This workpackage is aiming at defining the high level metadata necessary to describe the astronomical data sets on their physical axes, either observed or simulated, for various types of data like 2D-images, data cubes, X-ray event lists, IFU data, etc.. The goal is to provide an abstraction which contains structured information for all these types of data so that discovery and interpretation is feasible in a general framework, and can be used jointly for science cases. The model aims at facilitating the manipulation of heterogeneous data in VO portals. A VO Characterization instance can include descriptions of the data axes, the range of coordinates covered by the data, and information on the data sampling and resolution on each axis. These descriptions are in terms of physical variables, with the specific instrumental signature abstracted away.
