Xml Technology Is Applied Research In The Digital Library System

XML,a pivotal technology to developing Digital Library,belongs to top front area in present IT industry in the world. In China ,XML related research is just in the beginning.Based on full study of XML related development specifications and key technologies of Digital Library,this paper aims at research on resource organizing technology and construction of kernel MetaData in Digital Library system. After profound study on Dublin Core,a broadly identified MetaData standard for traditional library catalogs,the paper advanced a basic MetaDala in XML format for our experimental Digital Library system,along with i Is data structure requirements and DTD file specification. In the experimental Digital Library system,all types of MetaData and object contents are incorporated into a uniform management system based on XML and XML based RDF definitions,which ensures the integrity and inter_operational abi I i t.y of the MetaData. More over,the paper goes deep into discussion on many aspects of MetaData solution,such as design thought,implementation framework and its evolution trend.To demostrate and validate the above research work,the author designs and implements an XML Based Scientific Papers Management System,which comprises three functions:MetaData extraction and input ,MetaData edition and retrieval,MetaData integration with rational database. The successful storage and manipulation of XML formalized MetaData in this system provides successful experiences for further development of practical Digital Library system.Finally,a summery is made on the author' s study and development work so far ,and further research schedule is also planned in this paper.
