- 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;
