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).
