PID strategies are being written around the world right now, and the decisions being made will shape the scholarly record for decades. After 25 years running open scholarly infrastructure—now on behalf of 25,000 members in 167 countries—Crossref has an informed perspective on what those decisions should ideally rest on. Today we’re setting it out in our’s first position paper: Persistent identifiers in research infrastructure policy: the need for a holistic approach. You can read it online or download the PDF; it’s a 16-minute read.
Research is rarely limited to a single contributor performing a single role. Behind every research output are people contributing in various ways: software development, data analyses, methodology design, and much more. Often, the same person contributes in several of these ways. Until now, Crossref metadata could only capture part of that picture, but this is changing with Schema 5.5.
Through user experience research (UXR) initiatives that take into account our diverse membership and community, we can have a continuous, deeper understanding of the role of metadata in our members’ workflows, and ensure that our work continues to meet our community’s needs. Your support is the key to this process, and will positively impact the wider community - and if you’d like to start today, you can take part in our latest initiative: help us improve our Events page by sharing your thoughts on the page’s feedback form.
Our 2026 Community Update took place on 13 May. Two calls, one for the eastern and one for the western time zone, highlighted how our global community is growing, how we’re refining the metadata that supports trust in the scholarly record, and connecting records more effectively through our latest tools.

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://0-dx-doi-org.oasis.unisa.ac.za/10.1038/nprot.2007.43">http://0-dx-doi-org.oasis.unisa.ac.za/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.)
