This guide provides the information and procedures necessary for the installation, deployment, and testing of the *caGrid Taverna Workflow Service*. The Taverna service has two main components: the WSRF wrapper and the workflow engine.

The _Taverna 2.1.2 Service_ is a WSRF implementation that wraps the Taverna engine as a WS Resource and exposes the available operations such as _Create_, _Start_, _getStatus_, and _getOutput_ for user-submitted workflows.

The _Taverna 2.1.2 Execution Engine_ is what actually runs the workflows once they are submitted to the service.
