At Crossref and ROR, we develop and run processes that match metadata at scale, creating relationships between millions of entities in the scholarly record. Over the last few years, we’ve spent a lot of time diving into details about metadata matching strategies, evaluation, and integration. It is quite possibly our favourite thing to talk and write about! But sometimes it is good to step back and look at the problem from a wider perspective.
This year’s public data file is now available, featuring over 156 million metadata records deposited with Crossref through the end of April 2024 from over 19,000 members. A full breakdown of Crossref metadata statistics is available here.
Like last year, you can download all of these records in one go via Academic Torrents or directly from Amazon S3 via the “requester pays” method.

Earlier this year, we reported on the roundtable discussion event that we had organised in Frankfurt on the heels of the Frankfurt Book Fair 2023. This event was the second in the series of roundtable events that we are holding with our community to hear from you how we can all work together to preserve the integrity of the scholarly record - you can read more about insights from these events and about ISR in this series of blogs.
Crossref is undertaking a large program, dubbed 'RCFS' (Resourcing Crossref for Future Sustainability) that will initially tackle five specific issues with our fees. We haven’t increased any of our fees in nearly two decades, and while we’re still okay financially and do not have a revenue growth goal, we do have inclusion and simplification goals. This report from Research Consulting helped to narrow down the five priority projects for 2024-2025 around these three core goals:
Funders are joining Crossref to register their grants so that they can more easily and accurately track the outputs connected to the research they support.
Once you’re a member, registering grants with us means giving us information about each awarded grant, including a DOI which uniquely and persistently identifies each record. You can use the grant registration form or direct XML deposit methods to deposit and update grant metadata. This section focuses on grants, but research funders can also register other record types such as reports, data, and working papers.
Decide which grants to register first, as you get into the swing of things. For example, pilot a particular country, or area of support. It’s better to start with newly-awarded grants, and then move on to older or long-running awards - these are cheaper to register, and are more likely to have produced research papers, so they’re great for demonstrating the full potential of connected research metadata.
A DOI is made up of a DOI resolver, a prefix, and a suffix. When you join Crossref as a member, we give you a DOI prefix. You combine this with a suffix of your choice to create a DOI. Although some funders choose to use their internal grant identifier as the DOI suffix, we advise you to make your suffix opaque, meaning that it does not encode or describe any information about the work. Your DOI becomes active once it is successfully registered with us. Read more about constructing your DOIs.
Should a grant move to a new landing page, the URL in the grant’s metadata is updated to point to the new location. There’s no charge to update metadata for existing deposits.
Grants can be registered for all sorts of support provided to a research group or individual, such as awards, use of facilities, sponsorship, training, or salary awards.
Here’s the section of our schema for grant metadata. If you’re working with a third-party system, such as Proposal Central or EuroPMC, they may be able to help with this piece of work.
Registering grant metadata using the grant registration form ``
You can use the grant registration form to register grants, with no prior knowledge of XML. You fill out the form and the XML is created for you in the background. You enter your account credentials and the metadata is submitted directly.
If you’d prefer to work directly with XML, you may be able to map your own data and identifiers to our schema. See our example deposit file - this is a full example, and many of the fields it contains are optional, but we encourage you to provide as much information as you can. Rich metadata helps maximum reuse of the grant records you register with Crossref. This .xsd file helps explain what goes into each field, and the parameters (length, format) of what is accepted in each field. Here’s a less techy version.
When you’ve created your XML files, use our checker to test them - this will show any potential errors with your files. For help with resolving problems, send your XML file and the error message to Support.
Once your submission is successful, your grant DOIs are ‘live’ and ready to be used. It’s good practice to add the grant DOI to the landing page for the grant, as in this example for https://doi.org/10.37717/220020589:
Let your grant submission systems, awardees, and other parties know you are supporting Crossref grant identifiers, and that they should start collecting these identifiers too. Crossref grant metadata (including grant DOIs) is made openly available through our APIs, so it can be used by third parties (including publishers, grant tracking systems) to link grants to related research outputs.
