Reusable eScience Software StackOpen Grid Computing Environments project led by Indiana University adopts software components from domain specific Science Gateways and generalizes/hardens/tests and releases them to the gateway community at large. E-Science Community has adopted Axis2 as the default Web Service Framework.With the inspiration and experience with axis2, OGCE project is pursuing to submit a ASF incubator proposal to collaborate, develop and maintain Scientific workflow tool suite.
