Ehdotuksen soveltamisala:
This document, EN 17632-2, provides semantic modelling patterns for (at least) the following asset aspects: • Support for distinction between 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 concrete, steel and asphalt; • Support for the interaction between objects including connections, interfaces and ports (parts of objects where such interaction can take place). Interaction being defined as activities where material, information, energy/forces are transferred; • Support for the definition of requirements, unstructured and structured, coming from client 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 Semantic Sensor Network (SSN)/Sensor, Observation, Sample, and Actuator (SOSA) ontology, incl. extended QUDT support. • Support for geospatial geometry (GeoSPARQL/wgs84) These patterns are currently inspired by NEN 2660-2 (that is itself finalized and tested in practice in parallel). These modelling patterns can all be positioned in the global modelling framework already provided in the form of the top level taxonomy by Part 1. Some of the information needs might be resolved by extending existing language level constructs. Finally there is a lot of ‘pattern potential’ under ‘Discrete Object’ and ‘Spatial Region’ in the built environment (road network, tunnel, bridge, road, building, installations). Care will be taken not to cross existing standards boundaries (like for open BIM and GIS).
