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.
Interested? This is the kickoff a series of case studies on the innovative and interesting things people are doing with the Metadata API. Welcome to Part 1.

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.
We’ve released a new version of Chronograph. This post explains how it was put together. One for the programmers out there.

****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 a piece 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:
Beyond the DOI
For Crossref, a DOI is just one of several types of metadata we register, albeit an important one.

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:

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.
This information is interesting because it shows not only where DOI hyperlinks are found across the web, but also when they are actually followed. This data allows us a glimpse into scholarly citation beyond references in traditional literature.
