Full OpenURL metadata from CrossRef

·

Geoffrey Bilder mentions in a comment - and Chuck Koscher explains further - that the CrossRef OpenURL resolver/metadata server has a new parameter: format=unixref, that returns the full metadata for an item (though still not the citation count, which is reserved as an incentive for publishers to contribute, though Scopus has a more complete citation count anyway).

Now instead of
http://www.crossref.org/openurl/?noredirect=true&id=doi%3A10.1103%2FPhysRev.47.777

you can do
http://www.crossref.org/openurl/?noredirect=true&format=unixref&id=doi%3A10.1103%2FPhysRev.47.777

And it's an OpenURL resolver of course, so you can do
http://www.crossref.org/openurl/?noredirect=true&format=unixref&url_ver=Z39.88-2004&rft_id=info%3Adoi%2F10.1103%2FPhysRev.47.777

or even, with no identifier
http://www.crossref.org/openurl?noredirect=true&format=unixref&url_ver=Z39.88-2004&url_ctx_fmt=ori%3Afmt%3Akev%3Amtx%3Actx&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&rft.genre=article&rft.atitle=Can+Quantum-Mechanical+Description+of+Physical+Reality+Be+Considered+Complete%3F&rft.jtitle=Physical+Review&rft.volume=47&rft.issue=10&rft.spage=777&rft.epage=780&rft.date=1935&rft.au=A.+Einstein

and if you remove the noredirect parameter on any of the above, it functions like a normal OpenURL resolver and sends you directly to the article:
http://www.crossref.org/openurl?url_ver=Z39.88-2004&url_ctx_fmt=ori%3Afmt%3Akev%3Amtx%3Actx&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&rft.genre=article&rft.atitle=Can+Quantum-Mechanical+Description+of+Physical+Reality+Be+Considered+Complete%3F&rft.jtitle=Physical+Review&rft.volume=47&rft.issue=10&rft.spage=777&rft.epage=780&rft.date=1935&rft.au=A.+Einstein

which is ideal for use in a Greasemonkey script that creates OpenURL resolver links (which by the way is also updated to take advantage of the new getElementsByClassName if available) from COinS.
