Abstract

The Astronomical Dataset Characterization Data Model (CharDM) defines and organizes all the metadata necessary to describe how a dataset occupies multidimensional physical space, quantitatively and, where relevant, qualita- tively, in such a way that they become interoperable. We present here a new version of the characterisation data model, with description of data interpretation aids from variablity of observations, together with new representations for polarisation and redshift axes. Complex datasets are also tackled.
