What is the ESCAPE Virtual Observatory?  

The Virtual Observatory is a framework built on International Virtual Observatory Alliance (IVOA) standards for the interoperable access to world-wide large astronomy data catalogues and services, that researchers can use to can access, reuse and publish data. Within the ESCAPE project WP4 CEVO is adapting, extending, and developing new IVOA standards according to the demands of the ESFRI partners. CEVO is an effective way to represent the European interests at the IVOA.  CEVO enables an ongoing exchange between standard developers, data providers, and scientific users. This is pursued through different channels and events.




         What can you do?

  • Make your data FAIR
