Introduction to the RDM API

This chapter describes the use of the search engine Resource Description Manager (RDM) API to access the search engine and its database. The RDM API provides routines to parse, modify, and create resource description messages (RDMs) using C.

The robot generates RDs and saves them to the search engine database. You can retrieve the RDs in SOIF format, use the RDM API to modify them, and then have the search engine import them back.

The RDM API is defined in the rdm.h file in the following directory in your search engine installation directory:

PortalServer-base/sdk/rdm/include

This chapter is restricted to discussing the use of C functions that come with the search engine RDM API. Therefore, it is strongly recommended that you have a basic understanding of the C programming language.
