Re: Need help mapping two letter country code to URI

Hugh

The actual problem, as is well shown by your sameas.org example, is not the
lack of URIs for countries, but to figure out which are "cool" (stable,
authoritative, published following best practices). sameas.org yields 23
URIs for Austria, 29 for France etc.
Supposing they are all really "equivalent" in the strong owl:sameAs sense,
any of those should do, but ...
On the other hand, maybe more authoritative sources are absent of the
sameas.org list, such as the excellent FAO ontology pointed by Dan. And
above all, which is definitely missing are sets of URIs published by ISO
itself.
There is an ongoing work aiming at authoritative URIs for ISO 639-2
languages by its registration authority at Library of Congress.
http://www.loc.gov/standards/iso639-2/. As I understand, those URI will be
published under http://id.loc.gov/authorities/, so watch this space. I cc
Rebecca Guenther who is in charge of this effort at LoC, she'll certainly be
able to provide update about this, and maybe she's aware of some equivalent
effort for ISO 3166-1. But according to an exchange I had with her a while
ago, ISO itself might be "years away" from publication under its own
namespace, unfortunately.
