Bringing caBIG services together using Taverna

  1. 1. Bringing caBig services together using Taverna<br />Alexandra Nenadic, Stian Soiland-Reyes, Carole Goble<br />University of Manchester<br />All Hands Meeting, Oxford 2009-07-12<br />
  2. 2. What is caBIG?<br />Cancer Biomedical Informatics Grid<br />Biomedical platform by National Cancer Institute (NCI) in US<br />Linking cancer institutes and research organisations across the country<br />Improving the US cancer research communitity’s access to bioinformatics data and tools.<br />
  3. 3. caBIG services<br />~120 service providers across US<br />
  4. 4. caBIG services<br />75 data services<br />53 analytical services<br />Data types semantically described using a controlled vocabolary – Silver level compatibility<br />Services registered in an Index Service, with service metadata (caDSR)<br />Security infrastructure (GAARDS), delegation service, single sign-on<br />Thus – forming a grid - caGrid<br />
  5. 5. Taverna workbench<br />Open source workflow authoring and execution tool<br />
  6. 6. Taverna use<br />Used by eScientists in fields such as:<br />Bioinformatics<br />Chemistry and cheminformatics<br />Astronomy<br />Text mining<br />Social sciences<br />Music<br />.. and more<br />
  7. 7. Connecting services<br />Taverna is oblivious to the science, workflows are built by dragging and dropping how the data should flow between different services<br />Web Services<br />Local scripts<br />Java APIs<br />R<br />.. other customized invocation mechanisms<br />
  8. 8. caGrid technology<br />WS-Resource Framework (WSRF) grid services<br />Based on Globus Toolkit<br />Secured services: Extending Grid Security Infrastructure (GSI) to form GAARDS (Grid Authentication and Authorization with Reliable Distributed Services)<br />
  9. 9. caGrid extensions to Taverna<br />Browse and semantic search registered caBIG services<br />caBIG single sign-on support through GAARDS<br />Support for WSRF stateful web services<br />
  10. 10. Finding caBIG services from Taverna<br />
  11. 11. caBIG single sign-on<br />Sign in to chosen authentication service<br />Temporary certificate is issued<br />Credentials delegated to calls to grid services<br />
  12. 12. WSRF services<br />Most caBIG services can be invoked as normal WSDL services from Taverna<br />Taverna extension add supports for stateful WS-Resource Framework (WSRF) services<br />Passing endpoint references as part of the workflow<br />
  13. 13. Integrating Taverna and caBIG<br />Taverna workflow execution as a caGrid WSRF service<br />caTransfer – supporting large data<br />CQL building – customized data queries from within Taverna<br />University of Chicago / Argonne National Laboratory<br />
  14. 14. Use case: Lymphoma prediction workflow<br />
  15. 15. Use case: Lymphoma prediction workflow<br />
  16. 16. Taverna demonstration<br />Monday 2009-12-07 17:40<br />Thursday 2009-12-10 12:50<br />eScience North West Centre stand downstairs, booth 6<br />
