Wrapping SRS with CORBA: From textual data to distributed objects

Abstract

Motivation: Biological data come in very different shapes. Databanks are maintained and used by distinct organizations. Text is the de facto standard exchange format. The SRS system can integrate heterogeneous textual databanks but it was lacking a way to structure the extracted data. Results: This paper presents a CORBA interface to the SRS system which manages databanks in a flat file format. SRS Object Servers are CORBA wrappers for SRS. They allow client applications (visualisation tools, data mining tools, etc.) to access and query SRS servers remotely through an Object Request Broker (ORB). They provide loader objects that contain the information extracted from the databanks by SRS. Loader objects are not hard-coded but generated in a flexible way by using loader specifications which allow SRS administrators to package data coming from distinct databanks. Availability: The prototype may be available for beta-testing. Please contact the SRS group (http://srs.ebi.ac.uk).
