GML-GeoRSS GML From http://georss.org/gml

Geography Markup Language (gml) is an XML grammar written in XML Schema for the modelling, transport, and storage of geographic information...GML provides a variety of kinds of objects for describing geography including features, coordinate reference systems, geometry, topology, time, units of measure and generalized values. A geographic feature is "an abstraction of a real world phenomenon; it is a geographic feature if it is associated with a location relative to the Earth?. So a digital representation of the real world can be thought of as a set of features.
