The Open Grid Services Architecture (OGSA) provides a high-level framework for service-oriented grid architecture, mostly based on web service standards. The vision of a worldwide computing grid evokes the scenario of electronic markets for grid services. The object of our investigation is a service-oriented grid architecture model that is compliant with(More)
Implementing and using Grids requires a suitable Grid middleware. A reference model for the architecture of Grid middleware is the Open Grid Service Architecture (OGSA) which proposes a service-oriented architecture based on Web service technologies. As a consequence, the potential of such OGSA compliant Grid middleware is limited by the capabilities of Web(More)
