unapi-enabled amazon.com with OPA proxy.

I put together an unapi-enabled amazon page, it uses Dan's OPA-0.1 server as proxy [http://onebiglibrary.net/story/opa-release-0.1].

Again I am following Dan's previous Amazonmixer script [http://curtis.med.yale.edu/dchud/log/project/rogue/amazon-coinspmh-enabled,

See a screenshot below:


To try it out:

1. Install greasemonkey, restart firefox, come back here, etc
2. Install amazon_opa.user.js
3. Install unapi_link.user.js
4. Visit an amazon book page, such as http://www.amazon.com/gp/product/0131103628/104-2542103-6763135

Notice the sequence of operation is important.

so I did nothing new but to demonstrate the system can work ;-) There is a small problem with list of metadata formats supported at a site, since OPA 0.1 returns an empty list for the site. In this version I use listformats response from first available URI. I think we still need a little clarification between listformats for a site and an identifier.
