Building Information Modelling (BIM) - Semantic Modelling and Linking (SML), Part 2: Domain-specific modelling patterns

This document (part 2) provides extended standard semantic modelling patterns for (at least) the following domain-specific asset aspects:
-   support for distinction between two subtypes of physical objects: spatial regions and real ("tangible") objects; the latter being discrete or continuous ("bulk matter");
-   support for the materialization of physical objects, adding generic chemistry aspects directly relevant for the built environment dealing with materials like concrete, steel, wood and asphalt;
-   support for the interaction between objects including connections, interfaces and ports. Interactions being defined as activities where material, information, energy or forces are transferred;
-   support for the definition of unstructured, human-interpretable, requirements, coming from appointing party needs, laws and regulations or sector recommendations;
-   support for implicit groups having no explicit members (to model situations like "all main girders of some steel bridge");
-   support for the explicit modelling of measurements reusing the existing W3C SOSA ontology (as a lightweight but self-contained SSN core ontology);
-   support for spatial geometry (location/shape) reusing OGC GeoSPARQL (GML/WKT) and the WGS84_pos ontology (GPS).

Bauwerksinformationsmodellierung (BIM) - Semantische Modellierung und Verknüpfung (SML) - Teil 2: Domänenspezifische Modellierungsmuster

Dieser Teil2 stellt erweiterte semantische Modellierungsmuster für (mindestens) die folgenden domänenspe
zifischen Asset-Aspekte bereit:
—
Unterstützung der Unterscheidung zwischen zwei Subtypen von physischen Objekten: räumliche Regionen und reale („greifbare“) Objekte; letztere können diskret oder dauerhaft sein („Masse“);
—
Unterstützung bei der Materialisierung von physischen Objekten durch Hinzufügen von generischen che
mischen Aspekten, die für die gebaute Umwelt direkt relevant sind und Materialien wie Beton, Stahl, Holz und Asphalt betreffen;
—
Unterstützung für die Interaktion zwischen Objekten, einschließlich Verbindungen, Schnittstellen und Anschlüssen. Interaktionen werden als Aktivitäten definiert, bei denen Material, Informationen, Energie oder Kräfte übertragen werden;
—
Unterstützung bei der Definition unstrukturierter, von Menschen interpretierbarer Anforderungen, die sich aus den Bedürfnissen der Informationsbesteller, Gesetzen und Vorschriften oder Branchenempfeh
lungen ergeben;
—
Unterstützung für implizite Gruppen, die keine expliziten Mitglieder haben (zur Modellierung von Situa
tionen wie „alle Hauptträger einer Stahlbrücke“);
—
Unterstützung für die explizite Modellierung von Messungen unter Wiederverwendung der bestehenden W3C-SOSA-Ontologie (als einfache, aber in sich geschlossene SSN-Kern-Ontologie).
—
Unterstützung für räumliche Geometrie (Ort/Form) unter Wiederverwendung von OGCGeoSPARQL (GML/WKT) und der Ontologie WGS84_pos (GPS).
Diese Modellierungsmuster (unten fett gedruckt dargestellt) können alle in den globalen Modellierungsrah
men eingeordnet werden, der in Form einer Taxonomie von Teil1 bereitgestellt wird. Diese Blattkonzepte

Modélisation d'informations de la construction (BIM) - Modélisation et liaisons sémantiques (SML) - Partie 2 : Patrons de modélisation spécifiques à un domaine

