Versionig Phase 8 - Versionierte References

Einleitung

Reference Values referenzieren immer bestimmte Versionen einer Entity (e.g. 1234@123ABC) oder die jeweils aktuellste Version (e.g. 1234@HEAD). Wenn nicht anders angegeben, ist HEAD immer der Default. Dies könnte in Zukunft für bestimmte Kontexte anders definiert werden, z.B. durch bestimmte Parents.

DoD

• Backend reference_data: Einfügen einer Column _iversion INT UNSIGNED DEFAULT NULL, FOREIGN KEY (value, _iversion) REFERENCES entity_version (entity_id, _iversion). Diese ist NULL, wenn der HEAD der Entity gemeint ist, und zeigt ansonsten auf die interne Versionsnummer.
• Server: ReferenceValue Klasse anpassen.
• Backend: insertEntityProperty parsen der String-Representation 1234@123ABC.
• Backend: registerSubdomain dummy version in entity_versioning eintragen.
• Backend: retrieveEntityProperty, zusammensetzen der String-Representation.
• Python: nicht mehr nach int casten bei reference values

Anmerkungen zur DoD

registerSubdomain musste doch nicht angepasst werden.
