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.
Sponsors make Crossref membership accessible to organisations that would otherwise face barriers to joining us. They also provide support to facilitate participation, which increases the amount and diversity of metadata in the global Research Nexus. This in turn improves discoverability and transparency of scholarship behind the works.
We began our Global Equitable Membership (GEM) Program to provide greater membership equitability and accessibility to organisations in the world’s least economically advantaged countries. Eligibility for the program is based on a member’s country; our list of countries is predominantly based on the International Development Association (IDA). Eligible members pay no membership or content registration fees. The list undergoes periodic reviews, as countries may be added or removed over time as economic situations change.
In January 2023, we began our Global Equitable Membership (GEM) Program to provide greater membership equitability and accessibility to organisations located in the least economically advantaged countries in the world. Eligibility for the program is based on a member’s country; our list of countries is predominantly based on the International Development Association (IDA). Eligible members pay no membership or content registration fees.
The list undergoes periodic reviews, as countries may be added or removed over time as economic situations change. Sri Lanka was added to the GEM program in March 2023 as they were recategorised to the IDA classification by the World Bank.
Some small organisations who want to register metadata for their research and participate in Crossref are not able to do so due to financial, technical, or language barriers. To attempt to reduce these barriers we have developed several programs to help facilitate membership. One of the most significant—and successful—has been our Sponsor program.
Sponsors are organisations that are generally not producing scholarly content themselves but work with or publish on behalf of groups of smaller organisations that wish to join Crossref but face barriers to do so independently. Sponsors work directly with Crossref in order to provide billing, technical, and, if applicable, language support to Members.
When Crossref began over 20 years ago, our members were primarily from the United States and Western Europe, but for several years our membership has been more global and diverse, growing to almost 18,000 organisations around the world, representing 148 countries.
As we continue to grow, finding ways to help organisations participate in Crossref is an important part of our mission and approach. Our goal of creating the Research Nexus—a rich and reusable open network of relationships connecting research organisations, people, things, and actions; a scholarly record that the global community can build on forever, for the benefit of society—can only be achieved by ensuring that participation in Crossref is accessible to all. Building a network for the global community must include input from all of the global community.Â
