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.

ISO 19131:2007(E)
Introduction
A data product specification is a detailed description of a dataset or dataset series together with additional
information that will enable it to be created, supplied to and used by another party. It is a precise technical
description of the data product in terms of the requirements that it will or may fulfil. However, the data product
specification only defines how the dataset should be. For various reasons, compromises may need to be
made in the implementation. The metadata associated with the product dataset should reflect how the product
dataset actually is.
A data product specification may be created and used on different occasions, by different parties and for
different reasons. It may, for example, be used for the original process of collecting data as well as for
products derived from already existing data. It may be created by producers to specify their product or by
users to state their requirements.
The purpose of this International Standard is to provide practical help in the creation of data product
specifications, in conformance with other existing standards for geographic information. An aim is to produce a
complete list of the items used to specify a data product.
This International Standard makes references to parts of existing standards. Some of the items used to
specify the data in a data product can also be used as metadata for a resulting dataset with the same data
product.
It is not necessary for a data product specification to specify the production process, but only the resulting
data product. Nevertheless, it may include production and maintenance aspects if judged necessary to
describe the data product.
This International Standard describes the content and structure of a data product specification. An example of
a data product specification is presented in Annex F.
When an item for a data product specification is already defined in another standard of the ISO 19100 series,
a reference to that document is explicitly made.
This International Standard is intended for use by producers, providers and potential users of data products.

5.3 UML model relationships
If an association is navigable in a particular direction, the model has a “role name” that is appropriate for the
role of the target object in relation to the source object. Thus, in a two-way association, two role names will be
supplied. Figure 2 represents how role names and cardinalities are expressed in UML diagrams.

NOTE Where cardinality is not explicitly stated in a diagram, it is assumed to be “exactly one”.

5.4 UML model stereotypes
A UML stereotype is an extension mechanism for existing UML concepts. It is a model element that is used to
classify (or mark) other UML elements so that they behave in some respect as if they were instances of new
virtual or pseudo metamodel classes whose form is based on existing base metamodel classes. Stereotypes
augment the classification mechanisms on the basis of the built-in UML metamodel class hierarchy. Below are
brief descriptions of the stereotypes used in this International Standard. For more detailed descriptions consult
ISO/TS 19103.
In this International Standard the following stereotype is used:
⎯ <> package that contains definitions, without any sub-packages.
5.5 Package abbreviations
Abbreviations are used to denote the package that contains a class. Those abbreviations precede class
names, connected by a “_”. The International Standard in which those classes are located is indicated in
parentheses. A list of those abbreviations follows.

6 General structure and content of a data product specification
A data product specification defines the requirements for a data product. It forms the basis for producing or
acquiring data. It may also help potential users to evaluate the data product to determine its fitness for use by
them. The information contained in a data product specification is different from that contained in metadata,
which provides information about a particular physical dataset. Information from the data product specification
may be used in the creation of metadata for a particular dataset that is created in conformance with that data
product specification. Thus, metadata describes how a dataset actually is, whilst a data product specification
describes how it should be. The requirements for metadata are described in ISO 19115. The relationship
between a data product specification and metadata is described more fully in Annex B.
A data product specification shall contain major sections covering the following aspects of the data product:
⎯ Overview — see Clause 7;
⎯ Specification scopes — see Clause 8;
⎯ Data product identification — see Clause 9;
⎯ Data content and structure — see Clause 10;
6 © ISO 2007 – All rights reserved

---------------------- Page: 18 ----------------------

SIST EN ISO 19131:2008
ISO 19131:2007(E)
⎯ Reference systems — see Clause 11;
⎯ Data quality — see Clause 12;
⎯ Data product delivery — see Clause 16;
⎯ Metadata — see Clause 18.
A data product specification may also contain sections covering the following aspects of the data product:
⎯ Data capture — see Clause 13;
⎯ Data maintenance — see Clause 14;
⎯ Portrayal — see Clause 15;
⎯ Additional information — see Clause 17.
Each of these sections of the data product specification is described in the following clauses. Each section,
except for the overview (see Clause 7), which is human-readable free text, corresponds to a UML package.
These packages are shown in Annex C.
The minimum description of a data product shall contain the mandatory elements within each section (see
UML model and corresponding tables in Annexes D and E).
7 Overview
The overview shall include the following parts:
⎯ information about the creation of the data product specification;
NOTE This may include the title, a reference date, the responsible party, the language and the topic category.
⎯ terms and definitions;
NOTE This may take the form of a reference to a terminology repository.
⎯ abbreviations;
⎯ the name and any acronyms of the data product;
⎯ an informal description of the data product.
The informal description of the data product shall contain general information about the data product which
may include the following aspects:
⎯ the content of the dataset;
⎯ the extent (both spatial and temporal) of the data;
⎯ the specific purpose for which the data shall be or has been collected;
⎯ the data sources and data production processes;
⎯ the maintenance of the data.
NOTE An informal description is intended to give a short introduction to the data product specification and allow a
human reader a better understanding of the specification.

ISO 19131:2007(E)
8 Specification scopes
The specification of a data product shall include a description of its scope, which may be restricted in terms of
spatial or temporal extent, feature types and properties included, spatial representation, or position within a
product hierarchy. The data product specification may specify a partitioning of the data content of the product
on the basis of one or more criteria. Such partitioning may be different for different parts of the data product
specification. Each such part of the data content shall be described by a specification scope that may inherit
or override the general specification scope.
Criteria that might be used as the basis for partitioning include, but are not limited to
⎯ spatial or temporal extent,
⎯ feature type,
⎯ property type,
⎯ property value,
⎯ spatial representation,
⎯ product hierarchy.
EXAMPLE Data products to support navigation often contain two sets of feature types: those that provide navigation
information that changes rapidly and is essential for safety of navigation, and those that provide background reference
information. Maintenance and delivery information would be partitioned on the basis of these groupings; reference system
information would not.
The information describing the specification scope shall include scope identification and items from the
following as required to describe the scope:
⎯ level — a code identifying the hierarchical level of the data;
⎯ level name — the name of the hierarchical level of the data;
⎯ level description — a detailed description of the level of the data;
⎯ extent — the spatial, vertical and temporal extent of the data;
⎯ coverage — the coverages to which the information applies.
A formal definition for specification scope information is given in Annex D which provides a UML model and
the corresponding data definitions. The specification scope shall be identified by a Scope ID in the statement
of that part of the specification.
9 Data product identification
The information identifying the data product shall include the following items:
⎯ title — the title of the data product;
⎯ abstract — a brief narrative summary of the content of the data product;
⎯ topic category — the main theme(s) of the data product;
⎯ geographic description — the extent of the geographic area covered by the data product.

SIST EN ISO 19131:2008
ISO 19131:2007(E)
The following optional items may be included where appropriate:
⎯ alternate title — short name or other name by which the data product is known;
⎯ purpose — summary of the intentions with which the data product is developed;
⎯ spatial representation type — the form of the spatial representation (e.g. vector data);
⎯ spatial resolution — a factor which provides a general understanding of the density of spatial data in the
data product;
⎯ supplemental information — any other descriptive information about the data product.
A formal definition for identification information is given in E.1 which provides a UML model and the
corresponding data definitions.
