I think this highlights the point that, at some point, you have to model the data.

Subject: Re: [CODE4LIB] Representing geographic hiearchy in linked data
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.