Le présent document (la partie 2) fournit les patrons de modélisation sémantique de base étendus pour (au moins) les aspects suivants des actifs spécifiques à un domaine :
—   prise en charge de la distinction entre deux sous-types d'objets physiques : régions spatiales et objets réels (« tangibles ») ; ces derniers étant discrets ou continus (« matière en vrac ») ;
—   prise en charge de la matérialisation des objets physiques, en ajoutant des aspects génériques de chimie qui concernent directement l'environnement bâti et concernent des matériaux tels que le béton, l'acier, le bois et l'asphalte ;
—   prise en charge de l'interaction entre les objets, notamment les connexions, les interfaces et les ports ; les interactions étant définies comme des activités au cours desquelles se produit un transfert de matière, d'information, d'énergie ou de forces ;
—   prise en charge de la définition d'exigences non structurées interprétables par l'homme, provenant des besoins de la partie désignante, des lois et réglementations ou des recommandations du secteur ;
—   prise en charge des groupes implicites n'ayant pas de membres explicites (afin de modéliser des situations telles que « toutes les poutres principales d'un pont d'acier ») ;
—   prise en charge de la modélisation explicite des mesures en réutilisant l'ontologie W3C SOSA existante (en tant qu'ontologie allégée SSN mais de base et autonome) ;
—   prise en charge de la géométrie spatiale (localisation/forme) en réutilisant le langage GeoSPARQL (GML/WKT) de l'OGC et l'ontologie WGS84_pos (GPS).

European foreword
This document (prEN 17632-2:2023) has been prepared by Technical Committee CEN/TC 422 “Building
information modelling (BIM)”, the secretariat of which is held by SN - Norway.
This document is currently submitted to the CEN Enquiry.

Introduction
The abstract language and generic modelling patterns are already defined by the EN 17632-1:2022.
Early practical industrial application showed that there is a ‘gap’ between these abstract/generic patterns
and the real-world modelling needs in the built environment sector.
This document defines domain-specific extensions of the generic top level information model defined in
EN 17632-1:2022. These extensions are especially relevant for the modelling of assets/products in the
built environment. These extensions will support to close this gap.
This way, stakeholders in the built environment like owners, contractors and suppliers do not have to
‘reinvent the wheel’ for themselves for these new/extended modelling patterns.
By agreeing these patterns, stakeholders-specific data models will become even more pre-integrated
easing future asset/product data exchange/sharing and data integration/innovation in findable,
accessible, interoperable and reusable (FAIR) ways.
The extended standardized modelling patterns introduced in this document may be applicable to other
industry sectors as well.

1 Scope
This part 2 will provide extended semantic modelling patterns for (at least) the following domain-specific
asset aspects:
— Support for distinction between two subtypes of physical objects: spatial regions and real
(“tangible”) objects; the latter being discrete or continuous (“bulk matter”);
— Support for the materialization of physical objects, adding generic chemistry aspects directly
relevant for the built environment dealing with materials like concrete, steel, wood and asphalt;
— Support for the interaction between objects including connections, interfaces and ports. Interactions
being defined as activities where material, information, energy or forces are transferred;
— Support for the definition of unstructured, human-interpretable, requirements, coming from
appointing party needs, laws & regulations or sector recommendations;
— Support for implicit groups having no explicit members (to model situations like “all main girders of
some steel bridge”);
— Support for the explicit modelling of measurements reusing the existing W3C SOSA ontology (as a
lightweight but self-contained SSN core ontology).
— Support for spatial geometry (location/shape) reusing OGC GeoSPARQL (GML/WKT) and the
WGS84_pos ontology (GPS)
These modelling patterns (in bold below) can all be positioned in the global modelling framework
provided in the form of a taxonomy by Part 1. These leaf concepts form the primary table of content of
this part 2.

NOTE 1 The reused SOSA and GeoSPARQL entities will be kept separate. That means that the actual supertypes
as indicated above will not be modelled. Instead domain-specific concept can be subclasses or individuals can be
multiple typed.
NOTE 2 Some of the information needs might be resolved by extending existing language level constructs (like
in the case of implicit groups just adding some attributes for existing classes or containers or the use of SHACL rules
to represent structured requirements coming from clients, building laws and regulations or from building sector
recommendations). Finally there is a lot of ‘pattern potential’ under ‘DiscreteObject’ and ‘SpatialRegion’ in the built
environment (road networks, tunnels, bridges, buildings, installations). Care is taken not to cross existing standards
boundaries.
