The Crossref Curriculum

UNIXREF query output format

Our unified XML (UNIXREF) format returns all metadata submitted by the member responsible for a DOI. The UNIXREF data does not include namespaces or namespace prefixes, which are used extensively for non-bibliographic metadata.

The UNIXREF format will return deposited citations if the depositing member has enabled reference distribution for their prefix. Citations will also be returned to members querying for their own deposited data.

UNIXREF schema

The majority of UNIXREF results use the unixref1.1.xsd schema (schema | documentation). Some results involving book or conference proceeding data deposited prior to a deposit schema change use unixref1.0.xsd (schema | documentation).
