add_partof_facet
Adds a partOf facet to buildingSMART IDS specifications to define containment relationships between building elements, ensuring compliance with IDS 1.0 standards.
Instructions
Add a partOf facet to a specification.
Args: spec_id: Specification identifier location: "applicability" or "requirements" relation: Relationship type (e.g., "IFCRELCONTAINEDINSPATIALSTRUCTURE") parent_entity: Parent entity name (e.g., "IFCSPACE") ctx: FastMCP Context (auto-injected) parent_predefined_type: Optional predefined type for parent cardinality: "required", "optional", or "prohibited"
Returns: {"status": "added", "facet_type": "partof", "spec_id": "S1"}

Implementation Reference
- The handler function that implements the core logic for adding a 'partOf' facet to an IDS specification. It retrieves the session and specification, creates a PartOf facet using the ifctester IDS library, appends it to the appropriate section (applicability or requirements), and returns success status.async def add_partof_facet( spec_id: str, location: str, relation: str, parent_entity: str, ctx: Context, parent_predefined_type: Optional[str] = None, cardinality: str = "required" ) -> Dict[str, Any]: """ Add a partOf facet to a specification.
