This paper presents a geographically distributed mobile teamwork management system that combines the simplicity of Web services architecture and protocols, with the GPS-based location information retrieval, and a geographical mapping application. The aim of our work is to offer a Web-based client-server system heading towards a better management of mobile teamwork departments (such as operating and maintenance departments of telecommunications companies) in the idea of making more efficient use of overall resources.

We have designed a novel server-side data validation service, based upon semantic web technologies to solve the lack of data validation and bypassing validation issues. The NDVS consists of five components: RDFa annotation for elements of web pages, interceptor, RDFa extractor, RDF parser, and data validator. Our solution is implemented as a prototype. In this paper, we have conducted a pilot study to prevent the security vulnerabilities at the application level such as SQL injections. The results of this initial study have shown that the proposed service (NDVS) could provide a high coverage of prevention of security vulnerabilities. [ABSTRACT FROM AUTHOR]
