Developing Driver Modules

Verity provides limited C-language APIs for developing low-level driver modules for the Verity DDA layer. Most driver modules (gateways, document filters, and locales) are developed by Verity itself.

The following are the DDA-level C APIs:

Gateway Driver APIs. Support the development of custom gateways that access new kinds of information repositories.


Documented in the Verity Gateway Developer’s Kit Programming Reference.

Custom Filter APIs. Support the development of custom document filters that read and process new document formats.
