hi,
stumbled across your I-D "draft-daviel-html-geo-tag-00.txt" on the Web
(your site, not the IETF site).
Some comments:
1) This may be best done as a W3C activity, since they're doing most
HTML related stuff these days?
2) you might want to look at the various proposals for geodata representation
in the DNS, especially RFC 1712 and RFC 1876.
1876 in particular adds the encoding of extent - something I find
extremely interesting when talking about named entities - I don't
want the city of Trondheim reduced to a point in the town square, and
with extent, "overlaps", "within" and "near" are much more codifiable.
Have fun!
