Research On Description And Application Of Information Resources In Digital Library Based On XML/RDF

Since the last decade of the 20th century, the computer network and communication technology have been developing very fast. In order to improve the efficiency of processing, organizing, manipulating and transmitting large numbers of information resources, theories and technologies on Digital Library (DL) have been developed and then become the aim and direction of traditional library. DL, a brand-new concept and practice, characterized by the digitized process, storage, management and transmission, has achieved the information services beyond the physical space by means of multi-media access, Telnet transmission intelligent retrieval and seamless links across different databases.DL is a new management mode of information resources. The foundation and precondition of DL's services is digital, multi-media information resources. The core of DL's construction is the building of information resources. The construction of information resources in DL includes the digital of resources stored and the storage of Internet resources. The traditional library describes resources in MARC, and the users gain the correct MARC data merely by using OPAC and Z39.50, this is the main reason that users could not obtain the MARC data with common search engine. On the other hand, with the development of WWW, Internet resources have been becoming more and more, but the search of resources becomes difficult under the circumstance of millions of Internet resources. And then, how to describe resources in metadata and to resolve the existence of metadata framework is main problem in building the information resources.In this dissertation, firstly, the form, evolvement, development of the concept of DL, the systematic framework and the challenge in building DL have been discussed; Secondly, the theory of information resources in DL has been analyzed, and the problem and framework of metadata have been studied; then, the conversion of description of MARC has been studied; At last, the storage, search and dynamic display of documents based on XML/RDF have been discussed.
