Open Source Unix Shell Workflow Management Software

Cress (Communication Representation Employing Systematic Specification) allows graphical description of a wide variety of services such as in data communications/telecommunications, but Cress is not limited to this. The approach allows services to be described graphically as (work)flows of activities. Cress diagrams are automatically translated into formal languages for rigorous analysis and verification, and are also automatically translated into implementation languages for deployment and validation. Cress aims to make service design as easy as possible without requiring specialist development knowledge. It simplifies service creation to drawing diagrams, clicking buttons and defining a few tool parameters. All key functions of Cress can be controlled from the Chive diagram editor. Cress is written using portable and widely used languages (Perl and Java). It can be extended by a developer for other kinds of services that can be characterised by activity flows.
