Freefluo

Freefluo is a workflow orchestration tool for web services initially developed by IT Innovation but now available to all from the Freefluo Sourceforge Site. It can handle WSDL based web service invocation. It supports two XML workflow languages, one based on IBM's WSFL and another named XScufl that is under development as part of the Taverna Sourceforge project.

Freefluo is very flexible, at its core is a reusable orchestration framework that is not tied to any workflow language or execution architecture. Freefluo includes extension libraries that enable execution of workflows written in a subset of WSFL. Support exists for for discovery via standard UDDI and recording of provenance.

Freefluo is one component within the myGrid toolkit. The myGrid toolkit is composed of numerous useful software components. These components are designed to demonstrate higher level functionalities over an existing Grid infrastructure that support scientists in making use of complex distributed resources. These higher level functionalities extend through service lookup and discovery, provenance and data storage.
