Evolution to broader scope initiated.
The exff project began life as "exPRESS for free". We've decided to broaden its scope to include tools related to systems and software engineering and information architectures beyond EXPRESS and STEP. This interim release of exff is a first step in that direction.

Better EXPRESS to UML support
The exff EXPRESS-to-UML capability has been updated. These changes begin to bring e2u into alignment with the ISO 10303-25 EXPRESS-to-UML mapping. Highlights of the update include:

• support for SELECT types;
• support for defined types that are simple types;
• two options for mapping simple types to UML;
• initial use of OCL for some redeclared attributes;
• a parameters file to allow control of some aspects of the mapping.

An "Open Source for STEP" Wiki
A group of developers interested in coordinating on Open-Source developments around STEP/EXPRESS, UML-related tools, Web-related tools and IDEs has been having discussions in the background. We've created an Open Source for STEP Wiki to help focus our thoughts and record our finding. Please contribute with any requirements, tools or random thoughts.
