Hi,
I summarized my thoughts about identifiers for data formats in a blog
posting: http://jakoblog.de/2009/05/10/who-identifies-the-identifiers/
In short it’s not a technology issue but a commitment issue and the
problem of identifying the right identifiers for data formats can be
reduced to

This is unfortunately not the case.

As opposed to all the reasons for not doing it. :) This is crap design

The Amazon products API keeps changing it's name, and has just been
changed to Amazon "Product Advertising API" -- it's the one you use to
look up books in Amazon and get metadata for them, though.
It looks from an email I got from Amazon that ss of August 15th, you'll

Um, MODS is awfully useful for a bunch of reasons. I'm not going to stop
using it because they've used namespaces in a way

Agreed.

They're also tightened up the API in various ways, and renamed it the
"Amazon.com Product Advertising API." Although I know of no case when
Amazon has shut down a library, it would be hard for any to claim
their site had "as their principal purpose advertising and marketing

Good try, but as far as I've experienced, people in the librar
In fact, I believe that library-sector developers have asked Amazon and
been told that their use is allowed. But definitely, there's no
guarantee this will always continue be true. The terms of use don't seem
to have substantially changed to me, but they could always start
enforcing them more s

Their marginal cost may be quite low, but I'm fairly sure it's not
zero. Cycles, storage, and bandwidth aren't free.
Amazon has never struc
PS: If you do need to request a new API key, I reccommend when
describing the purpose of your use, you make sure to emphasize adding
links to Amazon to library pages. Which shouldn't be a lie, if you are
indeed doing that. I consider adding such a link a reasonable 'cost' of
using the API for i
