The EMF (Eclipse Modeling Framework) 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.
GMF (Graphical Modeling Framework) provides a generative component and runtime infrastructure for developing graphical editors based on EMF and GEF (Graphical Editing Framework).
The CDO (Connected Data Objects) Model Repository is a distributed shared model framework for EMF models and meta models. CDO is also a model runtime environment with a focus on orthogonal aspects like model scalability, transactionality, persistence, distribution, queries and more.
CDO has a 3-tier architecture supporting EMF-based client applications, featuring a central model repository server and leveraging different types of pluggable data storage back-ends like relational databases, object databases and file systems. The default client/server communication protocol is implemented with the Net4j Signalling Platform.
In this tutorial we will learn how to create and persist an EMF model. The tutorial is based on Eclipse Galileo, but the steps should be the same for older versions. Anyway here are the steps needed if you decide to start from scratch. Download Eclipse Galileo Download Eclipse Galileo 3.5M6 from the Eclipse.org download page, extract on your file-system and run eclipse.exe. Add EMF and Teneo support Go to Help -> Install New Software...; in the text field "Work with:" select "All Avaiable Sites". In the text just after (not labeled) enter "EMF" and wait for the results; you [...]
