Ruote is a Ruby workflow engine. It’s thus a workflow definition interpreter. If you’re enterprisey, you might say business process definition.

Instances of these definitions are meant to run for a long time, so Ruote is oriented towards persistency / modifiability instead of transience / performance like a regular interpreter is. A Ruote engine may run multiple instances of workflow definitions.

Persistent mostly means that you can stop Ruote and later restart it without losing processes. Modifiability means that you can modify a workflow instance on the fly.

Process definitions are mainly describing how workitems are routed to participants. These participants may represent worklists for users or group of users, pieces of code, …
