WIT offers 40 pre-defined bibliographic fields, and aliases to some of them.

You can define your own aliases (if you need to analyse lines yet ignored by WIT), and map them to WIT fields by appending them to the current alias list of the chosen field.

Please refer the configuration file (located in _INSTALLDIR_\Data\DataFormats, named "name-value-format.txt", and listed below) for more explanations.
