type: NamedIndividual
type: CodeVerticalStructureMaterialType
comment: Pieces of rock or mineral substance (other than metal) of definite form and size, usually artificially shaped, and used for some special purpose. Used, for example, for building, for paving, or in the form of a block, slab, or pillar set up as a memorial and/or a boundary-mark.
