EnCore Enfin Experiment Model
Use cases • Target user group: Bioinformaticians, programmatic access • Simple • Set of “interesting” Affymetrix ids, • Get the relevant UniProt accession numbers • Get the surrounding interaction networks from IntAct • A bit more • Set of differentially expressed proteins in Pride • Find experiments with “similar” set of regulated genes • Get Reactome pathways • Expand protein set by IntAct, then get Reactome pathways • Even more: EnVision

enXml – the EnCORE data exchange format XML schema standard interface to services simple and easy to understand structure generic to allow various data types stores service results and keeps an audit trail minimal restrictions for data representation high degree of freedom modelling user data need for modelling guidelines to ensure service interoperability ENFIN XML

- doService ENFIN XML performs service with standard parameters - doServiceAdv performs service with custom parameters ENFIN XML - doServiceTest only echoes the input Synchronous communication service client call service
protein domain prediction tool http://www.ibi.vu.nl/programs/domainationwww/ analysis tool, not only data retrieval service possible long run times sync communication inadequate initiator for async communication model Domaination
client service ENFIN XML submit - doServiceAsync submits service with standard parameters & returns job ticket - getStatus loop reports the status of the job with specified ticket ENFIN XML if status OK retrieve - retrieveResult returns the result of job with specified ticket Asynchronous web services ticket number ticket number status ticket number
Primarily designed as framework for bioinformaticians Write your own client to access one or multiple services (example clients available in different programming languages) Very flexible access, can be tailored to your specific needs Full control over the client and its functionality Create your own services to extend the functionality of EnCORE Semi-automatic WSDL wrapper generation for services Workflow control with Taverna (Prototype) EnCore use
EnVision • EnVision: Application of EnCore in a semi-fixed data flow • Easier to demonstrate functionality than by showing a bunch of WSDLs • Production application for the analysis of (proteomics) datasets • Source for biologist feedback • EnVision(1): Technically oriented demonstrator, access to XML configuration files, XSLT output generation • EnVision2: “Friendly” end user application • Beta version • http://www.ebi.ac.uk/enfin-srv/envision2/
Protein Identifier Space Translation • PICR translates between ca. 20 protein identifier spaces • Based on sequence identity • Shows all known sequence-identifier associations, both historic and current • Based on UniParc archive of 18 million public protein sequences • Interactive use and computational access (web service, REST) • Côté RG, et al.: The Protein Identifier Cross-Referencing (PICR) service: reconciling protein identifiers across multiple source databases.
