The Digital Sky Project
National Virtual Observatory (NVO), 2 micron all sky survey (2MASS)
Astronomy, computational astronomy
Significant computing capabilities are required to support computational astronomy, including large scans over data collections, data mining and cataloguing. This project combines grid data-intensive computing and technologies; in addition to remote data access and analysis.

Nirvana was utilized to provide distributed data access and metadata management. The standard open source FITS library was modified to provide a transparent Nirvana data access for NVO applications. Several mosaic and data cataloguing software packages were written by astronomers to support this effort.
The project completed on time and on budget. Data ingest and sorting was very successfully. JPL, Caltech and IPAC created mosaics on demand and cataloguing applications in later phases.
