ST6RI-743 Update implementation for 2024-02 metamodel baseline

[seidewitz]

This PR updates the following metamodel files in org.omg.sysml/model with the abstract syntax changes approved in KerML FTF Ballot # 5 and SysML v2 FTF Ballot # 11.

org.omg.sysml/model

• UML files with flattened package structure

  • SysML.uml – Includes both SysML and KerML abstract syntax elements
  • SysML_only.uml – Includes only SysML abstract syntax elements (depends on KerML_only.uml)
  • KerML_only.uml – Includes only KerML anstract syntax elements

• UML files with full package structure (with XMI IDs used for normative XMI generation)

  • SysML_xmi.uml – Includes both SysML and KerML abstract syntax
  • SysML_only_xmi.uml – Includes only SysML abstract syntax (depends on KerML_only_xmi.uml)
  • KerML_only_xmi.uml – Includes only KerML abstract syntax

• Ecore files

  • SysML.ecore – Includes both the KerML and SysML metamodels, as used in the implementation
  • kerml.ecore – Includes just the KerML metamodel, without implementation-specific custom annotations

The metamodel URIs have been updated with the new date stamp that will be used for the Beta 2 submission to OMG:

https://www.omg.org/spec/KerML/20240201 https://www.omg.org/spec/SysML/20240201

(The URIs have also been updated in the JSON schema files in the org.omg.sysml/json-schema directory.)

There have been no structural changes to the normative abstract syntax. Other changes reflected in the updated metamodel files are:

• All associations are named (as required for MOF models), using the standard form A_end1Name_end2Name.
• Some constraint and operation OCL has been corrected.
• The spurious subpackages Interactions TBD (KerML) and x View and Viewpoint TBD have been removed.

@ivan-gomes The JSON schema files have been updated by globally replacing 20230201 with 20240201 in all URIs. Is this sufficient, since there are no structural changes to the abstract syntax from the 2024-01 release, or should they still be regenerated?
