Key Differences between Z.151 and jUCMNav

Mismatches

• 6: GRL Beliefs are IntentionalElements in Z.151, whereas they are not in jUCMNav (they are a type of GRLNode, and hence cannot be associated with a value in a strategy)
• 6.1.5: Concern: Z.151 targets URNmodelElement, jUCMNav targets them now but also targets IURNDiagram
• 7.4.6: DecompositionType is different. Z.151 has {AND, XOR, IOR}, and jUCMNav has {And, Or, Xor}.
• 7.5.2: EvaluationStrategy in Z.151 may be associated to many StrategiesGroup in Z.151, but to only one in jUCMNav.
• 7.6.13 Comment: Z.151 has Comment (comment boxes) attached to UCMmap and GRLspec, jUCMNav has it attached to IURNdiagram (with a different role name)
• 9: Handling of URN data model (syntax) by jUCMNav (I believe there are small differences, e.g. postconditions in Z.151, "else" in jUCMNav)

In Z.151 but not in jUCMNav

• GRLnode has a size (width/heigth) in Z.151 but not in jUCMNav (auto-computed from content)
• NodeConnection is a URNmodelElement (whereas it is not in jUCMNav)
• 7.6.1 ConcreteGRLspec: Z.151 supports visualization of XOR/IOR as means-end
• 7.6.8 Label: GRL LinkRef have movable labels in Z.151
• 8.2.1: UCMmap singletons (in the metamodel but unused)
• 8.4.2: ComponentType (in the metamodel but unused and no GUI)
• 8.6.1: Workload decomposed in Z.151 but not in jUCMNav
• 9: Syntax for previous values of variables in post-conditions

In jUCMNav but not in Z.151

• ContributionChange and ContributionContext in jUCMNav's metamodel (defined but unused)
• ScenarioStartPoint and ScenarioEndPoint
• Everything related to KPIs
• Everything related to aspects
• Everything related to failure points
• Interfaces for nodes, diagrams, containers, connections, container references

Deprecated features in jUCMNav

• GRL IntentionalElement's priority and criticality attributes
• UCM PluginBinding's transaction attribute
• UCM Stub's pointcut attribute
• UCM orientation attribute in AND/OR forks/joins

Others...

• Use of interfaces in jUCMNav's metamodel
• Use of packages in jUCMNav's metamodel
