EMF Project Information



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, a set of adapter classes that enable viewing and command-based editing of the model, and a basic editor. Models can be specified using annotated Java, XML documents, or modeling tools like Rational Rose, then imported into EMF. Most important of all, EMF provides the foundation for interoperability with other EMF-based tools and applications, by exposing their models through a rich metadata that can be used to read and modify the objects.

EMF includes an EMF-based implementation of Service Data Objects (SDO). SDO is a framework that simplifies and unifies data application development in a service oriented architecture (SOA). It supports and integrates XML and incorporates J2EE patterns and best practices.

EMF optionally includes the XML Schema Definition (XSD). XSD is a reference library for use with any code that examines, creates or modifies XML Schemas (standalone or as part of other artifacts, such as XForms or WSDL documents).

Refer to the EMF Website, the SDO Website and the XSD Website for additional project information.

Status



EMF is being used in several existing commercial products. For more information on the current status of EMF, please see the Project Plan.
