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.
- GUIDs are written into the standard dependencies Lucene index which means GUIDs can be used to find configuration resources.
- Original GUIDs are preserved in the following operations:
- Cut-pasting content from one diagram to another
- Diagram import with replace option
- Original GUIDs are rewritten in the following operations:
- Diagram import with renaming
- Diagram copy-paste
- Related code utilities:
class ModelingUtils:
public static List<Resource> searchByGUID(ReadGraph graph, Resource indexRoot, GUID guid) throws DatabaseException
public static List<Resource> searchByGUID(ReadGraph graph, Resource indexRoot, String indexString) throws DatabaseException
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
