<H1> DM work package : Characterisation Data Model</H1>

<H2>Goal </H2>
   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.

<H2>Characterisation 1 Legacy</H2>
    * Characterisation Data Model effort led to a publication of a version 1 of the Data Model in 2008 [[CharacLegacyPage][(see legacy page)]]

<H2>Towards Characterisation version 2</H2>

    From September 2007 on, a new effort started to take into account both dissemination of the model in Data centers and completion of the model for some complex use cases.
