Introduction
Building information modelling (BIM) provides a digital process for describing and displaying
information required in the planning, design, construction and operation of constructed facilities. This
approach encompasses all aspects of the built environment, including civil infrastructure, utilities and
public space.
ISO 19650 (all parts) sets out the recommended concepts and principles for business processes across
the built environment sector in support of the management and production of information during the
life cycle of built assets when using building information modelling (BIM). To support the management
and production of information in these business processes, standardization is of the highest importance.
Machine-readable data is essential to provide a reliable and sustainable exchange of information in an
asset life cycle process.
Data templates provide a standardized data structure to describe the characteristics of construction
objects, enabling seamless information exchanges of construction industry business semantics through
the life cycle of any built asset.
Data templates should be standardized and made available across the built environment sector through
data dictionaries based on ISO 12006-3:2007.
Data templates should be used in conjunction with Industry Foundation Classes (IFC) in ISO 16739-1 to
enable and support open BIM processes.

3.1
component
named and individually scheduled physical item and feature that might require management, such as
inspection, maintenance, servicing or replacement, during the in-use phase
Note 1 to entry: Components can serve as interacting objects in a system (3.13).
[SOURCE: ISO 6707-1:2017, 3.4.1.4, modified — Note 1 to entry has been added.]
3.2
data dictionary
centralized repository of information about data such as meaning, relationships to other data, origin,
usage and format
Note 1 to entry: The definition is from IBM Dictionary of Computing.
[SOURCE: ISO 23386:2020, 3.9]
3.3
data template
data structure used to describe the characteristics of construction objects (3.4)
EXAMPLE 1 A data template provides a view based on an information exchange, e.g. a heating, ventilation and
air conditioning (HVAC) system designer is asking for the descriptions of the HVAC products that can be loaded
into the design system.
EXAMPLE 2 A data template provides manufacturers a standardized data structure that can be applied to any
internal system and/or process of handling product data, e.g. one or several product information management
systems can apply or map to this structure to enable machine readability, both internally and with any requests
from any software using the same data template structure. An HVAC product manufacturer can then answer the
request from any stakeholder including the HVAC system designer.
Note 1 to entry: The relevant scope of the data template can be used together with the term “data template”. E.g.
a data template for a product (3.9) can be named “product data template”. A data template for a system (3.13) can
be named “system data template”, etc.
Note 2 to entry: A data template can be used in an information exchange for a specific purpose for a construction
object in the inception, brief, design, production, operation and demolition of facilities.
3.4
construction object
object of interest in the context of a construction process
EXAMPLE 1 The construction object “wall” is a type of system (3.13).
EXAMPLE 2 The construction object “calcium silicate masonry unit” is a type of product (3.9).

Introduction
Building information modelling (BIM) provides a digital technology for describing and displaying
information required in the planning, design, construction and operation of constructed facilities.
Increasingly this modelling approach is expanding to encompass all aspects of the built
environment, including civil infrastructure, utilities and public space.
EN ISO 19650 sets out the recommended concepts and principles for business processes across
the built environment sector in support of the management and production of information during
the life cycle of built assets when using building information modelling (BIM). To support the
management and production of information in these business processes, the importance of
standardization is of the highest importance. Machine-readable data is essential to provide a
reliable and sustainable exchange of information in an asset life cycle process.
Data templates will enable construction project stakeholders to exchange information about
construction objects through an asset life cycle, using the same data structure, terminology, and
globally unique identifiers to enable machine-readability.
Data templates should be standardized and made available across the built environment sector
through data dictionaries based on EN ISO 12006-3, Building construction -- Organization of
information about construction works -- Part 3: Framework for object-oriented information.
Data templates should be used in conjunction with IFC, EN ISO 16739, Industry Foundation Classes
for data sharing in the construction and facility management industries, to enable and support open
BIM processes.
1 Scope
This International standard sets out the principles and structure for data templates for
construction objects. It is developed to support digital processes using machine-readable formats
using a standard data structure to exchange information about any type of construction object,
e.g. product, system, assembly, space, building etc, used in the inception, brief, design, production,
operation and demolition of facilities.
This standard provides the specification of a taxonomy model that defines concepts from EN ISO
12006-3, objects, collections, and relationships between them, to support the information need
for the specific purpose of the data template.
This standard provides the rules for linking between data templates and IFC classes within a data
dictionary based on EN ISO 12006-3.
This standard provides the rules for linking between data templates and classification systems
within a data dictionary based on ISO EN 12006-3.
It is not in the scope of this standard to provide the content of any data templates. The data
structure provided in this standard shall be used for developing specific data templates based on
standards developed in ISO/IEC, CEN/CENELEC, national standardization organizations, or other
sources describing information needs.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

