Introduction

This is GRIA Workflow Plugins release version 1.1.0.

GRIA Workflow Plugins are components that extend the Taverna workbench and Freefluo workflow enactment engine. They enable GRIA job and data transfer operations to be composed into workflows using the Taverna workbench, and enable such workflows to be executed by the Freefluo workflow enactment engine.

Architecture

An overview of the workflow and GRID system architecture is provided in Figure 1. Only the GRIA Workflow Plugins (GWP in the figure) are provided in this release. These enable the Taverna/Freefluo system to securely allocate resources, execute jobs and execute data transfer operations at GRIA services.

GRIA documentation and software downloads are available from the GRIA homepage. Taverna information and user documentation can be found at the Taverna project site. Latest releases of the Freefluo workflow enactment engine can be obtained from the Freefluo project site.

The GRIA Workflow Service has been released along with this distribution. A workflow authored in Taverna (with the GRIA Workflow Plugins installed) can be deployed to a GRIA Workflow Service to make it available for remote clients to use as a single executable step within their own workflows.
