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.

Private Repository - ScholarOne only
The Submitted Works repository (or Private Repository) is a new feature in iThenticate 2.0. The only MTS that currently integrates with this feature is ScholarOne. This feature allows users to find similarity not just across Turnitin’s extensive Content Database but also across all previous manuscripts submitted to your iThenticate account for all the journals you work on. This would allow you to find collusion between authors or potential cases of duplicate submissions.
How does this work?
You have received a manuscript from Author 1 and have decided to index this manuscript into your Submitted Works repository. At some point later you receive a new manuscript from Author 2. When generating your Similarity Report, you have decided to check against your Submitted Works repository. There is a paragraph in the manuscript from Author 2 which matches a paragraph in the manuscript from Author 1. This would be highlighted within your Similarity Report as a match against your Submitted Works repository.
By clicking on this match you can see the full text of the submission you’ve matched against:
And details about the submission, such as the name and email address of the user who submitted it, the date it was submitted and the title of the submission:
The ability to see the full source text and the details can both be switched off individually.
Setting up the Submitted Works repository
If you are using a third party integration then you should have options inside your MTS when setting up your configuration with iThenticate to decide whether submissions will be indexed to the Submitted Works repository and whether generated Similarity Reports will match against the Submitted Works.
Important: This feature means that sensitive data could be shared between different journals using your iThenticate account
The Submitted Works repository is shared across your entire iThenticate account. This means regardless of whether a submission was made natively from the iThenticate website or through an integration, all Similarity Reports which match against the Submitted Works repository will potentially match against any submissions which were indexed within it. This means that an editor working on one journal may be able to view submissions for another journal. If you are worried about giving your users access to sensitive data, we recommend switching this functionality off.
Submitted Works repository FAQs
Q. How much does this feature cost to use?
This feature comes free with every iThenticate 2.0 account.
Q. How many submissions can I index to my private repository?
There is no limit to the number of submissions you can index.
Q. Can I delete submissions from my private repository?
Yes. An Administrator can find and delete a submission using the Paper Lookup Tool. Go to Turnitin’s help documentation for more information.
