jORCA and Magallanes Sailing Together towards Integration of Web Services

It becomes increasingly important to support automated service discovering and composition due to the growing number of Web Services and data types in bioinformatics and biomedicine. jORCA is a user-friendly desktop client which is able to discover and invoke Web Services from different metadata repositories for services. This paper demonstrates the usefulness of jORCA for service composition by recreating a previously published workflow, starting with the discovery of data types, service composition (workflow generation) and refinement; to enactment, monitoring and visualization of results. The system has been exhaustively tested and documented and is freely available at http://www.bitlab-es.com/jorca.
