VisionA 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

SystemsA 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

Its accessible and reliable.Completeness

Its the most definitive source of information. Quality Assurance

It can be trustedUsability of Data Formats

One click rendering and analysisPreservation

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 nowCross discipline usage and seamless integration remain a

challenge to be met.
