IFC classifications

What CORENET X checks is the classification an element is exported with — its IFC entity and SubType — not the component name. This index lists every classification the corpus holds, grouped by entity. An element in the model picks up the parameters of each row matching its entity and SubType; a row whose classification is not in the model asks for nothing. One component often has several rows: a main element and its sub-components (Household Shelter: the space, its walls and slabs, its outlets), or one table per discipline, shown in Scope (Wall and Staircase: architectural model / structural model). The same entity can also appear under several components (IfcSlab: Slab, Accessible Route, Household Shelter, Prefabricated Building Systems).

Must fill counts the parameters the component's own page says must be filled (glossary_mandatory). 182 classifications across 55 IFC entities.
