Description of BS EN ISO 19109:2025 - TC 2025

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.
