GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. Note that the concept of feature in GML is a very general one and includes not only conventional vector or discrete objects, but also coverages (see also GMLJP2) and sensor data.

The ability to integrate all forms of geographic information is key to the utility of GML. GML contains a rich set of primitives which are used to build application specific schemas or application languages. These primitives include: The original GML model was based on the World Wide Web Consortiums Resource Description Framework (RDF).

Subsequently, the OGC introduced XML schemas into GMLs structure to help connect the various existing geographic databases, whose relational structure XML schemas more easily define. The resulting XML-schema-based GML retains many features of RDF, including the idea of child elements as properties of the parent object (RDFS) a...
