Web services provide a web-based solution to achieve the interoperability of geospatial information processing — meanwhile specialized users such as hydrological scientists require more advanced services for analyzing and processing huge volumes of data. River channel storage volume calculation is one of important hydrological processes for decision of anti-flood. This paper presents a web processing...
A reputation service is an essential part of a reputation system, which collects, distributes, and aggregates feedback about service providers' past behaviour. The feedback, as a score, is given interactively or by a user or is derived from a monitoring process automatically. The reputation service accommodates for each service provider an accumulated score as its reputation, which is produced by...
The method for applying web service technology to implement invocation of product design resources based on the inheritance mechanism of remote component class is introduced, the detailed account of operating process is given, a prototype system is developed, and the speed reducer is illustrated to validate the proposed method.
Web feature service is an important part of geospatial data interoperability and enables GIS data with different formats to be operated at feature-level. Open Geospatial Consortium (OGC) has already developed standard implementation specifications for Web feature service, and for those Web feature services with different versions, such as WFS1.1, WFS1.0. OGC also define different schemas. Different...
Web services over the Internet are widely used nowadays. The problem of secure access to Web-based systems is of great importance naturally. Compared with the existing models, the action-based access control (ABAC) model is the most suitable to control the access on Web services. In this paper, the ABAC model is introduced. Then, the security architecture of ABAC for Web services is proposed. In the...
FEA is a key product development tool, and remote FEA (finite element analysis) services via internet are an effective and economical way to popularizing FEA technology for different-sized manufacturing enterprises. For FEA grid portal, modeling technologies of FEA grid services and grid information management structure are presented in this paper. For modeling technologies of FEA grid service, workflow...
An ideal engineering computational environment for solving design problems should be flexible, which is characterized by helping designers to establish solution strategy conveniently and integrating design resources effectively. In this paper, a flexible engineering computational system called engineering computational service grid (ECSG) based on grid portal technology and workflow technology is...
