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 19650-1:2018 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 significance 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 used in construction works through an asset life cycle, using the same data structure, terminology,
and globally unique identifiers to enable machine-readability. Data templates will be standardized and made
available across the built environment sector through data dictionaries based on EN ISO 12006-3.
The data template structure in this standard is based on the general data template structure in
prEN ISO 23387.
In Europe, various regulations and directives lay down harmonised rules for the marketing of products and
systems, and the CEN/CENELEC standards provide a common technical language to assess the performance
of products and systems for construction works. The common technical language should be the foundation
when creating a digital terminology for the European construction industry. The digital terminology should
be used in standardized structures, data templates, for describing construction products. The regulatory
nature of the common technical language requires that the digital terminology is compatible and does not
conflict with the regulatory declaration.
Building regulations, together with standards and specifications are intended to ensure that basic
requirements for construction works (Annex I of EU Regulation 305/2011 – Construction Products
Regulation) and other technical performances are met. Basic requirements for construction works and other
technical performances should be made digitally available and used as part of the 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 modeling (BIM).

4 Terminology variation between prEN ISO 23387 and CPR
In prEN ISO 23387, a general data structure has been introduced to define data templates for construction
objects. The terminology used in prEN ISO 23387 is aligned with terminology used in other BIM standards
developed in ISO/TC 59/SC 13 and CEN/TC 442.
The CPR lays down harmonised rules for the marketing of construction products in the EU. The Regulation
provides a common technical language to assess the performance of construction products.
Both terminology approaches differ in some parts. In order to define a specialized template for the area of
CPR, the variation of terminology is explained in Table 1.
The concept names from prEN ISO 23387 are reused in the UML in Figure 1 in this document, and
clarification is provided in Table 1, to make the terminology more understandable for use cases related to
the CPR.
The terminology from prEN ISO 23387 is used throughout this document where description of creation of
concepts is provided. For text related to the content in harmonised technical specifications, CPR related
terminology is used.
Table 1 provides a list with concept names from prEN ISO 23387, together with a clarification which is more
in line with the CPR terminology.

harmonised technical specifications.

Figure 1 — Data template UML diagram
For some concepts, self-relationships are provided. This mechanism allows for relating two concepts of the
same kind to each other. There are several use cases that require self-relationships, as described below in
subclauses 5.2 to 5.4. The following UML diagrams are extracts from Figure 1.
5.2 Data templates for construction products as kits
The self-relationship supports creation of data templates for kits. For this purpose, self-relations are
applicable for construction object concepts, representing construction products, and data template concepts.
UML representations of these relationships are provided in Figures 2 and 3.

5.3 Dependency relationships for properties
Two properties can be connected by a self-relationship. This mechanism supports a value for a single
property to be based on the value of another property. UML representation of this relationship is provided
in Figure 4.

5.4 Grouping properties in groups of properties
For the concept group of properties, a self-relationship is needed for the purpose of nesting properties with
different quantity kinds into the same group of property. UML representation of this relationship is provided
in Figure 5.
