Taverna retired from Apache Incubator
tl;dr: The Taverna code base is no longer maintained and is provided here for archival purposes.
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While the code base is no longer actively maintained, Pull Requests are welcome to the GitHub organization taverna, which may infrequently be considered by remaining volunteer caretakers.
Releases 2015-2018 during incubation at Apache Software Foundation are available from the ASF Download Archive http://archive.apache.org/dist/incubator/taverna/
Releases 2014 from the University of Manchester are on BitBucket https://bitbucket.org/taverna/
Releases 2009-2013 from myGrid are on LaunchPad https://launchpad.net/taverna/
Releases 2003-2009 are on SourceForge https://sourceforge.net/projects/taverna/files/taverna/
Binary JARs for Taverna are available from Maven Central https://repo.maven.apache.org/maven2/org/apache/taverna/ or the myGrid Maven repository https://repository.mygrid.org.uk/
Workflow engine for Taverna.
The engine executes a Taverna workflow, defined using Taverna Language.
This product includes software developed at The Apache Software Foundation.
The NOTICE file contains any additional attributions as well as details about embedded third-party libraries and source code.
Any contributions received are assumed to be covered by the Apache License 2.0.
Please see the
<properties> of this pom.xml to find the correct versions to build.
To build, use
mvn clean install
This will build each module and run their tests.
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.
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
The Taverna Engine modules are generally split into
-api modules contain Java interfaces, abstract classes, and minimal dependencies while
-impl modules contain the corresponding implementation(s).
These modules include utilities used by the above, or for test purposes:
These modules include structural workflow activities:
See the separate release of taverna-common-activities for activities that invoke Beanshell, WSDL, REST and command line tool services.
These modules are experimental:
These modules are not yet fully updated to Taverna 3 (contributions welcome!):
See the taverna-engine JavaDoc for more details.
This section shows how different Taverna Engine module are involved when running a Taverna workflow, e.g. from the Taverna Command Line.
There are two layers of Taverna Engine:
t2.core) is the orchestrating part of the Taverna Engine. Its Activity is implemented by multiple plugins depending on the activity type.
.t2flowfile using WorkflowBundleIO from Taverna Language.
Bundlewith inputs. A workflow run id
Stringis returned for subsequent calls.
Activityimplementations, allowing pass-by-reference where supported, with conversion to strings and bytes if needed.
The OSGi services should be discoverable as Spring services, e.g., by adding the following code to your
<beans:beans xmlns="http://www.springframework.org/schema/osgi" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd"> <reference id="executionService" interface="org.apache.taverna.platform.execution.api.ExecutionService"/> <reference id="runService" interface="org.apache.taverna.platform.run.api.RunService"/> <reference id="credentialManager" interface="org.apache.taverna.security.credentialmanager.CredentialManager" /> <reference id="databaseConfiguration" interface="org.apache.taverna.configuration.database.DatabaseConfiguration" /> <reference id="databaseManager" interface="org.apache.taverna.configuration.database.DatabaseManager" /> </beans:beans>
You might want to combine these with the Taverna OSGi services.
