In April 2025, we launched the metadata matching project, in order to add missing relationships to the scholarly metadata. We will do this by consolidating all existing and planned matching workflows, which enrich member-deposited metadata in Crossref. This unified service will result in a more complete research nexus. In this blog post, we share our latest milestone: developing and evaluating a strategy for matching funder metadata to Research Organization Registry (ROR) identifiers.
Preserving the integrity of the scholarly record is an important component of the overall endeavour to protect research integrity. Open scholarly infrastructure enables persistent recording of research objects and associated metadata, which provides an evidence trail for these objects for all in the research community. Crossref and DataCite – as providers of essential infrastructure for preservation of the scholarly record – we share our joint expertise in the new guide on “Why metadata matters for research integrity and how to contribute”.
As our global community continues to grow, it is important for us to build and maintain our connections within it. In March this year, we had the opportunity to visit São Paulo for a community event at the Fundação Getúlio Vargas. The content of our presentations is available online. Events such as this provide an opportunity for us to update our members on Crossref fundamentals and developments, and help us better tune in to the varied needs of our communities and learn how we can work together more effectively. This was our third visit to Brazil, with previous events held in Campinas and São Paulo in 2016, and Goiânia and Fortaleza in 2018.
Each organization in the global community of Crossref members (that’s currently over 24k organizations in 166 different countries) plays a key role in building the Research Nexus. Any opportunity we have to meet with our members in person is a highlight and a way for us to learn more from each other. The month of January saw three of us travel to Bangkok to attend the first-ever Charleston Conference organised in Asia and to meet with our growing community in Thailand.

These LINK tags are placed in the document HEAD section and could be used by crawlers and agents to recognize the work represented by the current document. This sounds like a great idea and we’d like to hear feedback on it.
Concurrently at Nature we have also been considering how best to mark up in a machine-readable way DOIs appearing within a document page BODY. Current thinking is to do something along the following lines:
which allows the DOI to be presented in the preferred Crossref citation format (doi:10.1038/nprot.2007.43), to be hyperlinked to the handle proxy server (<a href="http://dx.doi.org/10.1038/nprot.2007.43">http://dx.doi.org/10.1038/nprot.2007.43</a>), and to refer to a validly registered URI form for the DOI (info:doi/10.1038/nprot.2007.43). Again, we would be real interested to hear any opinions on this proposal for inline DOI markup as well as on Leigh’s proposal for document-level DOI markup.
(Oh, and btw many congrats to Leigh on his recent promotion to CTO, Ingenta.)
