• Open Options > Environment > General > Save/Load

  By default, Save UUID is unchecked. Check Save UUID Restart MagicDraw (Environment options are save only on exit)

• Open org.omg.oti.mof.schema/resources/FundamentalConcepts.mdzip

  This resource is a refactored copy of the "UML2 Metamodel with attributes", version 2.5 (See MagicDraw Help > Resource/Plugin Manager > Samples)

  Refactoring summary:

  • Move all Enumerations defined in the UML metamodel to the PrimitiveTypes library.

    In OTI MOF, datatypes (incl. Enumerations) must be defined in a library resource. In OTI MOF, the only Classifiers in a metamodel resource are metaclasses and meta associations.

  • Name all 12 associations defined in the MagicDraw UML2.5 implementation.

    Compared with OMG UML 2.5, NoMagic's MagicDraw UML2.5 metamodel has 12 extra unnamed associations.

• Exporting MD18's PrimitiveTypes library to normalized OTI MOF Json

  Invoke the DynamicScripts toolbar menu: DynamicScripts > OMG Tool Infrastructure / MOF Json > Export Libraries OTI DocumentSet configuration to OTI MOF Json Resources

  A file chooser opens prompting for a directory where to save OTI MOF normalized *.json files. Then, another file chooser opens prompting for an OTI DocumentSet configuration file. Select [resources/MagicDraw18-implementation.library.documentSetConfiguration.json]

• Exporting MD18's UML metamdel to normalized OTI MOF Json

  Invoke the DynamicScripts toolbar menu: DynamicScripts > OMG Tool Infrastructure / MOF Json > Export Metamodels OTI DocumentSet configuration to OTI MOF Json Resources

  A file chooser opens prompting for a directory where to save OTI MOF normalized *.json files. Then, another file chooser opens prompting for an OTI DocumentSet configuration file. Select [resources/MagicDraw18-implementation.metamodel.documentSetConfiguration.json]

• Unfortunately, it's pointless to do this for MagicDraw's built-in profiles (e.g. StandardProfile, SysML, ..) because these resources do not contain UUIDs. Even with Save UUIDs, the UUID of elements in built-in resources are generated fresh on every load of these resources.

• Example: [resources/examples/HybridSUV.mdzip]

  This model has been refactored from the SysML sample in <md.install>/samples/SysML/hybrid sport utility vehicle.mdzip as follows:

  • The HSUVModel package imports the ModelingDomain::Automotive Value Types package.

  • The ModelingDomain::Automotive Value Types package imports the SIDefinitions package.

  • The ModelingDomain::Automotive Value Types package applies the SysML profile.

• To export the HSUV model

  • Select the following in the browser or a diagram:

    • UML Standard Profile::StandardProfile
    • SysML
    • QUDV
    • SIDefinitions
    • ModelingDomain::Automotive Value Types
    • HSUVModel

  • From any selected package, invoke the context menu: DynamicScriptsContextMenu > OMG Tool Infrastructure / MOF Json > Export as OTI MOF Models

  • A modal dialog will prompt for a *.documentSetConfiguration.json file.

    Select [resources/examples/HybridSUV.documentSetConfiguration.json]

    This file contains OTI Characteristics for several packages/profiles identified by their OTI ToolSpecificID. Example:

        "otiCharacteristics" : {

        "overrideID" : [ ],
        "overrideUUID" : [ ],
        "excludeNestedElements" : [ ]
      }
    

    At the end, there will be a file <md.install>/dynamicScripts/ MagicDraw-PROJECT-584d20e658a78d4832cdef764e4d76.zip containing OTI MOF Json serialization for OTI MOF Profile & Model resources corresponding to the selected packages.

The OTI MOF Json relies on the UUID of every element for cross-referencing. MagicDraw 18 provides limited support for this in the following sense:

• The Save UUID environment option must be set for user-created profiles & models.

Without this option set, exporting profiles/models will produce different results on different instances of MagicDraw because MagicDraw creates fresh UUIDs in this mode.

With this option set, MagicDraw retains the UUIDs of user-defined profiles/models. However, the UUIDs of every element in a MagicDraw-provided profile/library/sample is created fresh as if Save UUID were unset because these resources do not have UUIDs.

• Except for UML and PrimitiveTypes, exporting a set of packages as OTI MOF Model resources requires including in the selection all profiles applied (directly or indirectly) and all packages imported (directly or indirectly).

This works with or without Save UUID enabled. If Save UUID is not enabled, the results will be different for different instances of MagicDraw. If Save UUID is enabled, the results will be reproducible only for user-created profiles/packages that were created with Save UUID enabled.

Note that MagicDraw's SysML and UML Standard Profile::StandardProfile do not have UUIDs: any element exported from these profiles will have freshly created UUID for every instance of MagicDraw.
