ČSN EN 17549-2

This document defines a Model View Definition (MVD) of the IFC schema defined in EN ISO 16739-1:2020. The MVD described by this document is designated as CODview2. This document focuses on core and resource classes and relies on external data dictionaries to describe construction specific semantics. NOTE 1 - Core classes are those defined in EN ISO 16739-1:2020, 5. NOTE 2 - Resource classes are those defined in EN ISO 16739-1:2020, 8. This document does not provide any construction object schema as it considers that these are already defined in data dictionaries compliant with EN ISO 12006-3:2022. This document focuses only on the format of the exchanged data and not on the way to process them. CODview2 does not support the geometrical representations of construction objects but allows the exchange of geometrical properties. These properties may be used to define geometrical representations of construction objects.
