Feedback on Automatic Digital Preservation and Self-Healing DOIs

Thank you to everyone who responded with feedback on the Op Cit proposal. This post clarifies, defends, and amends the original proposal in light of the responses that have been sent. We have endeavoured to respond to every point that was raised, either here or in the document comments themselves. We strongly prefer for this to be developed in collaboration with CLOCKSS, LOCKSS, and/or Portico, i.e. through established preservation services that already have existing arrangements in place, are properly funded, and understand the problem space.

2023 board election slate

I’m pleased to share the 2023 board election slate. Crossref’s Nominating Committee received 87 submissions from members worldwide to fill seven open board seats. We maintain a balance of eight large member seats and eight small member seats. A member’s size is determined based on the membership fee tier they pay. We look at how our total revenue is generated across the membership tiers and split it down the middle. Like last year, about half of our revenue came from members in the tiers $0 - $1,650, and the other half came from members in tiers $3,900 - $50,000.

Open Funder Registry to transition into Research Organization Registry (ROR)

Today, we are announcing a long-term plan to deprecate the Open Funder Registry. For some time, we have understood that there is significant overlap between the Funder Registry and the Research Organization Registry (ROR), and funders and publishers have been asking us whether they should use Funder IDs or ROR IDs to identify funders. It has therefore become clear that merging the two registries will make workflows more efficient and less confusing for all concerned.
