This International Standard defines rules for creating and documenting application schemas, including principles for the definition of features.
The scope of this International Standard includes the following:
— conceptual modelling of features and their properties from a universe of discourse;
— definition of application schemas;
— use of the conceptual schema language for application schemas;
— 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.
