The Eclipse EMF project is a modeling framework and code generation facility for building tools and other applications based on a structured data model. From a model specification described in XMI, EMF provides tools and runtime support to produce a set of Java classes for the model, along with a set of adapter classes that enable viewing and command-based editing of the model, and a basic editor.
EMF builds include XML Schema Definition (XSD), now a component of the Model Development Tools (MDT) project, and an EMF-based implementation of Service Data Objects (SDO). XSD provides a model and API for manipulating components of an XML Schema, with access to the underlying DOM representation of the schema document.
The next release of EMF is scheduled for June 25, 2014, along with the rest of the projects in the Mars Simultaneous Release.
