The Common Data Model (CDM) is the underlying data structure of the EDIT Platform for Cybertaxonomy, representing a complete model of data used in biological taxonomy and systematics. CDM-light is a set of relational tables produced by one of the export functions of the EDIT Platform. As compared to the CDM itself, the relational model is simplified and data are partially aggregated. CDM-light may be used as a transfer format, to generate statistics about the data in a CDM database, to control data quality, or to produce document-type output from CDM databases
