  • 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;
