Kepler

"The Kepler Project is dedicated to furthering and supporting the capabilities, use, and awareness of the free and open source, scientific workflow application, Kepler.  Kepler is designed to help scien­tists, analysts, and computer programmers create, execute, and share models and analyses across a broad range of scientific and engineering disciplines.  Kepler can operate on data stored in a variety of formats, locally and over the internet, and is an effective environment for integrating disparate software components, such as merging "R" scripts with compiled "C" code, or facilitating remote, distributed execution of models. Using Kepler's graphical user interface, users simply select and then connect pertinent analytical components and data sources to create a "scientific workflow"—an executable representation of the steps required to generate results. The Kepler software helps users share and reuse data, workflows, and compo­nents developed by the scientific community to address common needs.

The features include:

Kepler is based on the Ptolemy II system, a mature platform supporting multiple models of computation suited to distinct types of analysis (processing sensor data, for example, or integrating differential equations).

Kepler workflows can be nested, allowing com­plex tasks to be composed from simpler components, and enabling workflow designers to build re-usable, modular sub-workflows that can be saved and used for many differ­ent applications.

Kepler workflows can leverage the compu­tational power of grid technologies (e.g., Globus, SRB, Web and Soaplab Services), as well as take advantage of Kepler’s native support for parallel processing.

Kepler workflows and custom­ized components can be saved, reused, and shared with colleagues using the Kepler archive format (KAR).

Kepler ships with a searchable library containing over 350 ready-to-use processing components ('actors') that can be easily customized, connected and then run from a desktop environment to perform an analysis, automate data management, and integrate applications efficiently.

Kepler's Component Repository provides a centralized server where components and workflows can be uploaded, downloaded, searched and shared with the community or designated users.

Currently, Ke­pler has support for data described by Ecological Meta­data Language (EML), data accessible using the DiGIR protocol, the OPeNDAP protocol, DataTurbine, GridFTP, JDBC, SRB, and others."
