Module data_model 

Data model extraction service - extracts properties, relationships, and spatial hierarchy.

Re-exports

pub use rooted::DataModelEntities;

pub use types::*;

Modules

classifications 🔒

Classification association extraction.

documents 🔒

Document association extraction.

generated 🔒

Generated tables for the data-model service (see the sibling files’ headers for their generator scripts).

material_units 🔒

Per-owner length units for material layers in federated, multi-project IFC.

materials 🔒

Material association extraction.

metadata 🔒

Entity metadata extraction.

properties 🔒

Property set extraction.

property_value 🔒

Property VALUE resolution: turning a decoded IfcProperty attribute (nominal value, enumerated/list members, complex-property nesting) into the display string + kind + measure tag + candidate list that properties::extract_property wires onto a Property. Split out of properties.rs to keep entity-shape extraction (which pset/property to walk) separate from value-shape resolution (how to stringify one).

quantities 🔒

Quantity set extraction.

relationships 🔒

Relationship extraction.

rooted 🔒

Which rows the data model’s entities table carries (issue #6034).

spatial 🔒

Spatial hierarchy extraction.

types 🔒

Data model DTO structs shared by the extractor submodules.

Functions

extract_data_model

Extract complete data model from IFC content.

read_logical 🔒

Read an IfcLogical / IfcBoolean attribute as a tri-state Option<bool> (.U. / absent → None).

related_object_ids 🔒

Collect the RelatedObjects (attribute 4) entity ids of an IfcRelAssociates*.
