A Workflow Service Scenario Based on uWDL for Smart Agriculture

A workflow can weave independent jobs into a chain of work processes, based on a scenario. The uWDL is an XML-based workflow language that can supply web services to users with various contexts that can be dynamically occurring in real world. With the uWDL, users can easily make context-aware workflow services in the various computing environments. In this paper we design and develop a workflow scenario in uWDL to support context-aware services in the area of the agricultural environment that tends to be unsystematically and dynamically changed. The developed scenario will show that the context-aware workflow technology based on uWDL can be one of the reasonable and potential solutions for the service automation in the smart agriculture. For this, we use contexts, which are based on an ontology specified in agricultural domains, as service execution conditions to provide context-aware services. And, we will show how to define various environmental data in agriculture as context information through uWDL. Therefore, with the uWDL-based workflow scenario for smart agriculture, a developer can easily make smart agricultural application services such as a growth monitoring service, a shipment control service, and an automatic cultivation service.
