Parts of a VO
• All databases listed in Registries, or ‘Yellow Pages’ • Databases selected via their Metadata • Data grabbed from selected database using Grabbing
Services • Data analysed using Manipulation Tools
• Depends on:
– Agreed standards – Services and applications which understand VO rules – Middleware which glues everything together

Applications • Virtual World Forest Observatory in which:
– Users all over the world access multiple attribute data and multi-sensor data (e.g. Landsat, LIDAR etc.)
– BUT data stay in their host databases – Local people can validate maps
• Combine Spatially Decentralized Databases – National forest inventories by provinces in large countries – Citizen observatories in hundreds of towns etc.
• Combine Multiple Databases in Large Groups – International research projects – Research councils – Mapping organizations

Next Steps
• Demonstrate prototype virtual observatory at February Conference
• Agree on initial standards at Conference – Metadata
– Table formats
• Establish Working Group to agree on further standards over time
