Issue 4832: Explicit relationship for WorkProduct composition (spem-rtf)
Source: Adaptive (Mr. Pete Rivett, pete.rivett(at)adaptive.com)
Nature: Uncategorized Issue
Severity: 
Summary: In 7.1 (Associations): Using UML aggregation to represent WorkProduct
composition is painful in the metamodel since it requires Association,
AssociationEnd and Multiplicity objects etc. To link 2 WorkProducts will
thus take 7 objects (Association, 2 AssociationEnds, 2 Multiplicities, 2
Ranges) none of which carry any useful information. In contrast,
WorkDefinition has a direct subWork association.

Proposed resolution: introduce a new recursive association on WorkProduct
with ends subWork(0..*) and parentWork(0..*).

6. Explicit relationship for WorkProduct composition
In 7.1 (Associations): Using UML aggregation to represent WorkProduct
composition is painful in the metamodel since it requires Association,
AssociationEnd and Multiplicity objects etc. To link 2 WorkProducts
will
thus take 7 objects (Association, 2 AssociationEnds, 2 Multiplicities,
2
Ranges) none of which carry any useful information. In contrast,
WorkDefinition has a direct subWork association.

Proposed resolution: introduce a new recursive association on
WorkProduct
with ends subWork(0..*) and parentWork(0..*).
