The open-source CDK Taverna 2.0 project based on the "Pipelining Technology" idea tries to address the advantages of software libraries and sophisticated information systems.
The project combines several other open-source projects:

  • The Taverna workbench as a workflow container[1].

About The CDK-Taverna 2.0 Project

Pipelining or workflow tools allow for the LegoTM-like, graphical assembly of I/O modules and algorithms into a complex workflow which can be easily deployed, modified and tested without the hassle of implementing it into a monolithic application.
The CDK-Taverna project aims at building an open-source pipelining solution through combination of different open-source projects such as Taverna[1] , the Chemistry Development Kit (CDK)[2][3] or Bioclipse[5]. A first integrated version of CDK-Taverna was recently released to the public[6].
Current developments in CDK-Taverna refactor all workers (activities) as well as the complete setup on the basis of Taverna 2.2 and CDK 1.3.7 which themselves introduce major improvements to the whole platform. In addition the CDK is enhanced with specific functions and options for reaction enumeration based on a reaction template and corresponding reactant libraries. Reaction enumeration supports combinatorial chemistry approaches in the drug discovery process of the pharmaceutical industry. The CDK enhancements are applied and illustrated by corresponding CDK-Taverna-workflows.

Who Did It

CDK-Taverna was originally conceived by Christoph Steinbeck(1) and Achim Zielesny.(2) The developing was done by Thomas Kuhn and co-developed by Egon Willighagen(3). The ported and extended CDK-Taverna 2.0 version for Taverna 2.2 is currently under development by Andreas Truszkowski(1,2) and is well supported by Christoph Steinbeck(1), Achim Zielesny(2) and Egon Willighagen(3).

CDK-Taverna 2.0 Features

There are more than 180 activities in preparation:

For an overview and descriptions of the available activities click here.

CDK-Taverna 2.0 works on Microsoft Windows and Mac OS X 32/64bit operating systems and will be released soon.

Workflows

Workflows tackle the complexity of scientific experiments and applications. They give the scientist the power to process their experimental data without any programming knowledge. Therefore various types of tasks can be solved by simple modules which are combined to build powerfull processing networks. Each module delivers only a little fragment of functionality but combined they are able to perform more and more complex tasks. The possibilities for such workflows are almost infinite.
A workflow consists of a sequence of connected steps. This steps are composed of three layers:

  1. The input layer
  2. The processing layer
  3. The output layer
