Analysis, Design and Realization of Metadata Managing System for Multimedia Resources

Abstract

For the description and management scientifically and in order and for the establishment of digital library information service system with our own features conform to international standards, we design and develop a set of system platform on the basis of multimedia resources. The multimedia resources metadata managing system supports the function of digital collection, processing, bibliography description, storage, organization and publishing of text, pictures or images, audio and video frequency and other multi-media information. The system must first define a set of metadata standard system according to the features of different resources and design metadata model describing these them, order metadata system templates and establish metadata application model through its models. The function of the system templates is to process, describe information resources when bibliographers establish some new multimedia resources on the basis of metadata system defined in advance by the system; secondly, the system describe the metadata of digital resources through metadata description template, identifying subject, classification and related data; thirdly, the system check, and publish data information through data checking and publishing model. During the period of the research of the multimedia metadata model and management system module, we use the domestic and overseas experience for reference. The choice of metadata, description of attributes, validity inspection of DTD and Schema, the standard of description classification, quotation of authority, XML and XSL data format and the upload data through the FTP all conform to the domestic and international standards. The system sets up multimedia resources element attribute descriptive frame on the base of the DC and also provides standard Chinese Library Classification system and authority name control. The bibliography description process can be easily realized with the use of visual operational interface. The pull function should be convenient for bibliographers. The system is highly integrated with other digital library system such as virtual reference service system and MELINETS (Modern Electronic Library Information Net System) of BUPT (Beijing University of Posts and Telecommunications). Mature techniques have been employed during the developing period. Open and standard interface are provided and various data exchanged are supported. The metadata database and object database can be effectively managed with the system management module. The realization of the design and techniques, the standardization and automation of multimedia resources in bibliography description are strengthened and the working efficiency improved.
