I'm looking for an ontology containing geographical knowledge. In particular I'd like to have these types of information:
For example, starting from the node "New York" I'd like to be able to find parents like the New York state, the USA etc, and children like Manhattan, Bronx, etc. I couldn't find anything open-source/free to use. I know that a lot of researchers extract such information from Wikipedia, but I couldn't find any off-the-shelf packages to use. I also checked OpenStreetMap, which is great for the amount of data but doesn't seem to contain a proper geographical ontology.
Even a web service would be good!
Any hints? Mulone

A geospatial ontology represents geospatial concepts and properties for use over the Web and is key for successful implementation of the Geospatial Semantic Web.
geonames maintains a large hierarchical feature list which has a corresponding ontology. rdf, web services, etc... It has all the sorts of things that you list wanting and more.
