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.
Please help us welcome new faces at Crossref! Martyn, Sara, Laura, and Mark joined us very recently and we are happy they’re with us. Both Martyn and Sara have joined the Product team and this has given us the chance to reorganize the team into the following groups: content registration, scholarly stewardship, scholarly impact, metadata retrieval, and UX/UI leadership. Laura joined the Finance and Operations team to help make the billing process simple for our members. Mark joins the Technology team and one of his projects will be improving the Event Data service.
It is exciting to already see the impact of your contributions and look forward to what’s to come!
And now a few words from each of them.
Martyn Rittman
I am a former university researcher who worked on interdisciplinary projects around life sciences and analytical chemistry, with positions in the UK and Germany. I spent seven years at open access publisher MDPI doing everything from running journals to handling production, developing services for authors and publishers, and supporting preprints. I’m very excited to be joining Crossref as a Product Manager and developing some great products and services that focus on how Crossref-indexed research creates impact. This includes supporting the use of preprint metadata. I’m also looking forward to getting my teeth into event data, which looks at how those in the research community and beyond reference, use, and reuse research. If you are interested in making use of event data or have examples of event data applications, I would like to hear from you.
Sara Bowman
I’m thrilled to have joined Crossref at this exciting time in the organisation. As a member of the Product team, my primary area of focus is content registration, building, and improving tools for our members to deposit rich metadata. I’m particularly interested in how we can create a unified user experience for content registration while supporting the needs of our diverse membership. A scientist by training, I’ve spent the last 6 years working on open source technologies to support scholarly communication, most recently in the role of Product Manager at the Center for Open Science. I’m passionate about open tools and using data to drive product development, building innovative solutions to improve research and scholarly communication.
Laura Cuniff
I joined Crossref two months ago as a part-time Billing Support Specialist on the Finance and Operations team. With the help of my supportive and knowledgeable colleagues, I took on learning the various systems. My goal is to make the billing process as simple as possible for our members by researching, retrieving, and relaying billing information. This allows our members to focus on the reason for their engagement with Crossref. With several part-time jobs cobbled together at different times of the day, I have the flexibility to volunteer with a few organisations in my hometown of Ipswich, MA. If you find yourself at the Ipswich Visitor Center, I may greet you, recommend the most beautiful spots in town, give you a tour of the Ipswich Museum, or send you off with a wonderful Ipswich Humane Group cat or dog! I’m very excited to be here!
Mark Woodhall
I am an open-source enthusiast who has worked in a range of technology roles at a variety of companies as a polyglot programmer with experience in Clojure(Script), Java, C#, and JavaScript. It’s really exciting to be working at Crossref as a Senior Software Developer on the Technology team and I’m proud to be part of a team with open source at its heart. I’m really looking forward to getting more involved with event data and building a scalable solution to support its future uses.
Welcome to the Crossref community Martyn, Laura, Sara, and Mark.
