Using AWS S3 as a large key-value store for Chronograph

One of the cool things about working in Crossref Labs is that interesting experiments come up from time to time. One experiment, entitled “what happens if you plot DOI referral domains on a chart?” turned into the Chronograph project. In case you missed it, Chronograph analyses our DOI resolution logs and shows how many times each DOI link was resolved per month, and also how many times a given domain referred traffic to DOI links per day.

A fairer approach to waiting for deposits

If you ever see me in the checkout line at some store do not ever get in the line I’m in. It is always the absolute slowest. Crossref’s metadata system has a sort of checkout line, when members send in their data they got processed essentially in a first come first served basis. It’s called the deposit queue. We had controls to prevent anyone from monopolizing the queue and ways to jump forward in the queue but our primary goal was to give everyone a fair shot at getting processed as soon as possible.

2016 upcoming events - we’re out and about!

Check out the events below where Crossref will attend or present in 2016. We have been busy over the past few months, and we have more planned for the rest of year. If we will be at a place near you, please come see us (and support these organizations and events)!

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.

Outreach Day DC. Next Up? You Tell Us

Rallying the community is a key Crossref role. Sometimes this means collaborating on new initiatives but it is also an ongoing process, a cornerstone of our outreach efforts. Part of rallying the community is bringing people together, literally, in a series of outreach days around the globe. It means we encourage dialog with us and among members and non-publisher affiliates. We want to hear from the community and we hope to facilitate conversations in it.

Hello preprints, what’s your story?

The role of preprints Crossref provides infrastructure services and therefore we support scholarly communications as it evolves over time. Today, preprints are increasingly discussed as a valuable part of the research story (beyond physics, math, and a small set of sub-disciplines). Preprints might play a positive role in catalyzing research discovery, establishing priority of discoveries and ideas, facilitating career advancement, and improving the culture of communication within the scholarly community.

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.

Distributing references via Crossref

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. We are in the process of completely revamping our web site, help documentation, and marketing to better promote our metadata distribution capabilities, but in the mean time we think it would be useful highlight one of our most under-promoted functions- the ability to distribute references via Crossref.

Beyond the DOI to richer metadata

In DOIsMetadata

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. The presence of a Crossref DOI on content sends a signal that: The owner of the content would like to be formally cited if the content is used in a scholarly context.

Our memories of #SSP2016

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. Crossref’s Rosa and Susan at the Fun Walk/Run sponsored by High Wire. 5K before breakfast! On Cybersecurity and the Scholarly World —“The session described the many and complicated security threats that IT systems face and how threat detection and defense is a constantly ongoing activity.
