OpenWFE is a workflow engine. It is robust, extensible, and scalable. Access libraries for Python, Perl, and .NET make it easy to write custom interfaces or agents (automatic participants) for a workflow-enabled system.

The workflow instantiation mechanism was completely revised, making the OpenWFE process definition language even more expressive and powerful. Functions were heavily enhanced. The worklist now relies on a decoupled store/storage system with get and put strategies: one can easily supply their own storage implementation and take advantage of existing implementations like QueryGetStrategy. The participant map service was simplified and now relies more on regular expressions: the default participant map could fit a lot of organizational models.
