Workflows hosted in portals

The WHIP (Workflows Hosted In Portals) project is building a set of software plug-ins to enable interactive, user driven,workflow integration, sharing, and collaboration within Web portals. This software architecture enables the dynamic publishing ofworkflows, facilitating information exchange and scientific collaboration. The WHIP plug-in provides functionality to perform composition, editing and community publication of workflow descriptions and their associated semantics. In this paper we describe the WHIParchitecture and provide an example use case through pairing the Triana workflow environment with the GridSphere portal using WHIP’s client- and server-side APIs.
