Crossref and DataCite are forming a working group to explore conference identifiers and project identifiers. If you are interested in joining this working group and in doing some actual work for it, please contact us at

conference identifiers WG in the subject heading.

Recently we announced that we were making some new recommendations in our DOI display guidelines. One of them was to use the secure HTTPS protocol to link Crossref DOIs, instead of the insecure HTTP.

By August 2016, Crossref will enable its members to assign Crossref DOIs to preprints. Preprint DOIs will be assigned by the Crossref member responsible for the preprint and that DOI will be different from the DOI assigned by the publisher to the accepted manuscript and version of record. Crossref’s display guidelines, tools and APIs will be modified in order to enable researchers to easily identify and link to the best available version of a document (BAV). We are doing this in order to support the changing publishing models of our members and in order to clarify the scholarly citation record.
Why is this news? Well, to understand that you need to know a little Crossref history.

Anybody who knows me or reads this blog is probably aware that I don’t exactly hold back when discussing problems with the DOI system. But just occasionally I find myself actually defending the thing…About once a year somebody suggests that we could replace existing persistent citation identifiers (e.g. DOIs) with some new technology that would fix some of the weaknesses of the current systems. Usually said person is unhappy that current systems like

On January 20th, 2015 the main DOI HTTP proxy at doi.org experienced a partial, rolling global outage. The system was never completely down, but for at least part of the subsequent 48 hours, up to 50% of DOI resolution traffic was effectively broken. This was true for almost all DOI registration agencies, including Crossref, DataCite and mEDRA.
At the time we kept people updated on what we knew via Twitter, mailing lists and our technical blog at CrossTech. We also promised that, once we’d done a thorough investigation, we’d report back. Well, we haven’t finished investigating all implications of the outage. There are both substantial technical and governance issues to investigate. But last week we provided a preliminary report to the Crossref board on the basic technical issues, and we thought we’d share that publicly now.

So have you been wondering what we’ve been doing since we posted about the experiments we were conducting using PLOS’s open source ALM code? A lot, it turns out. About a week after our post, we were contacted by a group of our members from OASPA who expressed an interest in working with the system. Apparently they were all about to conduct similar experiments using the ALM code, and they thought that it might be more efficient and interesting if they did so together using our installation. Yippee. Publishers working together. That’s what we’re all about.

So today (January 20th, 2015) the DOI HTTP resolver at dx.doi.org started to fail intermittently around the world. The doi.org domain is managed by CNRI on behalf of the International DOI Foundation. This means that the problem affected all DOI registration agencies including Crossref, DataCite, mEDRA etc. This also means that more popularly known end-user services like FigShare and Zenodo were affected. The problem has been fixed, but the fix will take some time to propagate throughout the DNS system. You can monitor the progress here:
Now for the embarrassing stuff…
