Ocean_City,_Maryland uses Infobox_Settlement, which has no mapping for 'state', while Thibodaux,_Louisiana uses Geobox, which does. Infobox_Settlement (for that page) has: |subdivision_type1 = [[Political divisions of the United States|State]] |subdivision_name1 = [[Maryland]] which requires a set of conditional mappings, repeated for each of the numbers appended, while Geobox has: | state = Louisiana which is trivial to map. > Question2: > There is no the class "State" in the dbpedia owl ontology, which is very > inconvenient.

It's still not 'city', as you expected, but that's down to Wikipedia.
