TL;DR. Metadata Manager will be retired at the end of 2025. Over the past four years, we have been developing a new helper tool to replace it, and that tool has now reached a stage of maturity that means we will be able to switch off Metadata Manager by the end of the year.
Our REST API makes all of the metadata we hold publicly available. It receives the majority of our API traffic, with around 1 billion hits per month. It’s one of the key ways that we fulfil our mission to make research objects easy to find, cite, link, assess, and reuse. From 1 December 2025, we will be revising the rate limits for the public and polite pools of the REST API to ensure that we can maintain a stable and reliable system, and that metadata is freely available to everyone.
Noyam Journals, based in Accra, Ghana, was recently recognised for the completeness of its metadata through the Crossref Metadata Award, part of our 25th anniversary celebrations. Noyam was one of six publishers worldwide to receive the award and stood out as a leader among members of our Global Equitable Membership (GEM) Program.
Wednesday 22nd October 2025—Crossref, the open scholarly infrastructure nonprofit, today releases an enhanced dashboard showing metadata coverage and individual organisations’ contributions to documenting the process and outputs of scientific research in the open. The tool helps research-performing, funding, and publishing organisations identify gaps in open research information, and provides supporting evidence for movements like the Barcelona Declaration for Open Research Information, which encourages more substantial commitment to stewarding and enriching the scholarly record through open metadata.
Learn more about conflicts and the conflict report. Conflicts are usually flagged upon deposit, but sometimes this doesn’t happen, creating a missed conflict.
A missed conflict may occur for several reasons:
Two DOIs are deposited for the same item, but the metadata is slightly different (DOI A deposited with an online publication date of 2011, DOI B deposited with a print publication date of 1972)
DOIs were deposited with a unique item number. Before 2008, DOIs containing unique item numbers (supplied in the <publisher_item> element) were not checked for conflicts.
The missed conflict report compares article titles across data for a specified journal or journals. To retrieve a missed conflict report for a title:
The missed conflict interface will pop up in a second window. Enter your email address in the appropriate field. Multiple title IDs can be included in a single request if needed
A report will be emailed to the email address you provided. This report lists all DOIs with identical article titles that have not been flagged as conflicts.
