Currently, the format of the map files is SGML and each collection map file conforms to a simple DTD (other ways of mapping terms, such as a database where one could map from one column's data to another are possible and have been considered for implementation). The map is read into a TerminologyMapper object during the running of the middleware after which the CGI program can at any time request of the object the mappings for terms. Each mapped item and its various terms are contained within a <MAPPING> element.

Each mapping element in a map file consists of the following:
