The Study Of XML-based Network Information Organization

Along with the development of internet and every kind of LAN, information network has come true. People oriented of information organization and service request that information service system should follow the principles of practicability and accessibility, making the best of newly technology and accumulated experience, shrewdly organizing and processing information to wholly satisfy user's information demand. The idea of XML-based network information organization, which combined the concepts of XML and information integration, provides a new way to improve the condition of network information organization.Based on SGML and HTML, XML is a brand new markup language. XML document interior adopts tree-form to describe data, can express any kind of structural and non-structural data, possessing well data storage format and strong extensibility, and can be used in all platform no matter the type of application, it's very convenient for network data exchange, so it possesses good versatility and flexibility.With XML structural advantage, we can use XML technology system to define and markup information gathering mode and its segment's name, abstraction, links, combination, integration, and realize the definition and markup of metadata and knowledge organization system, and realize data conversion and define the mechanism of data display. XML is also widely used in the query mechanism of information resource.XML technology system based on XML increasingly becomes the foundation of organizing information, processing information, exchanging information. According to the special demands in different areas, XML provides a tool to define the appropriate makeup language in every special area. W3C and other application areas put forward a series of standards: XHTML, SVG, SMIL, MathML and so on, it's successful application of XML in information organization.As its unique metadata trait, XML can fundamentally realize the library-stored information to be expressed in Web environment, in format expression, content display, transmission, query and display. XML can contribute to realize artificial search engine, data mining and data analysis in digital library, to realize user individuation service, to backup each information system achieving seamless exchange, virtual integration and...
