(for rendering expectations/interpretation, see VUIEquipmentInterpreter) valid for attributes and associations: Integrated like a true direct attribute seperated only for technical reasons like RGBColor which is a vector which is not a primitive base type but should be treated equally Contained a logically separated object which belongs necessarily to the core object the core object would be meaningless without these and/or the contained object would be meaningless without the core object (possibly the last two characteristic could be distinguished lateron) [to-be-deprecated?] TightlyCoupled maybe this corresponds just to tightness=Coupled/importance=Essential (but in stereotypes it's presently modelled as tightness=TightlyCoupled/importance=Associated) Coupled (if not tight/loose: tightness=Coupled/importance=Substantial) both objects are meaningful on their own, typically they have their own identity, they may be referenced from more than one object; it is meaningful to work on both objects simultaneously (i.e. in the same transaction) (but in stereotypes it's presently modelled as tightness=Coupled/importance=Associated) [to-be-deprecated?] LooselyCoupled maybe this corresponds just to tightness=Coupled/importance=Associated (but in stereotypes it's presently modelled as tightness=LooselyCoupled/importance=Associated) Reference Working on these objects is typically unrelated, i.e. in separated transactions [to-be-deprecated?] WeakReference as with Loosely/TightlyCoupled, this is maybe just like Reference with a weaker importance valid for operations: Requisite erforderlich - nicht verzichtbar Auxiliary hilfreich, unterstützend - Verwendung ist absehbar Useful nützlich, brauchbar - Verwendung ist gut möglich, vorstellbar Utilisable verwendbar - Verwendung ist grundsätzlich möglich Completing vervollständigend - alles mögliche, ohne direkten Bezug
