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.

ISO 23386:2020(E)
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.
INTERNATIONAL STANDARD ISO 23386:2020(E)
Building information modelling and other digital
processes used in construction — Methodology to describe,
author and maintain properties in interconnected data
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.

4 Rules to define properties and groups of properties
4.1 General
To be non-ambiguous, machine-readable as well as human-understandable, properties and groups
of properties shall be defined by a set of attributes. Some attributes are mandatory, and others are
optional.
For a property to be human-understandable, any application following this document may be able to
display the value of many attributes defining this property, for example name, name of the reference
document, test method, unit, etc.
4.2 Property
A property shall be defined using the set of attributes as listed in Table 1.
ISO 23386:2020(E)
4.3 Group of properties
A group of properties shall be defined using the set of attributes as listed in Table 2.
Applicants can propose a group of properties as appropriate for their needs.
The different categories of a group of properties are (exhaustive list):
— alternative use;
— class;
— composed property;
— domain;
— reference document.
Groups 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: Panel (class corresponding to a family of products in a classification);
— class: ifcWall;
— domain: Acoustic (domain corresponding to a scientific discipline), architecture, economy;
— composed property: “concrete facing quality” is a group of properties linking 3 properties (concrete
planarity, concrete hue, concrete texture).
4.4 Attributes list
4.4.1 Attributes of a property
Table 1 provides an exhaustive list of attributes used to manage a property within a data dictionary.
Table 1 contains 8 columns:
— Code: code that can be used to identify the attribute;
— Name: name of the attribute;
— Description: description of the attribute, and how it shall be used;
— Example: some examples of possible values for the attribute;
— Interconnected data dictionaries management rule: rule that defines if it is mandatory or not to
provide a value for the attribute. When “calculated” is noticed, this means that the value of the
attribute is provided by the system managing a data dictionary, not by a user (i.e. when a request
has been validated, the system shall change the property’s attribute “status” to “active”);
— Request form management rule: rule that defines if it is mandatory or not relevant to provide a
value for the attribute in a request form to interact with the data dictionary;
— Type: datatype of the attribute;
— List of values: list of possible values for the attribute.
