Yahoo Internet Location Platform API - Developers

Yahoo Internet Location Platform
From their site: a resource for managing all geo-permanent named places on Earth. Our purpose in creating the Internet Location Platform is to provide the Yahoo! Geographic Developer Community with the vocabulary and grammar to describe the world's geography in an unequivocal, permanent, and language-neutral manner. The Internet Location Platform is designed to facilitate spatial interoperability and geographic discovery; users can traverse the spatial hierarchy, identify the geography relevant to their users and their business, and in turn, unambiguously geotag, geotarget, and geolocate data across the Web.
