−	* EMF 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.
−	* The most important benefit of EMF, as with modeling in general is the boost in productivity that results from automatic code generation. [pp 23. 2.4 Generating Code Eclipse EMF.]
−	* A domain model represents that data we want to work with. The data should be modeled irrespective of the application logic.
−	* Eclipse EMF is used to model these domain models.EMF makes a distinction between Meta models and actual model. The meta model describes the structure of the model and the model with data is an instance of this meta model.
−	* In the UML world, this is equivalent to a class diagram which describes the meta-model and an object digram describes the actual model.
−	* EMF provides a pluggable framework to store the model definition, the default method is to use XMI.
−	* The Meta model can be specified in different ways - XMI, Java annotations, UML/XML schema, textual syntax called EMFatic, Graphical editors within EMF.
−	* EMF has two meta models. ECore and Genmodel.
−	* The Ecore metamodel contains the information about the defined classes. The Genmodel contains additional information for generating code, e.g. the path and file information. The genmodel contains also the control parameter how the coding should be generated.
−	* The Ecore model allows the definition of the following elements:
−	** EClass
−	** EAttribute
−	** EReference: One end of an association between two classes.
−	** EDataType: Type of an attribute.
−	* Ecore model editor shows the model itself as the root, followed by the packages, then classes and then attributes.
−
−	* UML2 modeling is an EMF-based implementation of the UML 2.x metamodel for the Eclipse platform.

−	*	+	* EGL provides a language tailored for model-to-text transformation (M2T).
		+	* EGL is a template-based code generator (i.e. EGL programs resemble the text that they generate), and provides several useful features.
		+	* A sophisticated and language-independent merging engine (for preserving hand-written sections of generated text) - To preserve user customizations of user modifications to ANT Build file. [As opposed to rolling out own merging solution using Java]
		+	* An extensible template system (for generating text to a variety of sources, such as a file on disk, a database server, or even as a response issued by a web server),
		+	* Formatting algorithms (for producing generated text that is well-formatted and hence readable) and traceability mechanisms (for linking generated text with source models). [Both distinct advantages].

 * An optional tooling definition model is used to design the palette and other periphery (menus, toolbars, etc.). (.gmftool)
 * A goal of GMF is to allow the graphical definition to be reused for several domains. This is achieved by using a separate mapping model to link the graphical and tooling definitions to the selected domain model(s). (.gmfmap)
