Also, there is Geonames (http://www.geonames.org), which is the primary geographic data set on the Semantic Web. Here is the link to Athens: http://www.geonames.org/search.html?q=athens&country=GR kc On 4/6/12 4:54 PM, Karen Miller wrote: > Ethan, have you considered Getty's Thesaurus of Geographic Names?

I'm looking for an ontology that can describe geographic hierarchy, and hopefully someone on the list has experience with this. For example, if I have an RDF record that describes Athens, I want to point Athens to Attica, and Attica to Greece, and so on. The current proposal is to use dcterms:partOf, but the problem with this is that our records will also use dcterms:partOf to describe a completely different type of relational concept, and it will be almost impossible for scripts to recognize the difference between these two uses of the same DC term. > > Thanks, > Ethan -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
