Hi, Thanks for the info, but it's not quite what I'm looking for. We've established authority control for ancient places, but I'm looking for an ontology I can use to describe the child:parent relationship between city and region or region and larger region (in any way that isn't dcterms:partOf). Geonames has defined their own vocabulary that can't really be reused in other geographic contexts, e.g. with gn:countryCode, gn:parentCountry.
