OpenWFEru, an open source Ruby workflow / bpm engine just released at version 0.9.9.

Expressions ported from OpenWFEja : 'save' and 'restore'. For saving and restoring workitems to and from fields or variables.

Filters got implemented as well. As in OpenWFEja, the participant expression accepts a 'filter' attribute.

A new expression 'filter' got added, it applies a filer at entry and exit of the process segmented nested within it.

An important new concept is the 'params' field automatically populated with the attribute of the participant expression :

<participant ref="toto" task="buy food" when="now" />

The participant 'toto' will receive a workitem where the 'params' is a hash containing "task" => "buy food" and "when" => "now".

- terminate the journaling documentation
