Class: FurnitureItem
Structural furniture: chairs, tables, beds, wardrobes, shelving. COICOP 05.1 (furniture and furnishings). Grounded in Product Types Ontology:
http://www.productontology.org/id/Furniture
Assessment: FurnitureAssessmentEnum (structured structural assessment). Structural soundness is the primary redistribution signal for furniture — a scratched but solid chair is redistributable; a wobbly but clean one is not. assessment_result required regardless of usage because new flatpack furniture can have manufacturing defects or assembly issues.

description: Type-defining slot on DonationItem. Value is the class URI of the
concrete subclass (e.g. inkind_knowledge_repo:ClothingItem). linkml-validate,
gen-json-schema, and gen-pydantic all use this slot to dispatch to the correct
subclass schema and valid slot set. For other entities (DemandSignal, StorageLocation)
the range is overridden via slot_usage to CategoryEnum.
notes:
- Due to a limitation in LinkML, the designates_type annotation was removed because
the range is an Enum and not a string.
