1. Using Sakai to Support eScience Sakai Conference June 12-14, 2007 Sayeed Choudhury Tim DiLauro, Jim Martino, Elliot Metsger, Mark Patton and David Reynolds Sheridan Libraries Bob Hanisch Space Telescope Institute Alex Szalay and Ethan Vishniac Physics and Astronomy Johns Hopkins University A pilot project aimed at preserving, curating, and enabling access to digital data and associated electronic journals content.

2. The Virtual Observatory The Virtual Observatory enables new science by greatly enhancing access to data and computing resources. The VO makes it easy to locate, retrieve, and analyze data from archives and catalogs worldwide. The VO is about data discovery, access, and integration. The VO is NOT a huge centralized data repository. The VO provides standard protocols for obtaining data from distributed collections. The VO is national (US NVO) and international (IVOA).

3. The data preservation problem Research communities publish peer-reviewed journal papers that describe highly processed data. Long-term preservation and curation systems for digital journal content, including the digital data presented only graphically, are not currently in place. The research cannot be verified and the results cannot be easily compared to other data in order to broaden impact. Public funds invested in scientific research do not have maximum return on investment. Essential legacy datasets may be lost.

4. Approach Integrate digital data management into the publication process (data capture, review, metadata tagging and validation, storage). Exploit emerging information technology standards for managing distributed data collections, including digital journals. Provide multiple access methods to digital data to maximize visibility and re-use. Exploit information management and curation experience in the university libraries and build on long-term institutional commitments to preservation.
