AB: Several search and retrieval systems for space physics data are currently under development in NASA's heliophysics data environment. We present a case study of two such systems, and describe our efforts in implementing an ontology to aid in data discovery. In doing so we highlight the various aspects of knowledge representation and show how they led to our ontology design, creation, and implementation. We discuss advantages that scientific reasoning allows, as well as difficulties encountered in current tools and standards. Finally, we present a space physics research project conducted with and without e-Science and contrast the two approaches.
