BizArtifact
Artifact-centric Business Process Management
...The ArtiFact system provides an advanced, light-weight approach to specifying artifact-centric BPM applications, including their interoperation with REST- or WSDL-based services. The system includes a simple, "direct" UI for specifying ArtiFact models, an XML-based representation of those models, an engine for executing business processes according to those models, and a framework that enables multiple organizations to collaborate on a shared business process.
The ArtiFact v1.0 system is the first contribution into a community by IBM of its Siena, Barcelona, and ACSI technologies.
