Vision A data cloud built with open metadata, open services, open sharing and standard formats. • This shifts the data focus so that:“What” is more important than “Where”. (the essence of a cloud) • Virtual Observatories (aggregators) are the interface to the cloud.
Guiding PrinciplesFor Science Information Systems • A System with: • Involvement of scientists in each stage of the process • Openly accessible data that are independently scientifically usable. • Every resource has a Universal Resource Identifier (URI). • Preserve all available knowledge about a resource. • Provenance • Caveats • Annotations • Associations • Publications … Trusted archives

Challenges • Robustness • Its accessible and reliable. • Completeness • Its the most definitive source of information. • Quality Assurance • It can be trusted • Usability of Data Formats • One click rendering and analysis • Preservation • Keeping things safe for the future. • Seamless • Easily transition from data discovery to evaluation to analysis to publication.
Meeting the Challenges • It takes effort to meet the challenges • This is best met as a social effort (many people working collectively) • Many of the challenges are being met by today’s virtual observatories in: • Astronomy (IVOA) • Planetary (PDS) • Heliophysics (HPDE) • Earth Science () • Further refinement and enhancements are happening now • Cross discipline usage and seamless integration remain a challenge to be met.
