Crossref introduces new Metadata APIs 'Plus' service, offering new features and richer metadata

Machine access to >90 million records about research outputs is now even easier

During its Annual Meeting, LIVE17, in Singapore on 15 November, Crossref announced a new paid-for service from January 2018 for machine access to metadata along with guaranteed uptime and priority support, with notifications of new matching records and 'snapshot' downloads to be added in the first quarter.

Publishers register content with Crossref by depositing metadata so that they don't have to make bilateral agreements with third parties, or each other. Crossref makes this metadata openly available via APIs so that people and machines around the world can incorporate it into their tools and services to aid research. This metadata can be retrieved via a choice of APIs to find, cite, link, and assess research outputs. It means that publishers only have to send the metadata to one place to have their content discovered and used by the thousands of tools and services that rely on Crossref as a source of information about research outputs.

Ginny Hendricks, Director of Member and Community Outreach at Crossref, comments "We receive over 600 million queries each month through our various human and machine interfaces and this is only rising. We're a sustainable community-governed not-for-profit, so this widespread use of our APIs helps the entire scholarly community rely on a single shared source of metadata, and create robust, persistent and accurate citations to and between our members' content. The new Plus service marks a significant milestone for Crossref as we place strategic emphasis on serving the users of our metadata."

Jennifer Kemp, Head of Business Development at Crossref, explains "Crossref's 92 million (and counting) metadata records provide information about about journal articles and preprints, books and book chapters, conference proceedings, standards, datasets, and reviews. And it's not just bibliographic metadata -- references, Cited-by counts, funding data, license information, full-text links, ORCID iDs, abstracts, and retractions and corrections -- are all available, if included in publisher metadata. This metadata remains free and open through Crossref's public APIs. Starting January 2018, anyone--from publishers, funders, research institutions, and others--can choose to pay an annual fee for guaranteed uptime, dedicated support, and soon after, volume downloads and notifications."

Kudos is the first organization to sign up. David Sommer, Co-Founder and Product Director, says "Our service has always ingested Crossref bibliographic metadata to reduce manual data entry for our users. We're excited to now be adding Crossref citations to the range of metrics we compile for users, and we're also pleased that Crossref is strengthening the services associated with its API."
