Basic concepts

Rationale

TODO: unique identifiers for entities like structural components, really making sure that an entity is the same as another in distributed team work

Use cases

TODO
  • Management of shared modelling concepts using export/import or shared repository
  • Full-featured inspection of old versions
  • Version comparison analysis tools

Technical details

  • A unique identifier can be attached to any resource with the L0.identifier relation:
    >-- L0.identifier <R L0.HasProperty : L0.FunctionalRelation
        L0.HasLabel "Identifier"
        --> L0.GUID
  • The version identifier is a binary GUID and its values can be handled using the utility bean class org.simantics.datatypes.literal.
  • Identifiers are only given to structural configuration components and composites in a model configuration, not diagram elements. This makes it possible to perform global comparisons between versions of a model.
  • Related code utilities:
    • class ModelingUtils:
      • public static void rewriteGUIDS(WriteGraph graph, Resource root, boolean deep) throws DatabaseException
      • public static void createMissingGUIDs(IProgressMonitor monitor, WriteGraph graph, Collection<Resource> roots) throws DatabaseException
