The Dublin Core metadata set contains a "coverage" element, with 
placeName, x.min, x.max, polygon etc. subelements. Syntax is
not finalized; one version of a draft is at

It is my understanding that one may use DC.coverage.x (.y,.z) to define 
a point, DC.coverage.x.min etc. to define a rectangular area,
and DC.coverage.polygon to define an irregular polygonal area.

Other metadata sets exist in the GIS community, e.g. FGDC, which define
similar elements.

The Maple Square project at Sympatico in Canada has defined a 
NAME="Location" META tag with content "Country, Province, City", I believe
for use with their URL acceptance robot.

There are a few links to other sites at the end of the coverage draft.

MCF defines a coding format. DC elements can be used within MCF coding
as well as within HTML META tags and other coding/transport mechanisms.
