Adopts ISO 19128:2005 which provides systems users and designers with the specifics of the behaviour of a service that produces spatially referenced maps dynamically from geographic information. It specifies operations to retrieve a description of the maps offered by a server, to retrieve a map, and to query a server about features displayed on a map.
