[Esip-preserve] DOI resolution and content negotiation

[Curt Tilmes]

Here is some information about DOI Content Negotiation through the
dx.doi.org server:
http://crosscite.org/cn/

For example, for a paper: doi:10.1073/pnas.1015619108

If you go to:
      http://dx.doi.org/10.1073/pnas.1015619108
it will redirect to the publisher's page about that article that lets
you download the article, but if you ask for JSON, you get the
bibliographic citation information:

curl -LH "Accept: application/vnd.citationstyles.csl+json"
http://dx.doi.org/10.1073/pnas.1015619108

{
      "volume":"108",
      "issue":"27",
      "DOI":"10.1073/pnas.1015619108",
      "URL":"http://dx.doi.org/10.1073/pnas.1015619108",
      "title":"Climate related sea-level variations over the past two
millennia",
      "container-title":"Proceedings of the National Academy of Sciences",
      "publisher":"Proceedings of the National Academy of Sciences",
      "issued":{"date-parts":[[2011,7,5]]},
      "author":[
          {"family":"Kemp","given":"A. C."},
          {"family":"Horton","given":"B. P."},
          {"family":"Donnelly","given":"J. P."},
          {"family":"Mann","given":"M. E."},
          {"family":"Vermeer","given":"M."},
          {"family":"Rahmstorf","given":"S."} ],
      "editor":[],
      "page":"11017-11022",
      "type":"article-journal"
}

It will also format the citation to that reference as text for you:
curl -LH "Accept: text/x-bibliography; style=apa"
http://dx.doi.org/10.1073/pnas.1015619108
Kemp, A. C., Horton, B. P., Donnelly, J. P., Mann, M. E., Vermeer, M.,
& Rahmstorf, S. (2011). Climate related sea-level variations over the
past two millennia. Proceedings of the National Academy of Sciences,
108(27), 11017-11022. doi:10.1073/pnas.1015619108

Pretty neat.  (Also try it with text/turtle or application/rdf+xml or my
personal favorite, application/x-bibtex)

I tried it with an ORNL DOI and get back some basic metadata:

curl -LH "Accept: application/vnd.citationstyles.csl+json"
http://dx.doi.org/10.3334/ORNLDAAC/1096
{
      "type":"misc",
      "DOI":"10.3334\/ORNLDAAC\/1096",
      "URL":"http:\/\/dx.doi.org\/10.3334\/ORNLDAAC\/1096",
      "title":"NACP FOREST AGE MAPS AT 1-KM RESOLUTION FOR CANADA (2004)
AND THE U.S.A.(2006)",
      "publisher":"ORNL Distributed Active Archive Center",
      "issued":{"raw":"2012"},
      "author":[{"literal":"Environmental Sciences Division, Oak Ridge
National Laboratory"}]
}

datacite also has a content resolver described here:
http://data.datacite.org/static/index.html

http://data.datacite.org/application/rdf+xml/10.3334/ORNLDAAC/1096
returns this:

I'm wondering if we could use something like these to have a
well-defined way to get from our ESDIS DOIs to the ISO metadata, then
to other NASA PCS artifacts.

There is a bunch more info linked to those pages I haven't had much time 
to look into yet.
