provide 4 interfaces
  • Preferred is a Linux Foundation project that works on the tools
  • IISOMI Guidelines shall be used
  • Need to estimate the effort that is required for the tooling (may need to rewrite the mapping tool from scratch because a complete restructuring is necessary)

Further discussion next week when Scott is available

Papyrus-Model2Doc feature
Scott Mansfield

May 14: 2021-05-14 IISOMI Meeting notes  

Scott Mansfield presented the Model2Doc feature from Papyrus

  • still in pre-release state
  • need to install Model2Doc tool integrated into Eclipse 2021-03 (nightly build) and Papyrus 5.1 (nightly) and Model2Doc (0.8.0 nightly)
  • requires Java version greater than 11
  • creates Word files
  • need to check if Model2Doc provides at least the functionality of Gendoc
  • Gendoc does not work with newer Papyrus versions (see below)
  • Further investigation is required
  • Work continues to create a model2doc template that produces the same material as the gendoc template (class/attribute/datatype/stereotype etc.)

GenDoc no longer work with Eclipse Papyrus 2020-06.
