2016-02-01 DRAFT  Revised 2016-02-10

Introduction

These are the release notes for the first Apache release of Taverna Language. This release is an update that fixes bugs (TAVERNA-874) only one bug? and adds the Tavlang Tool, contributed by Menaka Madushanka and (sponsored by Google Summer of Code 2015).

Taverna Language is available for download from https://taverna.incubator.apache.org/download/language/

This release of Taverna Language, along with of Taverna OSGi Plugin System will support the upcoming Apache releases of the Taverna OSGi Plugin System, Taverna the Taverna Engine, Taverna Common Activities, and Taverna Command Line will result in a Taverna 3. 1.0 Command Line with functionality equivalent to an earlier alpha-release.

New Features

(1) Save workflow run provenance as a workflow run bundle

One new functionality of the Taverna Commandline Tool is the ability to
save the workflow run provenance as a workflow run bundle.

(2) 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.

Taverna OSGi is available for download from https://taverna.incubator.apache.org/download/osgi/

New Features

Addition of Tavlang Tool to Taverna Language

...

The Taverna Language command line (tavlang) tool accesses the features of the Taverna language modules. The tool has the following functions:

– Conversion
– Inspection
– Validation
– Viewing workflow statistics.

See For more information, see the Apache Taverna Tavlang Tool for more information.

Improvements/Enhancements

(1) OSGi Support

The OSGi support has been stabilized. The current OSGi version will be  0.2.1-incubating.

(2) Retained Functionality

These plugins ARE included in the 3.1.0 release:

– Beanshell scripts
– External Tool
– Interaction service
– REST service
– Spreadsheet
– XML splitters
– WSDL services
– XPath

Removed / Retired Features

(1) Activities

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

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?)

Disclaimer

Apache Taverna is an effort undergoing incubation at The Apache Software Foundation (ASF) sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
