The Apache Taverna (incubating) project are pleased to announce the release of:
- apache-taverna-commandline 3.1.0-incubating
- apache-taverna-engine
This is a DRAFT article for discussion purposes only.
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-
incubatingRevised 2016-06-30
Introduction
Apache Taverna Engineincubating 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
). In addition, you can execute many Taverna 2 workflows (.t2flow
) , depending on which activities they require.
Support for executing Common Workflow Language workflows is planned. Please contact the dev@taverna mailing list for details.
Taverna Java API
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.
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.
In addition the above relies on these libraries which have been released earlier:
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 supportedare no longer supported in Apache Taverna.
– RShell
– Soaplab
– Biomart
They are now maintained (??) separately Their source code is available 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
