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.
