Workflow Enactment of Grid-Enabled Geospatial Web Services

The Open Geospatial Consortium (OGC) has developed a series of specifications for geospatial web services. In parallel, the grid community has developed the Open Grid Services Architecture (OGSA) to facilitate the development of web services on the Grid. The orchestration of OGC and OGSA web services in workflows is currently limited by a lack of interoperability between these two architectures. This paper discusses the differences in OGC and OGSA web services and proposes an approach for orchestrating these web services in workflows based on the Business Process Execution Language (BPEL).
