Taverna source code

Development, release and testing procedures

The procedures we follow when developing code and making Taverna releases.

Tutorials

Tutorials for developers to get started with working with Taverna or developing plugins for Taverna.

Taverna workflow architecture

Taverna home directory

Taverna home directory is used for runtime information specific to the current user or configuration settings specific to that user.

Taverna startup (installation) directory

Taverna startup (installation) directory is the directory where you installed Taverna and where you run it from.

Extension points

Extension points in Taverna are interfaces which can be implemented by different modules and plugins to extend and add functionality to the workflow engine and workbench.

SCUFL2

SCUFL2 is the proposed new mechanism for specifying Taverna workflows. SCUFL2 defines a model, a workflow bundle file format (.wfbundle), and a Java API for working with workflow structures. SCUFL2 is the workflow language for Taverna 3, and replaces Taverna 2's t2flow format.
