Progress Report February 21st

I'm building Grid tags for Taverna to execute Taverna workflows through portlets. Taverna portlet should support workflow features. Generally a workflow portlet should contain these three major parts: 1) Workflow building- defining components and their relations. 2) Execute the workflow- in case of scufl they user Freefluo enactor engine. 3) monitor execution flow and apply capabilities like resume, checkpoint, cancel, remove etc. Building a workflow generation is possible by using Taverna workbench. As a result, we're focusing on enactment of the available workflows and monitor them.