3.1
component
product manufactured as a distinct unit to serve a specific function or functions

[ISO 6707-1:2016]

NOTE Components can serve as interacting objects in a system

3.2
data dictionary
database that contains metadata
[ISO 2382:2015]

3.3
data template
schema providing a standardized data structure used to describe the characteristics of
construction objects
NOTE 1 The relevant scope of the data template should be used together with the term
“data template”. E.g. a data template for a product should be named “product data template”. A
data template for a system should be named “system data template”, etc.

EXAMPLE 1 A data template can be used in an information exchange for a specific purpose for
a construction object in the inception, brief, design, production, operation and demolition of
facilities.
EXAMPLE 2: A data template provides a view based on an information exchange, e.g. an HVAC
system designer is asking for the descriptions of the HVAC products that can be loaded into the
design system.

EXAMPLE 3: A data template provides manufacturers a standardized data structure that can
be applied to any internal system and/or process of handling product data, e.g. one or several
product information management systems (PIM/PDM) can apply or map to this structure to
enable machine readability, both internally and with any requests from any software using the
same data template structure. An HVAC product manufacturer can then answer the request from
any stakeholder including the HVAC system designer.

3.4
construction object
object of interest in the context of a construction process
[ISO 12006-2:2015]
EXAMPLE 1 The construction object “wall” is a type of system
EXAMPLE 2 The construction object “calcium silicate masonry unit” is a type of product

3.5
enumerated value
concept type representing the description of a value of a property

3.6
globally unique identifier (GUID)
unique identifier generated using an algorithm
[ISO/IEC 11578:1996]

3.7
group of properties
group of properties enabling the properties to be organised

NOTE 1 There are multiple types of possible groups eg class, domain, reference
document, interdependent properties

NOTE 2 A property can be member of several groups of properties

3.8
Industry Foundation Classes (IFC)
specifies a conceptual data schema and an exchange file format for Building Information Model
(BIM) data
[ISO 16739:2013]

3.9
product
object manufactured or processed

[ISO 6707-1:2016]

3.10
property
feature or quality of an object

[ISO/DIS 1087]

NOTE When a property is named together with reference to a technical specification,
where the instructions to assess the performance are available (usually standards), it is to be
regarded as a specific property. The relationship between property and specific property is
modelled as a parent child relationship.
EXAMPLE 1 length, sound reduction index (properties)

EXAMPLE 2 Length according to EN 12058, sound reduction index according to EN ISO
10140-4 (specific properties)


3.11
quantity
property of a phenomenon, body, or substance, where the property has a magnitude that can be
expressed by means of a number and a reference

[EN ISO 80000-1:2013]

NOTE Quantities can appear as base quantities or derived quantities

EXAMPLE 1 Length, mass, electric current (ISQ base quantities)

EXAMPLE 2 Plane angle, force, power (derived quantities)


3.12
reference document
publication that is consulted to find specific information, particularly in a technical or scientific
domain. A reference document can be associated with any data present in a data dictionary. It
can include document date and version

EXAMPLE EN 771-1:2011+A1:2015 Specification for masonry units, Part 1: Clay masonry
units

3.13
system
interacting objects organized to achieve one or more stated purpose

UML
Unified Modelling Language. Language to provide system architects, software engineers, and
software developers with tools for analysis, design, and implementation of software-based
systems as well as for modeling business and similar processes.
[ISO/IEC 19505]

3.15
unit
unit of measurement
measurement unit
real scalar quantity, defined and adopted by convention, with which any other quantity of the
same kind can be compared to express the ratio of the second quantity to the first one as a
number

NOTE Units can appear as base units or derived units

EXAMPLE 1 Metre, kilogram, ampere (SI base units)

EXAMPLE 2 Radian, newton, watt (derived units)

4 General structure of data templates
This clause describes the general structure of a data template, and how it is modelled in UML
based on ISO/IEC 19505 Information technology -- Object Management Group Unified Modeling
Language (OMG UML). The concepts used in the UML diagram are in accordance with EN ISO
12006-3, while in this standard some of the concept names have been modified to better fit with
market terminology. Table 1 provides the link between the terminology in EN ISO 2338
