Apache Taverna Engine 3.1.0-incubating, Apache Taverna Activities 2.1.0-incubating, Apache Taverna CommandLine 3.1.0-incubating

Revised 2016-06-30

Introduction

Apache Taverna Engine executes Taverna workflows, defined using Apache Taverna Language or Taverna 2's .t2flow format, and  provides OSGi services for monitoring and controlling the detailed execution of workflow.  

Apache Taverna Common Activities provide bindings for the Taverna Engine to invoke activities such as command line tools (local/ssh), Beanshell scripts,  REST and WSDL services, spreadsheet import and user interactions.

Apache Taverna Command-line Tool provides a shell command for executing Taverna workflows, with output of results to either a folder or a Research Object bundle including detailed provenance. In addition to the Taverna Common Activities, the Command-line  supports plugins using Taverna OSGi services.

New Features

(1) Improved WSDL support

This release adds improved WSDL support using Apache Woden. The code has two parsers (wsdl 1.1 based on WSDL4j and 2.0 based on Woden) that implement a common interface (inherited from “wsdl-generic” based on AXIS 1.4). The service execution part is based on embedded JAX-WS API, but given that this part is calling the abstract interface, there shouldn’t be a significant change.

Improvements/Enhancements

(1) TBD

Removed / Retired Features

(1) Activities

These activities were part of the alpha release (3.0.a2), but ARE NO LONGER supported.

– RShell
– Soaplab
– Biomart

They are now maintained (??) separately as part of the Taverna Plugin Bioinformatics and Taverna Extras. (What does this mean? Will they be part of a future release?)

This should be moved to a second release notes for the next release of Engine/Activities/CommandLine
