DrUI （Digital Resource Unique Identifier）is designed as a “barcode solution” to identify various network objects including text, images and multimedia. With its robust, persistent and unique character, an viable interoperability between different applications can be achieved in an Internet resolving system. The author firstly scans the current research and employment status by introducing IDF’s DOI solution and Tsinghua Tongfang’s unique code in its full-text journal databases, then from the viewpoint of the library consortia, the author compare three different methods to develop a resolving system in China mainland. At last a strategic plan of DrUI developing come into being and related issues are discussed such as management of DrUI,technical platform and standards selection.

This article introduced a design project of Z39.50 server system in Vip Database. This project has two resolving methods: one based on TCP/IP, and the other based on HTTP. Then the author compared these two methods. This server system breaks through the application of traditional Z39.50 in providing only bibliographic data service. While it provides E-journal data service. So it is the specialty of this project.

This article introduces the Ontology in retrieval systems on basis of analyzing Natural Language Information Retrieval (NLIR). In NLIR, Ontology can improve the quality of indexing and user interface, and help to solve the problems in NLIR as well. Finally, it addresses further problems to be dealt with of Ontology in retrieval systems.

With the rapid development of Digital Library, the interoperability arises as a very important problem to be resolved. As a “low entry” protocol, OAI-PMH is able to design and implement a interoperable framework based on metadata harvesting openly. After introduce the OAI-PMH specification and OAI architecture, this paper elaborates the design and implementation of metadata search engine based on OAI.

This paper analysises the characteristic and the hinge of fulltext database on the base of the analysis of database technique.then it introduces Lucene search engine,a toolkit of fulltext retrieval,and employ it in the application.Writers research the index and search technique of fulltext database, raise and fulfill a fulltext database which dispense with the background database. In reality,the space-time efficiency of index and search is very well.

Aimed at the limitation of network navigation and search services, the paper concludes four integration models of subject resources; then points out design thoughts, design principles and system framework of subject resources integration based on Website construction; finally demonstrates the realization scheme of organization and development for subject resources.

This paper discuss the important function of transparent proxying in library local area network, concern in detail the way to implement transparent proxying with iptables and squid on linux system and introduces concrete methods with library local area network as a case in point.

This paper introduce how to use the function of NAT and the function of port map of NGFW3000 to insure the realization of Online Cataloguing and OPAC in intranet.

This study investigates the state of education for digital libraries. For this study, a Web survey was conducted of syllabi of courses on the subject of Digital Libraries (DL).  Similarities and differences on such subjects as teaching emphases, course outlines, textbooks and assignments were compared.  The majority of classes now contain a “hands-on” element, a practical component of the course that requires that the students interact with Digital Libraries.  Not all of the course contents are up-to-date in the field of library and information technology.  While the quality of DL education seems to have advanced at those schools that at institutions that offer classes with “hands-on” requirements, the educational approach at many of the “hands-off” universities seems somewhat technophobic and overly dependent on outdated pedagogical methods. Those students who have received practical experience with digital libraries, like those provided in the “hands-on” courses, appear to the best served for future practice in the field of librarianship and being more marketable as a Specialists or “Dynamic Librarians”.

The paper indicates the meaning of constructing self-help multimedia network classroom which utilizes the technology and document resources of university libraries and campus network. Taking the library of Jilin university as example, discusses on the network environment, software and hardware conditions, in addition, also probes into some relative problems, such as the design of the network classroom’s function, web pages and courseware management, courseware image etc.

According to the Descriptive Rules of Chinese Book’s Name Authority Headings and the features of authority fields in INNOPAC system at the Library of TSU, we discuss the keys to the main field description of the authority records in Chinese books, and also give some advice on how to make a standard authority record。

This Paper give a discussion on the development of agro-info-resource application system and the construction of backstage database with focusing on the design and realization for the functional         module soft data consulting and information releasing etc. Based on B/S operating structure and under Windows 2000 Server+ASP+Access 2000 model as well as by means of visible Dreamweaver MX 2004.This system is characterized by friendly medium, stability and good result, and assembles the functions of data releasing and consulting, maintaining ,managing, etc.

ASP.NET is a powerful server-side Web script programming envirenment.This article describes how to use ASP.NET, SQL Server and  so on to develop thesis submission system. As a result ，graduates can submit their thesises on line.

The journal catalog reporting service conducted in our institute is first introduced here. To manage journal catalog information acquired from the Internet, we realize the automatization of catalog editing by making use of the Visual C++ programming language. In this way, computers will automatically manage most of the mechanical editing and typesetting work handled manually before. Reports of journal catalogs provided for users are thus concise, clear and easy for reading and inquiring. Not only is the designing thought introduced here, the realizing method and specific using of each function of the system are also discussed.

With the rapid development of computer technology and enterprise information, the application of MIS(Management Information System) has made a great process, it become more and more important to share and exchange information. To exchange and share information among these heterogeneous databases, so that users can manage and apply these heterogeneous databases just like a single data source, this paper put an idea of heterogeneous databases integration based on XML and ADO.NET, and also make a detailed exposition of key technology.

This paper analyses the data of the log file in the library apache server based on the standard format of server log file. With the data mining technology, the using status of the library Website are studied.

This thesis  carries on  an  analysis  about  how to  quarantee  the  effective, steady  and  normal  going of  library network,concerning  management  on  network  breakdowns,  ways and  steps  to  fix  network breakdowns,common orders to test library network,general ways to clear network stoppages,etc.

This article explains how to contruct the virtual private network of Wenzhou shared resource on the basis of MPLS VPN technology, and logically to link the public library, community library and the shared project of skeleton center network into a uniform Intranet to realize information resource share of wenzhou public library and improve the ability of information service in county library.
