Scope

This document defines the General Feature Model (GFM) as the metamodel for creating application schemas in the context of geo-information modelling. The GFM is explained and implemented as rules for creating and documenting application schemas, including principles for the definition of features.

This document is applicable to:

— conceptual modelling of features and their properties from a universe of discourse;
— definition of application schemas;
— general rules for using a conceptual schema language for application schemas;
— rules for application schemas using UML as the conceptual schema language;
— transition from the concepts in the conceptual model to the data types in the application schema;
— integration of standardized schemas from other ISO geographic information standards with the application schema.

This document does not apply to:

— choice of one particular conceptual schema language for application schemas;
— definition of any particular application schemas;
— representation of feature types and their properties in a feature catalogue;
— representation of metadata;
— rules for mapping one application schema to another;
— implementation of the application schema in a computer environment;
— computer system and application software design;
— programming.
