The XML API supports XML-formatted querying. XML queries give you significant control over the DOI matching process. The XML API is designed to (typically) return only one DOI, the one that best fits the metadata supplied in the query, and is therefore suitable for automated matching. Query results are returned in XML and will contain a full or abbreviated metadata record for matched items, depending on the request. The query input schema file is crossref_query_input2.0.xsd (documentation).
The XML API also supports DOI-to-metadata queries.
The following resources are available:
- XML query examples
- Controlling query execution
- Querying for books
- Querying with formatted citations
- DOI-to-metadata queries
- Author / article title queries
