GMF Overview • “The Eclipse Graphical Modeling Framework (GMF) provides a generative component and runtime infrastructure for developing graphical editors based on EMF and GEF. ” • Significantly reduces cost of DSL tooling • GMF is part of Eclipse Modeling Project • GMF-generated solutions proved by: w. ecore diagram editor w. gmfgraph bootstrapping editor w UML 2 Tools project diagram editors w Borland Together DSL toolkit Introduction to the Graphical Modeling Framework | © 2008 by Borland Software Corp; made available under the EPL v 1. 0
