Introduction
In the digital built environment, there will not be a single data dictionary which comprises all the
definitions which are needed in all BIM domains. Different groups, possibly in different countries, will
create or have created separate data dictionaries, specialized for their needs, based on the legislation
and culture. We are, and will be faced with, various separated data dictionaries. They may even reside
on the same platform yet logically they are detached.
For the future of BIM, it is important to ensure that these data dictionaries can be interoperable in tools
and applications.
— The elements of the data dictionaries need to be described by the same attributes. If this is agreed
and done by all data dictionary providers, it becomes possible to map properties in one data
dictionary to properties in other data dictionaries. This can lead to reuse of properties and to the
harmonization of properties across data dictionaries. In addition, this is an important step to allow
BIM applications to use multiple data dictionaries consistently.
— The governance of the data dictionaries needs to follow the same rules with respect to the building
and development of the data dictionaries’ content.
The assumption is that the data dictionaries are independent from each other, they are connected in
a coordinated network of data dictionaries (again, there may exist several of these networks). Within
the network, the data dictionaries are related, which is visible, for instance, using a specific attribute
which maps properties and groups of properties of different data dictionaries to each other. Any data
dictionary in the network of coordinated data dictionaries is independent, i.e. it has its own processes
and committees to control the development and evolution of the data dictionary; meanwhile, they all
follow the same description and governance rules described in this document.
This document specifies the attributes to define properties and groups of properties of a single data
dictionary as well as the processes and commissions/roles for the governance of a single data dictionary
in a network of coordinated data dictionaries. In the governance processes, it is described how the
single data dictionary deals with queries and change requests and the extension of queries to other
connected data dictionaries; information of other connected data dictionaries regarding change is an
integral part of this process.
This document contributes to ensuring the quality and the unicity of property descriptions and avoiding
the creation of duplicates.

Building information modelling and other digital
processes used in construction — Methodology to describe,

dictionaries
1 Scope
This document establishes the rules for defining properties used in construction and a methodology
for authoring and maintaining them, for a confident and seamless digital share among stakeholders
following a BIM process.
Regarding the definition of properties and groups of properties, this document provides:
— definitions of properties and groups of properties as a list of attributes;
— definitions of all the provided attributes.
Regarding the authoring and maintaining process, this document provides:
— definitions and roles of applicants;
— definitions and roles of experts and the commission of experts;
— definitions of request’s attributes;
— definitions of expert’s attributes;
— requirements to establish the management rules to interconnect data dictionaries through the
mapping process for properties and groups of properties.
To apply the methodology of this document, it is presupposed that the following are in place:
— an established governance model for a data dictionary;
— a framework for a network of data dictionaries.
It is not in the scope of this document to provide the content of the interconnected data dictionaries.

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.

Introduction
In the digital built environment there will not be a single dictionary which comprises of all the
definitions which are needed in all BIM domains. Different groups, possibly in different countries, will
and have defined separate dictionaries, specialized for their needs, for their legislation, maybe for their
culture. We are and will be faced with various separated dictionaries. They may even reside on the
same platform, logically they are detached.
For the future of BIM it is important to ensure that these dictionaries can be interoperable in tools and
applications.
— The elements of the dictionaries, for instance, the properties, need to be described by the same
attributes. If this is agreed and done by all dictionary providers, then it is quite simple to map
properties in one dictionary to properties in other dictionaries which can lead to reuse of properties
and to harmonization of properties across dictionaries. In addition, this is an important step to
allow BIM applications to use a set of dictionaries in a common way.
— The governance of the dictionaries has to follow the same rules with respect to the building and
development of the dictionaries’ content.
The assumption is that the dictionaries are independent from each other, but that they are connected
in a coordinated network of dictionaries (again, there may exist several of these networks). Within the
network, the dictionaries are related, which is visible, for instance, by the use of a specific attribute
which maps properties and groups of properties of different dictionaries to each other. Any dictionary
in the network of coordinated dictionaries is independent, i.e. it has its own processes and committees
to control the development and evolution of the dictionary, they all follow the same description and
governance rules defined in this standard.
This standard defines the attributes to define properties and group of properties of the single
dictionaries as well as the processes and committees / roles for the governance of the single dictionary
in a network of coordinated dictionaries. In the governance processes, it is described how the single
dictionary deals with queries and change requests, and the extension of queries to other connected
dictionaries, information of other connected dictionaries regarding change is an integral part of this
process.
This document contributes to ensure the quality and the unicity of properties descriptions by managing
the duplicates issue.
For a property to be human understandable, any application following this standard should be able to
display the value of many attributes defining this property, for example name, name of the reference
document, test method, unit…

The different categories of group of properties are:
— class
— domain
— reference document
— interdependent properties
— specific use
Group of properties can be organised in tree structures. Any property attached to a group of properties
is inherited by the sub-group(s) of properties.
Any property may be included in several groups of properties.
EXAMPLE
— class: Plasterboard (class corresponding to a family of products in a classification);
— domain: Thermal (domain corresponding to a scientific discipline);
— EN 13162 (designation that corresponds to a harmonised standard and in fact makes reference to the
properties listed in Annex ZA of the standard, CE marking medium);
— interdependent properties: “concrete facing quality” is a group of properties linking 3 properties (concrete
planarity, concrete hue, concrete texture);
— specific use: where a part of industry as agreed on a group of properties which is not defined in a specific source.
4.4 Attributes list
4.4.1 Attributes of property
The attributes of a property are defined in Table 1.
4.4.2 Attributes of group of properties
The attributes of a group of properties are defined in Table 2.
