Taverna Project Retired

tl;dr: The Taverna code base is no longer maintained and is provided here for archival purposes.

From 2014 till 2020 this code base was maintained by the Apache Incubator project Apache Taverna (incubating) (see web archive and podling status).

In 2020 the Taverna community voted to retire Taverna as a project and withdraw the code base from the Apache Software Foundation.

This code base remains available under the Apache License 2.0 (see License below), but is now simply called Taverna rather than Apache Taverna (incubating).

While the code base is no longer actively maintained, Pull Requests are welcome to the GitHub organization taverna, which may infrequently be considered by remaining volunteer caretakers.

Previous releases

Releases 2015-2018 during incubation at Apache Software Foundation are available from the ASF Download Archive https://archive.apache.org/dist/incubator/taverna/

Taverna Common Activities

Common Activities to be invoked as part of Taverna workflows.

Note that this module relies on other Taverna modules for the actual workflow execution.

Contribute

Any contributions received are assumed to be covered by the Apache License 2.0. We might ask you to sign a Contributor License Agreement before accepting a larger contribution.

Prerequisites

• Java 1.8 or newer (tested with OpenJDK 1.8)
• Apache Maven 3.2.5 or newer (older versions probably also work)

This code relies on other Taverna modules, which Maven shuold automatically download from Apache's Maven repository; however you might want to compile these yourself in the below order:

• taverna-language
• taverna-osgi
• taverna-engine

Please see the <properties> of this pom.xml to find the correct versions to build.

Building

To build, use

mvn clean install

This will build each module and run their tests.

Building on Windows

If you are building on Windows, ensure you unpack this source code to a folder with a short path name lenght, e.g. C:\src - as Windows has a limitation on the total path length which might otherwise prevent this code from building successfully.

Skipping tests

To skip the tests (these can be time-consuming), use:

mvn clean install -DskipTests

If you are modifying this source code independent of the Taverna project, you may not want to run the Rat Maven plugin that enforces Apache headers in every source file - to disable it, try:

mvn clean install -Drat.skip=true

Modules

Each module implement a particular type of Taverna Activity.

• taverna-beanshell-activity: Taverna Beanshell Activity, runs Beanshell scripts.
• taverna-external-tool-activity: Taverna External Tool Activity, run command line locally or over SSH
• taverna-interaction-activity: Taverna Interaction Activity, ask questions to the user through a browser
• taverna-rest-activity: Taverna REST Activity, invoke RESTful HTTP(S) web services based on a URI template.
• taverna-spreadsheet-import-activity: Taverna Spreadsheet Import Activity, imports from CSV, Excel and OpenOffice.
• taverna-wsdl-activity: Taverna WSDL Activity, invoke WSDL-described SOAP services.
• taverna-wsdl-generic: Taverna WSDL-generic Library, library for parsing WSDL and calling SOAP services
• taverna-xpath-activity: Taverna XPath Activity, select XML fragments using XPath expressions

Export restrictions

This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.

The following provides more details on the included cryptographic software:

• taverna-rest-activity depends on Apache HttpComponents Client, and can be configured to initiate https:// connections.
• taverna-wsdl-generic and taverna-wsdl-activity use Java Secure Socket Extension (JSSE) and depend on Apache WSS4J, Apache XML Security for Java for accessing secure SOAP Web Services.
• Taverna Common Activities depends on the Taverna Engine Credential Manager API for management of username/password and client/server SSL certificates.
• taverna-interaction-activity depends on Jetty, which includes UnixCrypt.java for one way cryptography, and can be configured for SSL encryption using Java Secure Socket Extension.
