This paper describes an approach to generate GI standards such as OpenGIS Geography Markup Language (GML) and ISO 19118 XML Encoding from UML. GML application schemas in OpenGIS context are being developed by using XML Schema directly and without any relation to UML models. It is SINTEFs belief that a model-driven architecture using UML is more suitable for specifying GML application schemas. SINTEF has used a model-driven architecture for several years and has also been strongly involved in defining the ISO GI standards. The model-driven architecture is investigated further by SINTEF in the project GeNorway - Model-based infrastructure for living geospatial data in eNorway. GeNorway shall implement a Norwegian version of an OGC-conform Web Mapping test case built on top of the Norwegian Spatial Data Infrastructure (NGIS).
