1 The Interchange of (Meta)Models between MetaEdit+ and Eclipse EMF Heiko Kern ni ig Nashville, Tennessee, 10/19/2008 1

2 Agenda 1. Introduction 2. MetaEdit-EMF-Bridge EMF 3. Demonstration 4. Summarize The 8th OOPSLA Workshop on Domain-Specific Modeling 2

3 MetaEdit+ Tool for Domain-Specific Modeling Definition of DSLs and modeling Different views (diagram, table, matrix) Code generator Extensive model repository Commercial product, MetaCase The 8th OOPSLA Workshop on Domain-Specific Modeling 3

4 Eclipse EMF Java framework for building (Eclipse) applications based on models Many tools can operate on EMF metamodels and models: ATL, oaw, Epsilon, EMFT Tool infrastructure for Model-Driven Di Engineering i Similar to the Meta Object Facility y( (MOF) Open source XML Schema UML Ecore XMI Java The 8th OOPSLA Workshop on Domain-Specific Modeling 4

5 Motivation MetaEdit-EMF-Bridge Combines the advantages of both tool spaces MetaEdit is suitable for DSM Eclipse EMF is suitable for model processing MetaEdit models can be processed by EMF tools and vice versa Tool chains and re-use of (meta)models, model operations The 8th OOPSLA Workshop on Domain-Specific Modeling 5

7 Bridge Overview MetaEdit Eclipse EMF GOPRR M3-level mapping Ecore M3 conforms to determinates MetaEdit repository based on determinates conforms to EObject M2 Metamodel Metamodel M2-level transformation GOPRR generalization instance of Metamodel instance of conforms to based on M1 conforms to Model M1-level transformation Model The 8th OOPSLA Workshop on Domain-Specific Modeling 7
