At the core of the VO is a set of standards developed within the International Virtual Observatory Alliance (IVOA) to support good data management and interoperability
simulated data
– Data Model; Uniform Content Descriptors
– Data Access Layer; VO Query Language
services
– IVOA registry
– SAMP – VO-enabled tools and services can interface seamlessly with VO-enabled archives worldwide
11
Alliance (IVOA) today has 21 member projects
– Affiliated projects seek funding from their national agencies
