Did you know that we have a shiny, not so new, API kicking around? If you missed Geoffrey’s post in 2014 (or don’t want a Cyndi Lauper song stuck in your head all day), the short explanation is that the Crossref Metadata API exposes the information that publishers provide Crossref when they register their content with us. And it’s not just the bibliographic metadata either-funding and licensing information, full-text links (useful for text-mining), ORCID iDs and update information (via Crossmark)-are all available, if included in the publishers’ metadata.

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.

TL;DR

Crossref discourages our members from using DOI-like strings or fake DOIs.

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.

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:

1. The owner of the content would like to be formally cited if the content is used in a scholarly context.
2. The owner of the content considers that it is worthy of being made persistent.

Beyond the DOI

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.

You can read about the latest results from this analysis in the “Where do DOI Clicks Come From” blog post.

Having this data tells us, amongst other things:

• where people are using DOIs in unexpected places
• where people are using DOIs in unexpected ways
• where we knew people were using DOIs but the links are more popular than we realised

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.

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.  As always, comments and questions are welcome here, at member@Crossref.org, and @CrossrefOrg.  - Anna_

Back in 2014, Geoffrey Bilder blogged about the kick-off of an initiative between Crossref and Wikimedia to better integrate scholarly literature into the world’s largest knowledge space, Wikipedia. Since then, Crossref has been working to coordinate activities with Wikimedia: Joe Wass has worked with them to create a live stream of content being cited in Wikipedia; and we’re including Wikipedia in Event Data, a new service to launch later this year. In that time, we’ve also seen Wikipedia importance grow in terms of the volume of DOI referrals.

TL;DR:

We will proceed with implementing the proposed support for registering content before online availability. Adopting the workflow will be optional and will involve no extra fees.

Background

At the end of January, Crossref issued a “request for community comment” on a proposed new process to support the registration of content including DOIs before online availability. We promised that we would summarize the results of the survey once we had received and analyzed all the responses.

Crossref is proposing a process to support the registration of content—including DOIs and other metadata—prior to that content being made available, or published, online. We’ve drafted a paper providing background on the reasons we want to support this and highlighting the use cases. One of the main needs is in journal publishing to support registration of Accepted Manuscripts immediately on or shortly after acceptance, and dealing with press embargoes.
