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

The main changes are as follows:
— XML encoding has been added;
— mandatory sections working as place holders have been introduced;
— the UML model has been restructured, introducing new/renamed attributes and elements, and
ISO 19115-1 datatypes have been used where possible;
— new attributes and elements have been introduced to separate information in the overview (6.2.7.2).
— in subclause 6.2.7, "Class IdentificationSection,":
— the description and identification of the data product has been clearly separated from the
description and identification of the specification,
— the data type for attribute purpose has been changed to allow explanation of the purpose of the
data product using use cases,
— the attribute extent has been changed to allow specification of temporal and vertical extent, in
addition to the geographical extent, and
v
ISO 19131:2022(E)
— a new attribute restriction has been introduced, used to describe handling restrictions of the
data product;
— in the Scope:
— relations between scopes have been removed (the concept of super- and sub-scopes), and
— a provision has been introduced requiring that at least one of the attributes level, levelName, or
extent be used for each scope;
— the Data content and structure section (6.5) has been restructured using elements from ISO 19115-1;
— in the Reference systems section (6.6), the data type of the attribute temporalReferenceSystem has
been changed;

requirement in other contexts;

to contain information previously located in the attribute dataCaptureStatement;
— in the Maintenance section (6.9), information about maintenance has been made mandatory, and

mandatory attribute introduced;
— in the Delivery section (6.11), a new attribute deliveryService has been introduced;

Introduction
A data product specification is a specification of a dataset or dataset series together with additional
information that will enable it to be created, supplied to and used by another party. In this context of
creating, supplying and using data products, the specification thereof is of essence in a controlled and
standardized process leading to interoperability. The data product specification is the final product
in a process that describes the conceptual formalization of semantics and data structure related to
specific requirements or use cases. It is a precise and full description of the data product in terms of the
requirements that it will or may fulfil. A data product specification is primarily a technical document
that may contain non-technical elements such as narrative descriptions of some aspects, like the
overview or data capture statements. However, for various reasons compromises can need to be made
in the implementation.
The purpose of this document is to provide requirements on the content of data product specifications,
in conformance with other existing International Standards for geographic information. This
conformance is at different levels. Firstly, there is the aspect of a dataset and its metadata conforming
to a data product specification, and secondly that the data product specification conforms to this
document. Some of the items used to specify the data product in a data product specification can also
be used as metadata for a data product that conforms to the data product specification. Figure 1 shows
how a data product specification relates to datasets and their metadata.
Figure 1 — Relations between this document (ISO 19131), the data product specification and
the datasets
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
vii
ISO 19131:2022(E)
for products derived from already existing data. It may be created by producers to specify their product
or by users to state their requirements.
This document describes the content, structure and encoding of a data product specification.
This document contains URIs for normative statements, conformance classes,
conformance tests and requirements classes. Other International Standards are
also referenced with URIs. URIs to normative statements within this document are
a combination of the namespace https://standards.isotc211.org/19131/-/2 and the
local identifier. The description of elements in the local identifiers can be found at

6 Requirements for data product specifications
6.1 General
Subclauses 6.2 to 6.13 describe elements of a data product specification based on the conceptual UML
model for ISO 19131 (second edition) being part of the ISO/TC 211 harmonized model. Furthermore,
additional descriptions, requirements and recommendations are included. A compact documentation of
the elements in the UML model is provided in Annex C.
Annex D contains an example of a data product specification's content according to the content in 6.2 to
6.13.
Subclause 6.14 provides a recommendation on how to order the elements described in 6.2 to 6.13 when
human readability is prioritized.
The rules that apply for the content of a data product specification comprise a requirements class
summarized in Table 4.
ISO 19131:2022(E)
