This is an experiment to use Geohash as an identifier of a spatial thing, rather than a service page URI.
You may want to try a geohashuri bookmarklet which extracts Geohashed URI from an hCalendar microformat ('vevent' class should be on either div or h2 element. Only first 'vevent' will be extracted). For example, test this bookmarklet on ISWC 2008 page.This is The Web KANZAKI . ©2008 by MK.
