Introduction

Model Driven Engineering (MDE) aims capturing problems in terms of concepts. Problems are mapped to solutions by means of model

• perations defined by transformations

Problem and solution are described with the help of models Model is expressed in terms of concepts and relationships among them given in metamodels

GMLD ‘13 - 2 JULY 2013, MONTPELLIER, FRANCE

Metamodel is the central core of an ecosystem containing a wide range of artifacts

Metamodel Evolution

Classification of changes:

• Do not affect the artefacts

→

No adaptation required

• Affect the artefact:

→

Automatically adapted

→

Not automatically adapted

Change Impact Visualization

GMLD ‘13 - 2 JULY 2013, MONTPELLIER, FRANCE

• TraceVis [1] is a tool able to graphically represent

traceability information between structured data

• TraceVis has been used also to visualize traceability

links between source and target models of a transformation [2]

• Our idea: Using TraceVis to graphically represent

the impact that the changes being addressed on a metamodel can have on the artefact

Recurrent Patterns

GMLD ‘13 - 2 JULY 2013, MONTPELLIER, FRANCE

Changes in the affected artefacts are not always directly proportional to the changes in the metamodel

Uniform impact on metamodel and artifact

Recurrent Patterns

Conclusion and future works

• The problem of adapting artifacts composing a

metamodeling ecosystem when metamodel changes is intrinsically difficult

• Visualize dependencies between metamodel and

artifact in term of traceability information can help the modeler to manage the complexity

• A live monitoring of the change impact reflecting on

the artifact the proposed change could be an interesting application

• The visualization can be enriched with the

categorization of the refactoring
