Aquilent, Inc. proposes to support the effort of Virtual Space Physics Observatory (VSPO) by developing services to expand the VSPO search capabilities, developing tools that facilitate metadata conversion and input, and integrating existing standalone visualization applications to operate in the VSPO environment. This proposal seeks to: ? Enable scientists to execute advanced search queries. (Queries which rely on more then product description metadata) ? Enable scientists to utilize VSPO middleware capabilities directly from visualization applications. ? Develop services that provide support for advanced search queries. Integrate these services into the VSPO architecture. ? Develop a metadata editor tool, designed to simplify metadata entry/mapping associated with describing data products. ? Integrate standalone visualization applications such as ViSBARD to work seamlessly with VSPO middleware.
