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.
On September 1st we completed the final stage of the Crossmark v2.0 release and sent an email to all participating publishers containing instructions for upgrading. The first phase of v2.0 happened when we changed the design and layout of the Crossmark box back in May of this year. That allowed us to better display the growing set of additional metadata that our members are depositing, and saw the introduction of the Linked Clinical Trials feature.
Now all publishers have the opportunity to complete the upgrade by simply replacing the Crossmark button and the piece of code that calls the box. The new button designs are, we think, a much better fit for most websites, and are designed to look more like a button than a flat logo. The new buttons are also available as .eps files for placement in PDFs.

Most importantly, switching to 2.0 makes the Crossmark box responsive for better display on mobile devices.

Just two weeks after the code release a number of publishers have already upgraded and are running Crossmark 2.0 on their content. Congrats to the Pan African Medical Journal who were the first member to upgrade just a couple of days after the release. Â Of course we realise that many members will need time to schedule the upgrade, and while we are keen to see as many early adopters as possible, we will support version 1.5 of Crossmark through to the end of March 2017.
If your content is running Crossmark 2.0 we would love to see it. Drop us a line or put a link in the comments below.
