I'd like to use a URI scheme to enable the users of one of my apps to share geographic locations.
I don't want to invent my own URI scheme and "geo" seems the most appropriate but there are only two Internet Drafts on the subject (draft-mayrhofer-geo-uri-01, draft-mayrhofer-geo-uri-02), both expired and wildly different in the way they approach the standard.
Is there an URI that's suited for encoding latitude and longitude and that made it as an RFC? Should I use a generic URI such as the tag URI scheme?
