Kepler

“Scientists in a variety of disciplines (e.g., biology, ecology, astronomy) need access to scientific data and flexible means for executing complex analyses on those data. Such analyses can be captured as 'scientific workflows' in which the flow of data from one analytical step to another is captured in a formal workflow language. The Kepler project's overall goal is to produce an open-source scientific workflow system that allows scientists to design scientific workflows and execute them efficiently using emerging Grid-based approaches to distributed computation.

Kepler is based on the Ptolemy II system for heterogeneous, concurrent modeling and design. Ptolemy II was developed by the members of the Ptolemy project at UC Berkeley. Although not originally intended for scientific workflows, it provides a mature platform for building and executing workflows, and supports multiple models of computation.”

The Kepler project is a cross-project collaboration to develop open source tools for Scientific Workflows. Currently this collaboration includes contributing members from the following projects:


 * SEEK: Science Environment for Ecological Knowledge
 * SDM Center/SPA: SDM Center/Scientific Process Automation
 * Ptolemy II: Heterogeneous Modeling and Design
 * GEON: Cyberinfrastructure for the Geosciences
 * ROADNet: Real-time Observatories, Applications, and Data Management Network
 * EOL: Encyclopedia of Life
 * Resurgence
 * CIPRes: CyberInfrastructure for Phylogenetic Research
