Questions tagged [eclipse-emf]

Use this tag for questions about the Eclipse Modeling Framework Project (EMF)

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.
