An example would be the union of a spatial point and a spatial line that doesn't overlap the point, or two spatial lines that intersect at a single point. In both cases the resultant spatial region is neither 0-dimensional, 1-dimensional, 2-dimensional, or 3-dimensional."@en . _:b16252177 <http://www.w3.org/2002/07/owl#annotatedSource> <http://purl.obolibrary.org/obo/BFO_0000006> . _:b16252177 <http://www.w3.org/2000/01/rdf-schema#comment> "per discussion with Barry Smith" .
