We now have linked clinical trials deposits coming in from five publishers: BioMedCentral, BMJ, Elsevier, National Institute for Health Research and PLOS. It’s still a relatively small pool of metadata - around 4000 DOIs with associated clinical trial numbers - but we’re delighted to see that “threads” of publications are already starting to form.

Known unknowns If you follow this blog, you are going to notice a theme over the coming months- Crossref supports the deposit and distribution of a lot more kinds of metadata than people usually realise.

The act of registering a DOI (Digital Object Identifier) for scholarly content is sometimes conflated with the notion of conferring a seal of approval or other mark of good quality upon an item of content.  This is a fundamental misunderstanding. A DOI is a tool, not a badge of honor.

Last week a bunch of Crossref’s staff traveled to the 2016 Society for Scholarly Publishing Annual Meeting in Vancouver, BC.  After we returned en masse, all nine of us put our heads together to share some of our personal memories of the event.

This is a joint blog post with Dario Taraborelli, coming from WikiCite 2016. In 2014 we were taking our first steps along the path that would lead us to Crossref Event Data. At this time I started looking into the DOI resolution logs to see if we could get any interesting information out of them. This project, which became Chronograph, showed which domains were driving traffic to Crossref DOIs.

As part of our Event Data work we’ve been investigating where DOI resolutions come from. A resolution could be someone clicking a DOI hyperlink, or a search engine spider gathering data or a publisher’s system performing its duties. Our server logs tell us every time a DOI was resolved and, if it was by someone using a web browser, which website they were on when they clicked the DOI. This is called a referral.

It’s here. After years of hard work and with a huge cast of characters involved, I am delighted to announce that you will now be able to instantly link to all published articles related to an individual clinical trial through the Crossmark dialogue box. Linked Clinical Trials are here!

TL;DR 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.

It can be a pain when companies rebrand as it usually requires some coordinated updating of wording and logos on websites, handouts, and slides. Nevermind changing habits and remembering to use the new names verbally in presentations. Why bother? As our infrastructure and services expanded, we sometimes branded services with no reference to Crossref.

I had a great chat with Danielle Padula of Scholastica, a journals platform with an integrated peer-review process that was founded in 2011.

Test out the early preview of Event Data while we continue to develop it. Share your thoughts. And be warned: we may break a few eggs from time to time! Want to discover which research works are being shared, liked and commented on? What about the number of times a scholarly item is referenced? Starting today, you can whet your appetite with an early preview of the forthcoming Crossref Event Data service.
