The IAU WG Virtual Observatory is the standard-bearer of the International Virtual Observatory at IAU, and it is the primary point of contact between the IVO and the IAU. Its primary role is to provide an interface between IVOA activities, in particular IVOA standards and recommandations, and other IAU standards, policies, and recommandations. In particular, it raises VO-related topics (e.g. symposia, GA sessions, ...) that should be handled by the IAU (Commission 5, Division XII and executive level). It is responsible for approving the standards proposed by IVOA, after checking that there has been a process of consultancy according to the IVOA procedures, and that the proposed standards are consistent with other IAU approved standards (e.g., FITS, coordinate standards, etc.).
