Apache Taverna Language is a set of APIs for workflow definitions (SCUFL2) and workflow inputs/outputs/run (DataBundle), as consumed and produced by the Apache Taverna (incubating) workflow system.
The API includes support for the legacy formats from Taverna 2 and Taverna 1, and therefore can be also used independently of Apache Taverna 3.
This product includes software developed at The Apache Software Foundation.
The file NOTICE contains any additional attributions and details about embedded third-party libraries and source code.
Please subscribe to and contact the [dev@taverna](http://taverna.incubator.apache.org/community/lists#dev mailing list) for any questions, suggestions and discussions about Apache Taverna.
To suggest changes to this source code, feel free to raise a GitHub pull request. 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.
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.

To build Apache Taverna Language, use:
mvn clean install
This will build each module and run their tests, producing JARs like
taverna-scufl2-api/target/taverna-scufl2-api-0.15.0-incubating.jar. Some of the experimental modules are not built automatically, to build them separately, run the same command from within their folder.
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 timeconsuming), use:
mvn clean install -DskipTests
If you are modifying this source code independent of the Apache 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
Apache Taverna Language is a Maven project, and the easiest way to use it is from other Maven projects.
Released binaries of Apache Taverna Language are published in Maven Central.

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.

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.
