The Design and Implementation of Library Information Management System

Under the circumstances of information developing, the digital library which provides knowledge exchange, share and long-term preservation functions and services, as the main implementer of interoperability of heterogeneous resources and services under the network environment, has semantic interoperability function, which is not only driven by objective environment and objective trend, but also one of the functions for its own survival development.Since the unordered flood of information on the Internet increases, the heterogeneous information system under the distributed environment emerges in endless, at the same time, the requirements for information service quality of users constantly improve, semantic interoperability must become the core functions of digital library.Through literature research, summary and personal practice, this paper attempts to completely and systematically comb the concept and technology of semantic interoperation of digital library.
