The ADL system currently includes two collection servers, the ADL catalog and the ADL gazetteer. Accommodating their quite different schemas has been a good test of our search bucket mapping strategy (i.e., congruent views in both the catalog and the gazetteer). Both the catalog and the gazetteer are implemented as Informix (version 9.13) databases. The only Informix-specific features that we currently exploit are the MapInfo spatial data types, and their associated operators and indices, to implement the ``location'' search bucket.
