IISOMI Work Items

Area/Topic

• UML Modeling
  • Use of OCL in IISOMI and MEF (Scott Mansfield) 
    • Importancy=H and Urgency=L
    • ONF_LSxxx_to_MEF-ITU-T_on_OCL_v03.docx
    • iisomi2018.BZ.006.02_Requirements_for_Definitions.docx
      
  • Model/Interface Compatibility (Martin Skorupski, Thorsten Heinze, Karthik Sethuraman, Italo Busi, Nigel Davis)
    • Importancy=H and Urgency=H
    • Informaiton model backward compatibility police (e.g., change on attribute)
    • I#293 (TAPI_I#282, TAPI_P#314)
      
  • Continuation of Associations Discussion (Nigel Davis)
    • Importancy=M and Urgency=M
    • Composition/strictComposite/extendComposite and Association class and multiplicity in abstraction
  • MEF MCM – ONF Core Model Alignment (Nigel Davis)
    • Importancy=HH and Urgency=H
  • Use of Stereotypes (See 2019-02-20 IISOMI Meeting notes for the decision)
    • In general we should not use stereotypes where user-defined data-types could be used 
      
    • BitLength (We will not use bitLength stereotype property anymore. Need to be deprecated. Will use a combination of multiplicity and OCL for this purpose.)
      
• UML to YANG Mapping
  • Object Reference Mapping (use of xPath “current()” function) (All)
    • Importancy=M/L and Urgency=L
  • Mapping of Abstraction / <specify> relationship of operation (Karthik Sethuraman)
    • Importancy=H and Urgency=H
  • Mapping of complex Data Types
    • Mapping to "typedef" statement
  • Use of “when” and “must” statements (Karthik Sethuraman, Scott Mansfield)
    • Importancy=H and Urgency=H
    • This is needed for TAPI 2.2
    • Related to translation of <cond>, conditional Pac, 
    • Need to bring Rob Wilton into the discussion (Scott Mansfield's action)
  • IETF MW Test Model (Martin Skorupski)
    • Importancy=L and Urgency=L
    • About alignment between the IETF and ONF models
    • I#249
      
• Tools
  • Uml2Yang Mapping Tool updates (Xing Zhao, Karthik Sethuraman, Andrea Mazzini)
    • Importancy=H and Urgency=H/M
    • Now still need manual fix
  • Yang2Uml Mapping Tool updates
    • Importancy=M and Urgency=L
  • Use of continuously updated Eclipse/Papyrus versions (Nigel Davis, Scott Mansfield)
    • From previous (old) minutes documenting earlier decisions that may no longer hold etc.
      • Moving to Photon: Importancy=H and Urgency=H
      • Karthik has been closely using the latest versions, no serious problem in that.
      • Karthik suggest we need to move to the Photon version
      • The TR-512 core model will move to Photon in v1.4.1
      • SG15 will move to Photon in the next version of the models too
  • Style template (See2019-02-20 IISOMI Meeting notes)
    • Not to have a universal stylesheet. Every papyrus project should package and auto-apply the stylesheets used by that project.
    • Most of the issues with transferring diagrams between projects could be solved by turning off auto-resizing of class boxes.
  • Tool Chains (Augie)
