Web Application FrameworkWeb services are modular components that gain value when connected to form a chain of services, thereby creating a web application. The services can be geographically distributed among servers. The services come together by way of a workflow, which constructs and manages a set of services chained together.
*The WMS request from the web application is extended to include non-standard WMS elements that control the service flow.
