Practical Interoperability in the Virtual Observatory
The Virtual Observatory (VO) is an international effort to run and develop a federated data infrastructure in Astronomy that is held together by a set of data and protocol standards. Consisting of a Registry, some 30000 interoperable services (which roughly correspond to data collections) comprising hundreds of millions of datasets (spectra, images, and the like) and hundreds of billions of table rows, as well as a set of clients and libraries consuming these services, it is widely used in the astronomical community. In this contribution, I will give a condensed overview of the technologies behind the VO, with a particular emphasis on how the VO is not just a platform but a truly global infrastructure jointly shaped by data providers, software authors, and science users.
