Web service based spatial forest information system using an open source software approach

For technical and other reasons there is a dilemma that data providers cannot find an appropriate way to redistribute spatial forest data and data users who need spatial data cannot access and integrate available forest resources information. To overcome this dilemma, this paper proposed a spatial forest information system based on Web service using an open source software approach. With Web service based architecture, the system can enable interoperability, integrate Web services from other application servers, reuse codes, and shorten the development time and cost. At the same time, it is possible to extend the local system to a regional or national spatial forest information system. The growth of Open Source Software （OSS） provides an alternative choice to proprietary software for operating systems, web servers, Web-based GIS applications and database management systems. Using open source software to develop spatial forest information systems can greatly reduce the cost while providing high performance and sharing spatial forest information. We chose open source software to build a prototype system for Xixia County, Henan Province, China. By integrating OSS packages Deegree and UMN MapServer which are compliant to the OGC open specifications, the prototype system enables users to access spatial forest information and travelling information of Xixia County which come from two different data servers via a standard Web browser and promotes spatial forest information sharing.

A Dairy Industry Information Cooperative Service System Based on a Production Process Ontology

Agricultural information cooperative services （AICS） are now becoming an important aspect of agriculture informatization. This study offers an ontological conception of the agricultural production process, establishing operational divisions corresponding to both the stages and the fundamental information requirements of the dairy industry production process in China, yielding a process ontology for the dairy industry as well as a business chain model. A framework for a dairy industry information cooperative service system was established, with service functions realized in a prototype system. The resulting agricultural process ontology built on the basis of biological characteristics has advantages as a classification standard for agricultural information; whereas the business chain model based on this agricultural process ontology allows for an effective distribution of agricultural information cooperative services. This study outlines a concept and demonstrates a prototype of a cooperative service capable of integrating diverse online agricultural information relevant to the dairy industry in China.

Library's industrial technology information service in science parks—Taking NSL's practice as an example

Purpose:The purpose of this paper is to explore how libraries can develop service and product strategies and the service support mechanism to provide industrial technology information service in science parks.Design/methodology/approach:The analysis is based on a case study of a large Chinese research library,National Science Library(NSL),the Chinese Academy of Sciences(CAS),in serving high-tech companies in Zhongguancun Science Park(Z-Park).Findings:NSL’s practices suggested that in serving business clients,libraries’ product and service strategies should be based on the understanding of users’ needs.Aside from those services that have been recognized by clients such as document retrieval & delivery and novelty search,libraries may expand their service and provide in-depth information analysis and consultation for some key clients.Moreover,a service and product development system should be established,which differentiates the libraries’ products and services from those of their competitors.In providing industrial technology information service,libraries need to construct the service support mechanism,publicize their service and learn to cooperate with clients to meet their demands for knowledge management and innovation.Research limitations:The generalizability of the findings is limited because they are based on an individual case study.Practical implications:Our service practices provide useful information for other libraries to expand their information service to high-tech companies in the new information environment.Originality/value:Z-Park is the first and one of the largest science and technology parks in China.Hence NSL’s practices in serving high-tech companies in Z-Park can be valuable to other libraries that intend to take up the similar service.
