Q

How to use XML API URL, doi.crossref.org/search/doi?doi={doi}, for DOI-to-metadata query?

A

XML API URL doi.crossref.org/search/doi?doi={doi} allows you to query for metadata of a given DOI and receive output in XML format.

This XML API supports the following parameters: 

pid={email} - Required. The email address to identify yourself.
doi={doi} - Required. The DOI of the research paper.
format={format} - Optional. The format for the returning XML: xsd_xml, unixsd or unixref.

Here is an example of how to use the XML API with the default format, which is a simple text format, not XML: 

fyicenter$ curl 'https://doi.crossref.org/search/doi?pid=email@address.com&doi=10.1577/H02-043'
 
<?xml version="1.0" encoding="UTF-8"?>

      <year media_type="print">2003</year>
      <publication_type>full_text</publication_type>
      </query>
    </body>
  </query_result>
</crossref_result>
