Use of Derived Associations
Legacy Issue Number: 4865
Source: Model Driven Solutions ( Ed Seidewitz)
Document: UML Profile and Interchange Models for EAI
Section: 6.2.1 (Motivation)
The last paragraph of this section (beginning "Note that these derived associations...") is not entirely clear to me. I believe that the intent is the following:
Derived associations are included in the metamodel and result in corresponding generated elements in the DTD. However, derived associations can always be computed from other information in the metamodel. Therefore, a tool would not necessarily need to store derived associations internally, though it would effectively have to compute them if it generated XML for interchange.
Reword the paragraph along the lines of what I wrote above. Also, be sure, to include the appropriate constraint for every derived association to define how it can be computed.
