Exactly - and how do we know about these ancient geographic entities (AGEs)? They are attested in a variety of sources on various types of evidence, and it maybe useful to be able to document which "version" of an AGE you are talking about because maybe different people had different views on the matter (or different finds point to different cultures in a strictly geographic region?!)... This is the kind of stuff that CIDOC-CRM-SIG had in mind when creating CRM because, well, that's what museum data is about... -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Ethan Gruber Sent: 10 April 2012 00:13 To: [log in to unmask] Subject: Re: [CODE4LIB] Representing geographic hiearchy in linked data Ancient geographic entities. Athens is in Attica. Sardis is in Lydia (in Anatolia, for example). If these were modern geopolitical entities, I would use geonames. We're linking cities to Pleiades, but Pleiades does not maintain parent::child geographic relationships.
