Concept

Apache Taverna

Résumé
Apache Taverna was an open source software tool for designing and executing workflows, initially created by the myGrid project under the name Taverna Workbench, then a project under the Apache incubator. Taverna allowed users to integrate many different software components, including WSDL SOAP or REST Web services, such as those provided by the National Center for Biotechnology Information, the European Bioinformatics Institute, the DNA Databank of Japan (DDBJ), SoapLab, BioMOBY and EMBOSS. The set of available services was not finite and users could import new service descriptions into the Taverna Workbench. Taverna Workbench provided a desktop authoring environment and enactment engine for scientific workflows. The Taverna workflow engine was also available separately, as a Java API, command line tool or as a server. Taverna was used by users in many domains, such as bioinformatics, cheminformatics, medicine, astronomy, social science, music, and digital preservation. Some of the services for the use in Taverna workflows could be discovered through the BioCatalogue - a public, centralised and curated registry of Life Science Web services. Taverna workflows could also be shared with other people through the myExperiment social web site for scientists. BioCatalogue and myExperiment are another two product from the myGrid consortium. Taverna was used in over 350 organizations around the world, both academic and commercial. As of 2011, there have been over 80,000 downloads of Taverna across different versions. On February 20, 2020, Apache Incubator retired the project and removed the code from its website. Taverna workflows can invoke general SOAP/WSDL or REST Web services, and more specific SADI, BioMart, BioMoby and SoapLab Web services. It can also invoke R statistical services, local Java code, external tools on local and remote machines (via ssh), do XPath and other text manipulation, import a spreadsheet and include sub-workflows.
