1. Kepler includes contributors from GEON, SEEK, SDM Center and Ptolemy II, supported by NSF ITRs 022567 (SEEK), EAR-0225673 (GEON), DOE DE-FC02-01ER25486 (SciDAC/SDM), and DARPA F33615-00-C-1703 (Ptolemy). The installer for Kepler 1.6a is available for download at http://kepler-project.org Kepler is a system for design and execution of scientific workflows. Built on top of the powerful Ptolemy II modeling tool, Kepler allows scientists to design, prototype and execute in a single environment a wide spectrum of scientific workflows, ranging from high-level domain-specific ones (e.g.mineral classification) to low-level “ Grid workflows ”. With an intuitive drag&drop interface, Kepler is an effective tool for scientists who need a flexible and extensible workflow environment. Geosciences problems often require complex data access and computational analysis. These can be composed in a meaningful order into a geosciences workflow. Kepler provides the following components to assist geologists in scientific discovery: Data handling features: Data extraction and registration workflows Metadata based data search and access Local and remote data access: Relational and Geospatial databases Web service data access (query) Storage Resource Broker (SRB) File Transfer Protocols: GridFTP, SCP, SRB Processing tools: Generic web service client Legacy application integration via Shell- Command actor e.g. R, GMT Browser user interface for visualization and user interface Domain specific applications: ArcIMS services Point in polygon classification algorithm Grid interpolation algorithms Workflow prototyping tool (for napkin drawings) Local and remote execution environments: Local Kepler application Execution from a portal environment Coming soon: peer to peer execution model Future Directions: A workflow for integrating seismic events focal mechanisms (beach balls) with ArcIMS image services Mapping workflows onto the grid, using Pegasus, to handle massive datasets (e.g., LIDAR) A unified framework for accessing dataset and registering workflow products within the portal Additional portal execution support GRASS support Kepler as a Modeling Tool: Gravity Modeling Design Workflow Integrating heterogeneous gravity depth sources to create a 3-D gravity model.
