Definition and Implementation of an Active Web Map Service

The most widespread Open Geospatial Consortium (OGC) specification for GIS defines the interface of a Web Map Service (WMS). A service implementing this interface accepts an HTTP request from a client and replies with a map encoded in either a raster format or a vector format such as SVG (Scalable Vector Graphics). However, in both cases, the response of the WMS represents a static map that cannot react to user actions. It would be useful to obtain vector maps encoded in active SVG that can execute actions and change their visual appearance in response to user-triggered events.
