I’d like to request an api method that publishes a classification schema (or reference with sub elements) to an IFC snippet, such as a representative extract below. This would be a lot more efficient than having to traverse an entire classification using hundred or thousands of api calls.
<IfcClassificationReference Identification="Table 1" Name="Table 1 - Elements">
<HasReferences>
<IfcClassificationReference Identification="(2-)" Name="Primary elements, Carcass">
<HasReferences>
<IfcClassificationReference Identification="(21)" Name="External walls">
<HasReferences>
<IfcClassificationReference Identification="(21.0)" Name="External walls, general" />
<IfcClassificationReference Identification="(21.1)" Name="External walls, non-load bearing">
<HasReferences>
<IfcClassificationReference Identification="(21.10)" Name="External walls, non-load bearing, general" />
<IfcClassificationReference Identification="(21.11)" Name="External walls, non-load bearing, massive walls" />
</HasReferences>
</IfcClassificationReference>
<IfcClassificationReference Identification="(21.2)" Name="External walls, load bearing">
<HasReferences>
<IfcClassificationReference Identification="(21.20)" Name="External walls, load bearing, general" />
<IfcClassificationReference Identification="(21.21)" Name="External walls, load bearing, massive walls" />
