Geographic information - Feature concept dictionaries and registers (ISO 19126:2009)

This International Standard will specify schemas for feature concept dictionaries and for the establishment and management of feature concept dictionaries as registers. This International Standard will not specify schemas for feature catalogues or for the management of feature catalogues as registers. However, because feature catalogues are often derived from feature concept dictionaries, this International Standard does specify a schema for a hierarchical register of feature concept dictionaries and feature catalogues. These registers are in accordance with ISO 19135 Geographic information - Procedures for registration of items of geographic information.

Geoinformation - Verzeichnisse und Register für Featurekontepte (ISO 19126:2009)

Diese Internationale Norm legt ein Schema für Featurekonzeptverzeichnisse fest, die als Register eingerichtet und verwaltet werden. Sie legt keine Schemata für Objektartenkataloge oder für die Verwaltung von Objekt¬artenkatalogen als Register fest. Da Objektartenkataloge jedoch häufig von Featurekonzeptverzeichnissen abgeleitet sind, wird in dieser Internationalen Norm eine Schema für ein hierarchisches Register von Feature¬konzeptverzeichnissen und Objektartenkatalogen festgelegt. Diese Register entsprechen ISO 19135.

Information géographique - Dictionnaires de concepts de caractéristiques et registres (ISO 19126:2009)

L'ISO 19126:2009 spécifie un schéma pour les dictionnaires de concepts de caractéristiques à établir et à gérer comme des registres. Elle ne spécifie pas de schémas pour les catalogues de caractéristiques ou pour leur gestion comme des registres. Toutefois, compte tenu que les catalogues de caractéristiques sont souvent dérivés des dictionnaires de concepts de caractéristiques, l'ISO 19126:2009 ne spécifie pas un schéma pour un registre hiérarchique de dictionnaires de concepts de caractéristiques et de catalogues de caractéristiques. Ces registres sont conformes à l'ISO 19135.

Geografske informacije - Slovarji in registri konceptov o pojavih (ISO 19126:2009)

Ta mednarodni standard opredeljuje shemo za slovarje konceptov o pojavih, ki bodo vzpostavljeni in upravljani kot registri. Ne opredeljuje shem za kataloge pojavov ali za upravljanje katalogov pojavov kot registrov. Vendar ker katalogi pojavov pogosto izhajajo iz slovarjev konceptov o pojavih, ta mednarodni standard vseeno opredeljuje shemo za hierarhično organiziran register slovarjev konceptov o pojavih in katalogov o pojavih. Ti registri so v skladu z ISO 19135.

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction

This International Standard specifies a schema for geographic feature concept dictionaries managed as

registers. As described in ISO 19101, geographic features are abstractions of real world phenomena

associated with a location relative to the surface of the earth, about which data are collected, maintained and

disseminated.

A feature concept dictionary provides basic definitions and related information about a set of concepts that

may be used to describe geographic features and shared across multiple application areas. Elements from a

feature concept dictionary may be reused in one or more feature catalogues. A feature catalogue is often

associated with a particular application schema, product specification and data set. It provides a complete

textual specification of a set of feature types and their properties and relationships. See Annex A for further

discussion of the relationships between feature concept dictionaries, feature catalogues, application schemas

and product specifications.

ISO 19135 specifies procedures for the registration of items of geographic information. Items of geographic

information that may be registered are members of object classes specified in technical standards such as

those developed by ISO/TC 211. This International Standard defines object classes and specifies rules used

to establish and maintain feature concept dictionaries as ISO 19135 conformant register schemas.

ISO 19135 specifies the structure of a hierarchical register in which the principal register holds a set of items

that describe the subregisters. This International Standard specifies a schema for a hierarchical register where

the subregisters are feature concept dictionaries and/or feature catalogues. This International Standard

specifies an accompanying schema. The resulting hierarchical register may be used as a basis for

harmonization and the establishment of interoperability between different geographic information communities.

Feature concept dictionaries and feature catalogues maintained as registers may serve as sources of

reference for similar registers established by other geographic information communities as part of a system of

cross-referencing. Cross-referencing between respective items in registers of items of geographic information

may be difficult in cases where the structure of registers differs between information communities. This

International Standard may serve as a guide for different information communities to develop compatible

registers that can support a system of geographic information cross-referencing.

The Digital Geographic Information Working Group (DGIWG) community feature concept dictionary and

register is described as an example implementation of this International Standard.

INTERNATIONAL STANDARD ISO 19126:2009(E)
Geographic information — Feature concept dictionaries and
registers
1 Scope

This International Standard specifies a schema for feature concept dictionaries to be established and

managed as registers. It does not specify schemas for feature catalogues or for the management of feature

catalogues as registers. However, because feature catalogue are often derived from feature concept

dictionaries, this International Standard does specify a schema for a hierarchical register of feature concept

dictionaries and feature catalogues. These registers are in accordance with ISO 19135.

2 Conformance
2.1 Introduction

To conform to this International Standard, all of the conditions specified for at least one of the two

conformance classes described below shall be satisfied.
2.2 Conformance for a feature concept dictionary

Any feature concept dictionary that claims conformance to this International Standard shall satisfy all of the

conditions specified in the following abstract test suites:
a) ISO 19135, A.1, for general conformance to ISO 19135, and
b) B.2 of this International Standard.

A feature concept dictionary register established by ISO/TC 211 shall in addition satisfy all of the conditions

specified in the ISO 19135 abstract test suite for registers established by ISO/TC 211 (ISO 19135, A.3).

2.3 Conformance for a register of feature concept dictionaries and/or feature catalogues

Any register of feature concept dictionaries and/or feature catalogues that claims conformance to this

International Standard shall satisfy all of the conditions specified in the following abstract test suites:

a) ISO 19135, A.1, for general conformance to ISO 19135,
b) ISO 19135, A.2 for conformance to ISO 19135 as a hierarchical register, and
c) B.3 of this International Standard.

A register of feature concept dictionaries and/or feature catalogues established by ISO/TC 211 shall in

addition satisfy all of the conditions specified in the ISO 19135 abstract test suite for registers established by

ISO/TC 211 (ISO 19135, A.3).

concept that may be specified in detail as one or more feature association types

EXAMPLE A “supports” feature association concept describes a relationship between real world phenomena such

as “highways” and “bridges” where the role of one feature is that it is supported-by the other feature (whose role is

supporter-of).
4.1.8
feature attribute
characteristic of a feature
[ISO 19101:2002, definition 4.12]

EXAMPLE 1 A feature attribute named “colour” may have an attribute value “green” which belongs to the data type

“text”.

EXAMPLE 2 A feature attribute named “length” may have an attribute value “82,4” which belongs to the data type

“real”.

NOTE 1 A feature attribute may occur as a type or an instance. In this International Standard, feature attribute type is

[ISO 19135:2005, definition 4.1.6]

NOTE 1 Class is used in this context to refer to a set of instances, not the concept abstracted from that set of instances.

NOTE 2 To avoid potential ambiguity in this International Standard, the expression “register item class” is used.

4.1.18
nominal value

5.1 Introduction

A feature concept dictionary describes concepts that may be used to characterize real world phenomena.

Feature types and feature property types may then be specified using these concepts and documented in a

feature catalogue. This International Standard specifies a feature concept dictionary schema (5.2 and

Clause 6).

ISO 19135 specifies procedures to be followed in preparing and maintaining registers of items of geographic

information. Such registers may be used to support discovery of, access to, and use of the contents of feature

concept dictionaries and feature catalogues. This International Standard specifies a schema for feature

concept dictionaries as registers and information to be included i
