1. A system that uses universal location referencing objects to provide geographic item information for a location, comprising: an interface to a file-of-reference that comprises geographic item information, including a geographic item associated with a location; an interface to a third-party file that comprises additional geographic item information that may be associated with the location; a universal location reference object that includes (a) a universal location reference code that uniquely identifies the location, (b) identifying information for the location, and (c) links to the additional geographic item information in the third-party file; a logic that, in response to a request for information for a particular location, retrieves a universal location reference object for the particular location, traverses the links, associates the additional geographic item information in the third-party file with the geographic item information in the file-of-reference, and provides the resultant information as a response to the request.
