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.

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
