  3. Project overview • Taverna-caBIG cooperation on several levels: • caGrid-enabling third party analytical services • Taverna Workbench enhancements for: • Semantic search of caBIG services • Invocation of caBIG services from Taverna workflows • Support for secure caBIG services (interacting with GAARDS infrastructure prior to service invocation) • This presentation addresses caGrid-enablement of third party analytical services (wrapping + achieving silver level of compatibility)

  4. Primary goals • Identify two publicly available analytical services currently accessible through Taverna • Wrap, i.e. caGrid-enable, the services: • Design the wrapper services in UML and semantically describe/annotate them using caBIG’s tooling (EA + SIW) • Wrap/implement and deploy them as standard caBIG services on caGrid (Introduce)

  5. Analytical service selection • Services have been selected in collaboration with caBIG Workflow Working Group, lead by Juli Klemm • Winners: • NCBI BLAST service hosted by EBI (European Bioinformatics Institute) • Protein and nucleotide sequence similarity search service • InterProScan service hosted by EBI • Scans a range of protein signatures in InterPro warehouse against a protein sequence

  6. Why these services? • Freely available • Highly reliable, hosted by EBI • Widely used by the scientific community • Can be combined with existing caBIG tools in biologically meaningful workflows • caBIO, GridPIR, etc.

  7. NCBI BLAST service • A popular sequence similarity search tool using local sequence alignment • Supports sequences of proteins, DNA, RNA • Searches sequences in a whole range of databases: • UNIPROT, NCBI, EMBL, etc. • SOAP web service hosted by EMBL-EBI

  8. InterProScan service • InterPro warehouse integrates various databases of protein domains and functional sites • Searches the InterPro warehouse using protein signature recognition methods, e.g. blastprodom, gene3d, hmmpfam, hmmsmart, scanregexp, profilescan.. • SOAP web service hosted by EMBL-EBI

  9. Why wrapping the services? • Original services use various data formats for inputs/outputs (although xml) • Does not conform to the caBIG compatibility rules • Output format was not even compatible with input format • The requirement for the wrapped service: • Translate the input data from caBIG-compatible xml to xml format understood by analytical services • Convert the received results back to a format understood by caBIG clients

  12. Motivational workflow http://www.myexperiment.org/workflows/230 Nested workflow that internally invokes NCBI BLAST and checks job status before fetching results Web Service that looks up protein sequences in a database. Will be replaced with the caBIG service caBIO. This Taverna workflow uses both Blast and InterProScan which can be replaced with wrapped versions of the services Shim that splits a stringinto a list of Fasta strings Nested workflow that internally invokes InterProScan and checks job status before fetching results

  13. Benefits of wrapped services • Making analytical services from other service providers available to caBIG users • Wrapped services are caBIG Silver Level compatible: • Ensures shared meaning and interoperability between these and other caBIG services • Data can be exchanged and understood between services

  14. How we wrapped the services (1) • Making the services ‘silver’ encompassed: • Modelled data in UML using Enterprise Architect (EA) • Exported model to XMI from EA • Using the SIW tool, the XMI file has been semantically annotated using caBIG’s vocabularies/ontologies • Common Data Elements (CDEs) have been generated for services inputs/outputs, reviewed by the curation team and loaded into caDSR production database • Annotated XMI loaded back to the EA to update UML

  15. How we wrapped the services (2) • From the EA, the UML model was exported to a set of xsd files • The xsd files have been imported into the Introduce tool, which was used to generate the skeleton APIs of the wrapped services • Axis 2 was used to invoke the original InterPro and NCBI BLAST services from the wrapper services • The wrapped services are asynchronous; job status and results are available as WSRF resource properties and can be subscribed to using WS-Notifications. There is also a synchronous version where polling is done from the client side.

  16. How it works • Client: using client library, calls wrapped WSRF web service • Service: convert input to original format, submit converted input to original service, return a Job Resource that references the jobID • Client: Subscribe to notifications from job resource • Job Monitor (server): For all jobs, check status using jobID, notify client on completion • Client library: Request output data • Job Resource: Convert data from original format,Return converted data to client

  20. Reused several data elements • Green classes in diagram reused from IRWG • Sequence, NucleicAcidSequence • DatabaseCrossReference • GeneGenomicIdentifieret al. • Red UML classes in diagram reused from PIR • ProteinSequence • Partial reuse of attributes in ProteinDomainLocation

  21. Example client NCBI Blast NCBIBlastClient client = new NCBIBlastClient(url); NCBIBlastInput input = new NCBIBlastInput(); ProteinSequenceRepresentation sequenceRepresentation = new ProteinSequenceRepresentation(); ProteinGenomicIdentifier proteinId = new ProteinGenomicIdentifier(); proteinId.setDataSourceName("uniprot"); proteinId.setCrossReferenceId("wap_rat"); sequenceRepresentation.setProteinId(proteinId); input.setSequenceRepresentation(sequenceRepresentation); NCBIBlastInputParameters params = new NCBIBlastInputParameters(); params.setEmail("mannen@soiland-reyes.com"); params.setQueryDatabase(new MolecularSequenceDatabase("", "uniprot")); params.setBlastProgram(BLASTProgram.BLASTP); input.setNcbiBLASTInputParameters(params); NCBIBlastClientUtils clientUtils = new NCBIBlastClientUtils(client); NCBIBlastOutput ncbiBlastOut = clientUtils.ncbiBlastSync(input, TIMEOUT_SECONDS * 1000); SequenceSimilarity[] similarities = ncbiBlastOut.getSequenceSimilarities(); for (SequenceSimilarity similarity : similarities) { for (Alignment align : similarity.getAlignments()) { SequenceFragment querySequenceFragment = align.getQuerySequenceFragment(); System.out.print("Q: " + querySequenceFragment.getSequence().getValue()); (..) id data
