PCDD provides the information required for accessing clinical multimedia information directly from its source, i.e., PCDD feeder systems. In general, feeder systems update the directory in a bulk-load fashion. Each feeder system is associated with a dedicated gateway that facilitates data extraction from the feeder system. Gateways get data from the feeder system, map it to the model of the directory, and translate it into LDAP statements, which are stored in a standard LDAP modify file. Since feeder systems are in general heterogeneous, this gateway may take different forms.
