18. Introduction to the Graphical Modeling Framework | © 2008 by Borland Software Corp; made available under the EPL v1.0 What is the GMF Runtime? A set of frameworks to help the development of Eclipse graphical editors:  Reusable components for graphical editors  A standardized model to describe diagram elements  Semantic and diagram models are distinct  Enables open and extensible graphical editors  Command infrastructure that bridges EMF and GEF  EMF provides a runtime infrastructure to instantiate and manipulate models (among other things)  GEF is an MVC-based framework to create graphical editors  Leverage various other technologies:  EMFT: Transactions, Validation, OCL  Apache Batik
