EMF is a powerful framework and code generation facility for building Java applications based on simple model definitions. Designed to make modeling practical and useful to the mainstream Java programmer, EMF unifies three important technologies: Java, XML, and UML. Models can either be defined using a UML modeling tool, an XML Schema, or by specifying simple annotations on Java interfaces whereby programmers write the abstract interfaces (a small subset of what they would normally need to write), and the rest is generated automatically and merged back into their existing code. This book thoroughly describes EMF and shows how EMF-based modeling is a foundation for fine-grained interoperability and data sharing among tools and applications. The authors provide a basic overview of the most important concepts in EMF and modeling as well as clear explanations with step-by-step instructions for defining EMF models. This book shows how the Eclipse Modeling Framework (EMF) has successfully bridged the gap between modelers and Java programmers. It serves as a gentle introduction to modeling for Java programmers and at the same time as a reinforcement of the modeler's theory that plenty of Java coding can be automated, given an appropriate tool.
