model merging

  • M. Famelis

about model algebra merge and diff relations and rules merging with rules

An Algebra for Models

  • MOF models, seen as directed, typed, attributed graphs
  • Model operations:
  • merging
  • differencing
  • matching
  • splitting
  • ...
  • “A manifesto for model merging”

(Brunet, Chechik, Easterbrook, Nejati, Niu, Sabetzadeh)

Merging and Differencing

  • “An algebraic framework for merging incomplete and

inconsistent views” (Sabetzadeh, Easterbrook)

  • “Difference detection and visualization in UML class

diagrams” (Girschick)

  • Matching
  • Suppose it has already been computed
  • Simple 1-to-1 relations
  • No inconsistencies or dependencies

about model algebra merge and diff relations and rules merging with rules

Flexible Matching Representation

  • More complex relations
  • 1-to-many, many-to-many relations
  • Semantic dependencies, inconsistencies
  • A way to handle them: Triple Graph Grammar rules
  • “Triple graph grammars: Concepts, extensions,

implementations, and application scenarios” (Kindler, Wagner)

about model algebra merge and diff relations and rules merging with rules

Merging with TGG Rules

  • Required inputs
  • A set of complex relations (ie the matching)
  • A set of TGG rules
  • A rule application mechanism
  • “Model Transformation with Triple Graph Grammars”

(Konigs)

  • End up with simply connected models
  • Open issues: Model matching, Rule creation and

generation, Rule application
