Sustainable IDE (SIDE) is a set of graphical tools for developers who want to build sustainable software. Sustainable software is software you can extend easily, from a functional or technological point of view. On one hand, this means that when a user has a new requirement, it's easy for any developer to add it, even if the original author is not there anymore. On another hand, if you want to change the underlying technologies, you don't need to rewrite your existing application from scratch. Sustainable Software gives you the freedom to change technology, requirements, or achitecture. This can be achieved thanks to the use of models in a model driven software development (MDSD) paradigm.
OpenSAGA is a model-centric Web application framework. It focuses on an abstract, non-technical application model that gets translated into an actual application by OpenSAGA. The model is mostly intentional and declarative instead of procedural. It describes what is there and how it's connected to other things instead of describing what to do. OpenSAGA aims to abstract the business concerns of an application away from its technical aspects. Currently, the model is edited as XML files assisted by an XML schema and an Eclipse plugin.
OCE (OpenCascade Community Edition) is a community version of the OpenCascade Technology 3D kernel, a C++ library for 3D CAD development. It includes components for 3D surface and solid BRep modeling, visualization, data exchange (STEP, IGES), and rapid application development. OCE aims to fix bugs and improve code quality and portability.
