Part of my time I’m the maintainer of egroupware’s workflow application, a part of eGroupware Groupware.

This an open source application based on Galaxia PHP workflow engine. Most of my work on this engine has been:

  • securing the engine
  • adding robustness (error codes, transactions, warnings)
  • extending the engine with sort of plugins (agents)
  • build an egroupware application on top of it

There are still a lot of work to do on it.
