Application Of Metadata Construction On Digital Library Business

With the development of Library entering the digital age,the service field has shifted from the traditional papery literature service to the two-way information service mode centered on digitalized and networked services.It has gained the attention of library and related research institutes that the original library resources identification system has been unable to meet the new era of digital resources collections reveal requirementswhich showed excellent characteristics and management of metadata in digital information revealed in the library,many domestic and foreign research institutions and libraries to carry out the research and exploration of metadata,and achieved some achievements,but the feasibility of metadata in the wide range of library resources at all levels to achieve a unified Library of did not get too extensive validation,revealing how to use unified metadata standard library to complete various collections of digital resources,has become the urgent problem in the library.Also known as the intermediate data and metadata intermediary data,is currently the library identification of library digital resources most application format,so this paper mainly focus on the business of digital library to carry out the key technologies of metadata and how the application is studied.The main research and design work is as follows:1.The research status of domestic and international metadata analysis,based on the metadata of digital resources and reveal the management principle and the related metadata standards,and for all types of digital resources in the present library metadata model and reveal the validation process.Through statistical analysis of the application of metadata to identify various kinds of digital resources,we verify the feasibility and applicability of metadata in the digital library resource revealing and management.2.In order the Sirsi Dynix Symphony platform and the National Library of TRS WCM 7 metadata warehouse platform for verification environment,to prove the establishment of Marc data to metadata mapping model,realize the conversion from Marc data to realize the mapping of metadata,metadata of the traditional literature resources of library management revealed,which verified the feasibility of metadata in the traditional literature service application.3.The main form of the carrier resources contained in the current digital library resources of electronic text,images,audio,video,multimedia resources database,establish metadata model,carry out verification metadata digital resources reveal and management;multi media resource library resources into multiple types of composite is a new requirement of the application of digital library resources,according to the structure the elements of compound database and content elements,establish metadata model,carry out verification metadata of multimedia resource library reveal and management analysis,and the validity of the solutions on how to improve the metadata of multimedia resource library reveal proposed.
