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.
Welcome back to our series of case studies of research funders using the Grant Linking System. In this interview, I talk with Cátia Laranjeira, PTCRIS Program Manager at FCCN|FCT, Portugal’s main public funding agency, about the agency’s approach to metadata, persistent identifiers, Open Science and Open Infrastructure.
With a holistic approach to the management, production and access to information on science, FCCN|FCT’s decision to implement the Grant Linking System within their processes was not simply a technical upgrade, but a coordinated effort to continue building a strong culture of openness. With the mantra “register once, reuse always”, FCCN|FCT efforts to embrace open funding metadata was only logical.
In 2022, we flagged up some changes to Similarity Check, which were taking place in v2 of Turnitin’s iThenticate tool used by members participating in the service. We noted that further enhancements were planned, and want to highlight some changes that are coming very soon. These changes will affect functionality that is used by account administrators, and doesn’t affect the Similarity Reports themselves.
From Wednesday 3 May 2023, administrators of iThenticate v2 accounts will notice some changes to the interface and improvements to the Users, Groups, Integrations, Statistics and Paper Lookup sections.
Logging in
iThenticate v2 account administrators and browser users will see a new login page when logging in to iThenticate v2:
A refreshed interface
Once logged in to iThenticate v2, account administrators will see an updated design, with improved notifications to let them know whether a task/action has been successfully completed or not.
Users
There will be improvements to the user management system for account administrators, including a much clearer navigation menu for managing active, pending and deactivated users.
There will also be a filtering option on the Users page to search for active, pending and deactivated users by first name, last name, email address, group and date added. In addition coloured labels will be introduced to easily identify the level of access (or ‘Role’) for each user.
An improved bulk user import process will be available, with clearer guidance on any issues that may arise during the upload. This new development will also include new screens for adding and editing users with more notifications to help prevent mistakes.
Integrations
For account administrators managing peer review management system integrations and needing to generate API keys, the Integrations page will be improved to make copying API keys simpler.
Statistics
iThenticate v2 administrators will also notice some improvements to the Statistics page. Usage data should load faster and will be sortable by user group. They will also be able to generate large usage reports of over 100k submissions.
Paper lookup
The Paper lookup will allow iThenticate v2 account administrators to find submissions that have been made from any integration connected to their iThenticate v2 account. They can be found by searching the paper ID (or oid number) of the submission.
Please note: the ability to search for submissions by the user’s name is available for manuscripts submitted via the iThenticate v2 website only and not for papers submitted via an integration.
New password requirements
To improve the security of users’ accounts, new password requirements will be introduced, including a minimum of 8 symbols, 1 special symbol, 1 upper case letter, and 1 number.
Next in iThenticate v2
Turnitin, who produce iThenticate, are currently working on a number of new features and developments including an improved similarity report, paraphrase and AI writing detection. A detailed timeline is not yet available but we’ll be updating you on these new developments in the coming months.
