ESCAPE contributions to IVOA

Jump to: navigation, search


The International Virtual Observatory Alliance (IVOA) was formed to develop standards for interoperability of astronomical data within the community, with an aim on archives services, and clients querying these services. Found in 2002, the IVOA was far ahead of time and established standards that today would be considered to be FAIR. Contribution to the IVOA through ESCAPE is important on many levels, from the organisational level to the development in standards or software for data services and clients.


The IVOA TCG is formed by the Chairs of the Working and Interest Groups and includes the IVOA chairs and vice-chairs. Below table shows the contributions of ESCAPE partner institutes to the TCG. To find the list of all TCG members, go here
