Bottom Line
Kepler is a java-based application for scientists, analysts, and computer programmers create, execute, and share models and analyses across a broad range of scientific and engineering disciplines which operates 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.

The Kepler is a software which helps scientists, analysts, and computer programmers create, execute, and share models and analyses across a broad range of scientific and engineering discipline and users share and reuse data, workflows, and components developed by the scientific community to address common needs.
Kepler offers features such as composite actors which can now be opened in tabs instead of separate windows, new language actors and demo workflows for Javascript, Beanshell, and Groovy, Syntax highlighting for language actors, new control flow actors: IfComposite, LoopComposite and SwitchComposite, New RecordOperation actor to modify records, splash screen which now shows startup progress, change suites or install patches from the command line, create screenshots of workflows using the command line and HSQL upgraded to version 2.
Kepler inherits modeling and design capabilities from Ptolemy, including the Vergil GUI and workflow scheduling and execution capabilities and the actor-oriented modeling paradigm that separates workflow components ("actors") from the overall workflow orchestration (conducted by "directors"), making components more easily reusable where Kepler scientific workflows can operate at very different levels of granularity, from low-level "plumbing workflows" to high-level "conceptual workflows" that interlink complex, domain-specific data analysis steps.
Kepler uses a director or actor metaphor to visually represent the various components of a workflow where actors specify what processing occurs while the director specifies when it occurs. The Kepler Repository contains over 350 actors shipped with Kepler as well as additional components shared by users where the repository allows users to upload and download workflow components to and from a centralized server while placing components in the repository allows them to be searched and re-used easily.
