New tool to report on completeness of open research information globally

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.

Integrating grant metadata for seamless research interconnectivity at FCCN|FCT

Click here for the version in Portuguese

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.

Enhancing repository integration with Crossref

Repositories are home to a wide range of scholarly content; they often archive theses, dissertations, preprints, datasets, and other valuable outputs. These records are an important part of the research ecosystem and should be connected to the broader scholarly record. But to truly serve their purpose, repository records need to be connected to each other, to the broader research ecosystem, and to the people behind the research. Metadata is what makes that possible. Enhancing metadata is a way to tell a fuller, more accurate story of research. It helps surface relationships between works, people, funders, and institutions, and allows us as a community to build and use a more connected, more useful network of knowledge - what Crossref calls the ‘Research Nexus’.

Documentation

DOI error report

The DOI error report is sent immediately when a user informs us that they’ve seen a DOI somewhere which doesn’t resolve to a website.

The DOI error report is used for making sure your DOI links go where they’re supposed to. When a user clicks on a DOI that has not been registered, they are sent to a form that collects the DOI, the user’s email address, and any comments the user wants to share. We compile the DOI error report daily using those reports and comments, and send it via email to the technical contact at the member responsible for the DOI prefix as a .csv attachment.

DOI not found

If you would like the DOI error report to be sent to a different person, please contact us.

The DOI error report .csv file contains (where provided by the user):

  • DOI - the DOI being reported
  • URL - the referring URL
  • REPORTED-DATE - date the DOI was initially reported
  • USER-EMAIL - email of the user reporting the error
  • COMMENTS

We find that approximately 2/3 of reported errors are ‘real’ problems. Common reasons why you might get this report include:

  • you’ve published/distributed a DOI but haven’t registered it
  • the DOI you published doesn’t match the registered DOI
  • a link was formatted incorrectly (a . at the end of a DOI, for example)
  • a user has made a mistake (confusing 1 for l or 0 for O, or cut-and-paste errors)

What should I do with my DOI error report?

Review the .csv file attached to your emailed report, and make sure that no legitimate DOIs are listed. Any legitimate DOIs found in this report should be registered immediately. When a DOI reported via the form is registered, we’ll send out an alert to the reporting user (if they’ve shared their email address with us).

I keep getting DOI error reports for DOIs that I have not published, what do I do about this?

It’s possible that someone is trying to link to your content with the wrong DOI. If you do a web search for the reported DOI you may find the source of your problem - we often find incorrect linking from user-provided content like Wikipedia, or from DOIs inadvertently distributed by members to PubMed. If it’s still a mystery, please contact us.
