Eclipse EMF

• Java framework for

b ildi (E li )

XML Schema UML Java Ecore XMI

building (Eclipse) applications based on models

• Many tools can operate
• n EMF metamodels and

models: ATL oAW models: ATL, oAW, Epsilon, EMFT

• Tool infrastructure for

M d l D i E i i Model-Driven Engineering

• Similar to the Meta Object

Facility (MOF) y ( )

• Open source

Motivation

MetaEdit-EMF-Bridge

• Combines the advantages of both tool spaces
• MetaEdit is suitable for DSM

MetaEdit is suitable for DSM

• Eclipse EMF is suitable for model processing
• MetaEdit models can be processed by EMF tools and

p y vice versa

• Tool chains and re-use of (meta)models, model
