TeamWork with models

Compare and Merge with EMF Compare

Models matters ...


Eclipse Modeling project

� Modeling, Meta-modeling

� Tooling, Editors and modelers


M2T / Acceleo : generate text from models


M2M : transform models to models

� UML Tools, Query/Transaction/Validation, ...


Models are used to :

� Capture and structure knowledge

� Scaffold applications

� Code generation

� Model transformation

� Analyse legacy applications

� Normalization and interroperability

Models are used to :

And many more useful things (see all the modeling projects !) �


As such, models evolves


� Compare, merge support

� SCM integration

� History analysis

Team support


Ganymede brings ...


� End User

� Metamodel agnostic diff/merge -> demo

� Platform Team API integration (CVS, SVN..) -> demo

� User guide

� Developper

� Extensible diff model export -> demo

� Match/Diff algorithms extension

� Standalone/RCP support

� Developper guide

EMF Compare 0.8.x


Why should you bother ?


As an Eclipse user

� develop using models !


As an RCP developer

� compare your own business objects

� do not depend on Eclipse IDE

� « in memory » comparison

� produce history reports


As an « development tools » developer

� incremental processing

� « mymodel » support

� XML based file comparison


As a researcher

� testbed for models/graphs comparison algorithmes


How does it work?


Principles : models everywhere


Phase 1 : matching elements


Match engine� are « a » & « b » similars ?

� produce a match model


Generic matching engine� heuristic based

� metamodel agnostic

� 4 metrics

� name

� content

� type

� relations


Phase 2 : differencing


Differencing engine� produces the diff model from the match model


Phase 3 : extending the diff model


Diff model export


Diff model export� export a model containing « diff » and « match » model : emfdiff file


Extensibility

� Graphical modelers integration (draft) -> demo

� Documentation

� The more the better !

� Project

� Graduation from incubation status

EMF Compare 1.0 for Galileo


� Developpers

� Incremental processing

� Non regression testing (ATL..)�

� Research

� Graphical Comparison (Tobias Jähnel - University of Applied Science Nuernberg) �

� Patch model (Davide Di Ruscio - Università degli Studi dell' Aquila ) �

� Selective regression testing (Leila Naslavsky – Donald Bren School of Information and Computer Science) �

� Semantic conflicts and refactoring detection (Philip Langer - Vienna University of Technology) �

It's just a first step !
