In combination with the Taverna Server 2.2, workflows can be submitted and executed remotely from portals and Web pages. The Server receives workflows for execution, executes it and makes the results available for collection by the portal. In this scenario, the portal acts as a client to the Server.
Web Demonstrator Interface
The Web Demonstrator represents a simple Web-based interface for accessing some of the Server’s functionalities, such as uploading and running workflows, and viewing workflow results. It uses a Ruby gem for accessing the Server’s REST interface.
The Web Demonstrator can be downloaded from the Taverna Web site as part of the Virtual Machine (VM) that has the Demonstrator and Taverna Server pre-installed. All you need to do is install the VM in some virtualization software which will the run everything for you.
