Abstract
Aquilent, Inc. proposes to support ad-hoc, content-based query and data retrieval from virtual observatories (VxO) by developing 1) Higher Order Query Services that will work together with the Virtual Space Physics Observatory (VSPO) effort. These services will enable scientists to generate derived quantities and event-lists interactively based on existing science data and existing temporal and phenomenal event lists, as well as perform discontinuity and correlation analysis of time series derived from local low/medium resolution datasets. The framework architecture will be designed so that it can be adapted and extended for application to other VxO's. 2) Develop a metadata/data access toolkit that enables visualization and data analysis clients to browse VxO resources directly and retrieve discovered data from the source (PI) archive and demonstrate the capability through extensions to the VSPO Gateway API using VisBARD. 3) Support the creation, validation, and maintenance of product description metadata for VxO's through simplified metadata management tools whose configuration is driven by the same XML Schema that defines the VxO's data model. The tools include a configurable metadata editor backed by a central repository and XSLT (eXtensible Stylesheet Language Transformations) utility scripts. The XSLT scripts enable generation of the tool configuration schema from a master XML Schema, output of product metadata that complies with the VxO data model, and partially automat
