[edit]Topic Subject changed to: Support for instances of relationships
(was: Link as Association Instance)
[/edit]
The
UML 2.2 Superstructure (formal) Specification in discussing InstanceSpecification says (in part):
[size=14]
7.3.22 InstanceSpecification (from Kernel)[/size]
An instance specification is a model element that represents an instance in a modeled system.
DescriptionAn instance specification specifies existence of an entity in a modeled system and completely or partially describes the entity. The description may include:
• Classification of the entity by one or more classifiers of which the entity is an instance. If the only classifier specified is abstract, then the instance specification only partially describes the entity.
• The kind of instance, based on its classifier or classifiers. For example, an instance specification whose classifier is a class describes an object of that class, while an instance specification whose classifier is an association describes a link of that association.
Before I submit a Feature Request is there any way to do this in EA build 850?
What about the issue of instances of other types of relationships?
As we move more into Instance Models, EA's fragility in this area impacts us more. I could create a new topic to discuss Instances, in general, and we could provide Sparx with our view points. See also:
Action as Activity instance? for an indication of some of the issues and some possible representations of instances.
TIA,
Paolo
