Building Better Connections: The Story of Crossref's Metadata Development

Three years ago, we asked our members what they needed from Crossref’s metadata. We received confirmation that we were going in the right direction, as well as some new ideas to explore. This helped set the course for our metadata development work since then, and continues to guide where we’re headed next.

Collaboration with Knowledge Futures to build support for high-volume DOI registration

Cross-posted from the Knowledge Futures blog.

For many years, PubPub has made it possible for communities to assign DOIs to a range of outputs and component Pubs. Knowledge Futures and Crossref are building together to test the limits of what’s possible for high-volume, high-granularity DOI management. That means fast prototypes, real building, and learning through the process.

Co-access deprecation is coming: are you ready?

Last September, we announced we’d be deprecating co-access and encouraging its ~100 users to use our multiple resolution service. We announced that no new DOIs will be placed in co-access from 1st of July 2026 and that the ensuing 6 months should be spent cleaning up records already in co-access and moving them over to multiple resolution. 

We’re here with a reminder: co-access is being deprecated…and with an update: To help with the transition to multiple resolution, we offer a tool that simplifies the process and documentation about how to set up multiple resolution.

Two billion citation links in Crossref help research travel further

We’ve recently reached an important milestone for the research nexus: the works in our metadata corpus are now connected with over 2 billion citation links! This is a great opportunity to share a dedicated dataset and discuss why these are important for science.
