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.
To work out which version you’re on, take a look at the website address that you use to access iThenticate. If you go to ithenticate.com then you are using v1. If you use a bespoke URL, https://crossref-[your member ID].turnitin.com/ then you are using iThenticate 2.0.
The Settings tab controls general, document, and report display options. These options include the number of documents shown for each page, default report view, and controlling email notifications.
General settings (v1)
Use General settings to set your home folder - this is the folder will open by default when you log in to iThenticate. Choose your home folder from the drop-down menu.
From the Number of documents to show drop-down, choose how many uploaded documents are listed in your folders before a new page is created.
Choose what is displayed after you upload a document to iThenticate: Display the upload folder (to see the processing of the document you have just uploaded), or Upload another document (returns you to the upload form).
You can also choose the time zone and language for your account - the language you choose will set the language of your user interface.
Click Update Settings to save your changes.
Documents settings (v1)
Use Documents settings to choose the default way iThenticate sorts your uploaded documents: by processed date, title, Similarity Score, and author. Choose your preferred option from the drop-down menu.
You can set the threshold at which the Similarity Score color changes, based on the percentage of similarity. All Similarity Scores above the percentage you set will appear in the folder in blue, all those beneath the percentage will appear in gray. This visual distinction helps you easily identify matches above a given threshold. Learn more about how to interpret the Similarity Score.
Click Update Settings to save your changes.
Reports settings (v1)
Use Reports settings to adjust your email notifications, choose whether to color-code your reports, and view available document repositories for your account.
Email notifications tell you when a Similarity Report has exceeded particular thresholds, including Similarity Reports in shared folders. Email notifications are sent to the email address you used to sign up to iThenticate.
Report email frequency: choose whether to receive notifications, chose how often you would like to receive them every hour, once a day, every other day, or once a week
Similarity Report threshold: this refers to a paper’s overall Similarity Score. If the Similarity Score of a paper in your account exceeds the threshold set, you will receive an email notification. The default setting is ‘don’t notify me’.
Content tracking report threshold: this refers to the All Sources section of the Similarity Report. If a single source for a paper in your account exceeds the similarity threshold set, you will receive an email notification. The default setting is don’t notify me.
Color code report: color-coding the Similarity Report can make viewing matches easier. Choose Yes or No to enable or disable this feature.
Available document repositories: this section shows the available repositories for your account. Modify them in the folder settings.
