The KRM's research result search system has been designed with the application of hierarchical and associative meta data structure called "Functional Requirements for Bibliographic Records(FRBR)".

The data contained in DB has hierarchical structure in four levels such as the research task (work level), research results (expression level), original text contents (manifestation level), and location information (item level) and associative structure that allows relevant data to connect with each other.

Accordingly, KRM’s research result search system makes hierarchical, horizontal searching and browsing possible among the relevant data.
