Geographic information — General feature model and rules for application schema

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.

Information géographique — Modèle général des entités et règles relatives au schéma d'application

Le présent document définit le modèle général des entités (GFM) comme le métamodèle pour la création des schémas d'application dans le contexte de la modélisation de l'information géographique. Le GFM est expliqué et implémenté sous la forme de règles pour la création et la documentation de schémas d'application, y compris des principes de définition des entités. Le présent document est applicable: — la modélisation conceptuelle des entités et de leurs propriétés par rapport à un univers du discours; — la définition des schémas d'application; — les règles générales d'utilisation d'un langage de schéma conceptuel pour les schémas d'application; — des règles pour les schémas d'application utilisant UML comme langage de schéma conceptuel; — la transition entre les concepts du modèle conceptuel et les types de données du schéma d'application; — l'intégration de schémas normalisés provenant d'autres normes ISO d'information géographique dans le schéma de l'application. Le présent document ne s'applique pas: — au choix d'un langage de schéma conceptuel particulier pour les schémas d'application; — à la définition de schémas d'application particuliers quels qu'ils soient; — à la représentation des types d'entités et leurs propriétés dans un catalogue d'entités; — à la représentation des métadonnées; — aux règles de transposition d'un schéma d'application à un autre; — à l'implémentation du schéma d'application dans un environnement informatique; — au système informatique et à la conception du logiciel d'application; — à la programmation.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at

This third edition cancels and replaces the second edition (ISO 19109:2015), which has been technically
revised.
The main changes are as follows:
— — Changes in the title and scope
— — New sub-clauses discussing the concept of the General Feature Model
— — Re-organization of Clause 7Clause 7 to include only concepts of the General Feature Model and moving
the general rules for application schema to Clause 8Clause 8
— — Updating the references to other ISO/TC 211 standards in applicable cases to reflect classes in
respective latest versions
— — Removing the dependencies to other ICO/TC 211 standards related to attributes of features

Introduction
Any description of reality is always an abstraction, always partial, and always just one of many possible
“views”, depending on the application field.
The widespread application of computers and geographic information systems (GIS) has led to an increased
use of geographic data within multiple disciplines. With current technology as an enabler, society’s reliance
on such data is growing. Geographic datasets are increasingly being shared and exchanged. They are also used
for purposes other than those for which they were produced.
To ensure that data will be understood by both computer systems and users, it is necessary to fully document
the data structures for data access and exchange. The interfaces between systems, therefore, need to be
defined with respect to data and operations, using the methods standardized in this document. For the
construction of internal software and data storage within proprietary systems, any method is acceptable
provided it supports the standardized interfaces.
An application schema provides the formal description of the data structure and content required by one or
more applications. An application schema contains the descriptions of both geographic data and other related
data. A fundamental concept of geographic data is the feature.
This document aims to express the importance of continuing the modelling of geospatial information
according to the concepts contained in this document.

Geographic information — General feature model and rules for
application schema
1 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.
