           summary="The Extended Editing Framework aims at giving another way to improve the EMF model creation phase by providing new services dedicated to editing and using more appealing editing elements. The way to obtain these services and elements is based on a generative approach similar to the EMF.Edit one. The framework provides advanced editing components for the properties of EMF elements and a default generation based on standard metamodels using these components."

           summary="In order to improve the software development industrialization, a major step consists in mass-producing software. This mass-production must be customizable, and must be able to support complex, large-scale and heterogeneous generations. Given the today's available Eclipse tools, the issue here is not to provide either a new transformation engine (model-to-model, model-to-text, text-to-model, text-to-text) or DSL (Domain-Specific Language) editor but to realize their integration for flexible software mass-production."

EMF objects can be persisted in most major relational databases and retrieved using an EMF resource approach or HQL/JPA queries. A distinctive feature of Teneo is that you can override/extend the Model-Relational mapping using JPA annotations in the model."
