THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Release date: 2016-06-31
The Apache Taverna (incubating) team is pleased to announce the release of:
- apache-taverna-commandline 3.1.0-incubating
- apache-taverna-engine 3.1.0-incubating
- apache-taverna-commonactivities 2.1.0-incubating
This is the first major release of Apache Taverna since joining the incubator, following two library releases which this relies on.
Taverna Command-line
Apache Taverna Command-line Tool 3.1.0-incubating enables you to run Taverna workflows from a command prompt or shell script. Workflow results can be saved either to a folder or a Research Object bundle including detailed provenance.
The Command-line Tool can run workflows defined with Apache Taverna Language in SCUFL2 format (.wfbundle). It can also execute many Taverna 2 workflows (.t2flow) , depending on which activities they require.
Support for executing Common Workflow Language workflows and invoking Docker services is under development. Please contact the dev@taverna mailing list for details.

Taverna Engine
Taverna Command-line Tool is based on the below Taverna libraries, which developers can also use separately:
Apache Taverna Engine 3.1.0-incubating 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.

Taverna Common Activities
Apache Taverna Common Activities 2.1.0-incubating 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.

Other Taverna
In addition to the above, Taverna Command-line relies on these libraries which have been released earlier:
- Apache Taverna OSGi 0.2.1-incubating is a plugin system for Java console and desktop applications using OSGi, including an online update mechanism.
- Apache Taverna Language 0.15.1-incubating is a Java API that gives programmatic access to inspecting, modifying and converting SCUFL2 workflow definitions and Research Object Bundles.
Changes
The below highlights changes since Taverna Commandline 3.0a2. Developers should note that there are significant changes in the backend since Taverna 2.5, including a new OSGi-based plugin system and support for SCUFL2 workflow definitions.
Improvements/Enhancements
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.
Source Code Name Changes
Package names have changed to be consistent under org.apache.taverna.* and source code modules has been reorganized.
Removed / Retired Features
(1) Activities
These activities are no longer supported in Apache Taverna.
– RShell
– Soaplab
– Biomart
Their source code is available separately as part of the Taverna Plugin Bioinformatics and Taverna Extras.
The command line no longer supports the -embeddedb or -startdb storage backends. Alternative file-based backends are planned for the future.
Bug Fixes
For details of bug fixes, see:
- Changelog for Taverna Engine 3.1.0
- Changelog for Taverna Common Activities 2.1.0
- Changelog for Taverna Commandline 3.1.0
Known Issues
Installation Information
Prerequisites
Java 1.8 or newer (tested with OpenJDK 1.8)
Apache Maven 3.2.5 or newer
Installation
Version 3.1.0 is the first release of the Apache Taverna 3 Command-line Tool. It is only available as source code, as we think this release is mainly useful for development and testing.
Apache Taverna is planning to include a binary distribution of the Taverna Command-line Tool with its next release. Please contact the dev@taverna mailing list for details.
See the taverna-commandline README for details on how to build the source code.
