MEx: FITS keyword mapping

In order to search and find data of interest it is necessary to describe and catalog them in a homogeneous way. The MEx utility is supporting this task for astronomy data products like images and spectra that are stored in FITS format.

MEx extracts and transforms keywords and thereby removes the instrument and observatory signature. This is achieved by converting values to physical units and mapping them to standard vocabularies (UCD) and concepts (utype). Users may supply their own mapping and data models. Special purpose s/w modules can be hooked in where simple mapping expressions are not sufficient to compute the desired values. This makes MEx very flexible and versatile.

While the data model configuration is a setup configuration, mapping definitions vary with the data. A mapping editor comes into play to help writing and testing mappings prior to apply them running MEx.
