LOFAR and the VO Meeting

Date and location

18 November 2016, Observatoire Astronomique de Strasbourg, 11 rue de l'Université

The meeting will begin at 9:00


Discussion of the two topics identified as priorities by LOFAR with respect to the VO:

  1. Get a better understanding of the state of the art regarding the expression of interferometric data in the VO, visibilities in particular. The point is to examine how the VO standards, especially the new ones such as SIAP 2.0, could be relevant to LOFAR data model.
  2. Examine the possibility to express LOFAR data model using VO DM formalism.

Discussion of HiPS visualisation is also of interest for LOFAR but will likely be potponed to another F2F or teleconference meeting.
