Taking the “con” out of conferences

TL;DR

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 community@crossref.org and include the text conference identifiers WG in the subject heading.

Using the Crossref REST API. Part 3 (with SHARE)

As a follow-up to our blog posts on the Crossref REST API we talked to SHARE about the work they’re doing, and how they’re employing the Crossref metadata as a piece of the puzzle.  Cynthia Hudson-Vitale from SHARE explains in more detail…

URLs and DOIs: a complicated relationship

As the linking hub for scholarly content, it’s our job to tame URLs and put in their place something better. Why? Most URLs suffer from link rot and can be created, deleted or changed at any time. And that’s a problem if you’re trying to cite them.

The Organization Identifier Project: a way forward

The scholarly communications sector has built and adopted a series of open identifier and metadata infrastructure systems to great success.  Content identifiers (through Crossref and DataCite) and contributor identifiers (through ORCID) have become foundational infrastructure to the industry.  

New Crossref DOI display guidelines are on the way

TL;DR

Crossref will be updating its DOI Display Guidelines within the next couple of weeks.  This is a big deal.  We last made a change in 2011 so it’s not something that happens often or that we take lightly.  In short, the changes are to drop “dx” from DOI links and to use “https:” rather than “http:”.  An example of the new best practice in displaying a Crossref DOI link is: https://doi.org/10.1629/22161

Announcing PIDapalooza - a festival of identifiers

The buzz is building around PIDapalooza - the first open festival of scholarly research persistent identifiers (PID), to be held at the Radisson Blu Saga Hotel Reykjavikon November 9-10, 2016. PIDapalooza will bring together creators and users of PIDs from around the world to shape the future PID landscape through the development of tools and services for the research community. PIDs support proper attribution and credit, promote collaboration and reuse, enable reproducibility of findings, foster faster and more efficient progress, and facilitate effective sharing, dissemination, and linking of scholarly works.

DOI-like strings and fake DOIs

TL;DR Crossref discourages our members from using DOI-like strings or fake DOIs. Details Recently we have seen quite a bit of debate around the use of so-called “fake-DOIs.” We have also been quoted as saying that we discourage the use of “fake DOIs” or “DOI-like strings”. This post outlines some of the cases in which we’ve seen fake DOIs used and why we recommend against doing so. Using DOI-like strings as internal identifiers Some of our members use DOI-like strings as internal identifiers for their manuscript tracking systems.

Linked Clinical Trials initiative gathers momentum

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. If you look at this article in The Lancet and click on the Crossmark button you will see that in the Clinical Trials section there are links to three other articles reporting on the same trial: two from the American Heart Journal and one from BMJ’s Heart.

Where do DOI clicks come from?

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.

Getting Started with Crossref DOIs, courtesy of Scholastica

I had a great chat with Danielle Padula of Scholastica, a journals _platform with an integrated peer-review process that was founded in 2011. We talked about how journals get started with Crossref, and she turned our conversation into a blog post that describes the steps to begin registering content and depositing metadata with us. Since the result is a really useful description of our new member on-boarding process, I want to share it with you here as well.
