OWS2GRID: A Prototype and Building System of WSRF-Enabled OGC Web Service

摘要

In this paper, key methods and prototype that integrate OGC Web Service (OWS) into grid environment is analysed and we describe a resource-oriented architectural approach. The concrete is a progress in which a model extracting stateful resource under WSRF (Web Service Resource Framework) is provided. This paper presents OWS2GRID, a framework that extends the Introduce Toolkit [1] for supporting OGC web service on Grid environments. The OWS2GRID framework adopts the WSRF specification for creating grid service resource and publishing them to distributed grid nodes. The OWS2GRID user interface is a modified template factory that converts stateless OGC WS to stateful wsrf-enabled service. The paper describes the design and the implementation of OWS2GRID using a release of the WSRF library. To evaluate the efficiency of the proposed system, a result of wrapped OWS in Globus indicate better performance and collaborative than standard OWS through a visual component in OWS2GRID.
