Study on WPS Implement Framework with Shark Workflow

WPS (web processing service) is the specifications launched by OGC organizations for dealing with space data, which is different from the conventional Web Service. There aren´t dedicated workflow environment for WPS service framework, and support of workflow environments in WPS application is the key technical challenges. Some of the workflow environment, such as Shark, still lack of effective implementation of the framework. This paper analyzes the application framework model of WPS service in BEPL workflow environment, proposed WPS implementation framework in the Shark workflow environment, WPS service implementation prototype is established based on Shark 2.0, which is verified by typical test.
