Presentation Transcript

  1. Future Work • Formal specification of modeling language semantic is key issue • Reliance on well-established formal models of computation (i.e. finite state machines, data flow, discrete event systems) • Such an approach: Semantic Anchoring • Usage of canonical, executable models of computation (MoC) • Usage of graph transformation algorithms for mapping

  2. Metamodel Composition Matthew Emerson and Janos Sztipanovits Presented by: Zoltán Molnár

  3. State of the art • Metamodeling more of an art than science • Built from scratch • No public collection of reusable metamodels • Few best-practices for metamodeling (not understood or documented) • Benefits of metamodel libraries: • Avoidance of duplication • Emergence of high quality metamodel fragments • Recognition of key patterns and best-practices • Reduction in time-to-market for new DSMLs

  4. Metamodel Merge • MOF: Package Merge • Recursive unioning of model elements • No relation with the originating packages • MetaGME: Class Equivalence and Inheritance • Implementation and interface inheritance

  5. Metamodel Interfacing • Conceptually different but related domains • Explore interactions between two domains • Delineation of an interface • consists of new modeling elements • relations

  6. Class Refinement • A concept captured by: • DSMLA in detail • DSMLB as black-box • Relation between the constructs is hierarchical +

  7. Template Instantiation • Intended for reuse of common patterns • Common patterns recorded as abstract templates • Instantiate (replicate & concretize) • Templates: • Composition hierarchies • Modular interconnections • StateCharts-style • Data Flow graphs • Proxy metamodeling pattern

  8. New relations Composition with merge (inheritance) New elements

  9. Template Instantiation Tool • User initiates a template inclusion • Selected abstract metamodel fragment looked up • Existing objects in the metamodel are selected for roles in the chosen template (some roles might be left unbound) • Metamodel updated with the template • New relations established • New objects created for unbound roles

  10. Composition with template applied twice New relations New elements

  11. Vision • Unified Tool • Template Instantiation integrated with MIC toolset • GReAT • Benefits of composition • Semantics • Semantic mappings • Property preserving model transformations
