DOIs in Reddit

Skimming the headlines on Hacker News yesterday morning, I noticed something exciting. A dump of all the submissions to Reddit since 2006. “How many of those are DOIs?”, I thought. Reddit is a very broad community, but has some very interesting parts, including some great science communication. How much are DOIs used in Reddit?

(There has since been a discussion about this blog post on Hacker News)

We have a whole strategy for DOI Event Tracking, but nothing beats a quick hack or is more irresistible than a data dump.

Many Metrics. Such Data. Wow.

[ Crossref Labs loves to be the last to jump on an internet trend, so what better than than to combine the Doge meme with altmetrics? Note: The API calls below have been superceeded with the development of the Event Data project. See the latest API documentation for equivalent functionality Want to know how many times a Crossref DOI is cited by the Wikipedia? Or how many times one has been mentioned in Europe PubMed Central?

DOIs unambiguously and persistently identify published, trustworthy, citable online scholarly literature. Right?

The South Park movie , “Bigger, Longer & Uncut” has a DOI: a) So does the pornographic movie, “Young Sex Crazed Nurses”: b) And the following DOI points to a fake article on a “Google-Based Alien Detector”: c) And the following DOI refers to an infamous fake article on literary theory: d) This scholarly article discusses the entirely fictitious Australian “Drop Bear”: e)

If you’ve ever thought that scholarly citation practice was antediluvian and perverse- you should check-out patents some day. Over the past year of so Crossref has been working with Cambia and the The Lens to explore how we can better link scholarly literature to and from the patent literature. The first object of our collaboration was to attempt to link patents hosted on the new, beta version of The Lens to the Scholarly literature.

Crossref and DataCite unify support for HTTP content negotiation

Last year Crossref and DataCite announced support for HTTP content negotiation for DOI names. Today, we are pleased to report further collaboration on the topic. We think it is very important that the two largest DOI Registration Agencies work together in order to provide metadata services to DOI names. The current implementation is documented in detail at The documentation explains HTTP content negotiation as implemented by both Registration Agencies and provides a list of supported content types.

DataCite supporting content negotiation

In April In April for its DOIs. At the time I cheekily called-out DataCite to start supporting content negotiation as well. Edward Zukowski (DataCite’s resident propellor-head) took up the challenge with gusto and, as of September 22nd DataCite has also been supporting content negotiation for its DOIs. This means that one million more DOIs are now linked-data friendly. Congratulations to Ed and the rest of the team at DataCite. We hope this is a trend.

Content Negotiation for Crossref DOIs

So does anybody remember the posting DOIs and Linked Data: Some Concrete Proposals? Well, we went with option “D.” From now on, DOIs, expressed as HTTP URIs, can be used with content-negotiation. Let’s get straight to the point. If you have curl installed, you can start playing with content-negotiation and Crossref DOIs right away: curl -D - -L -H “Accept: application/rdf+xml” “”  curl -D - -L -H “Accept: text/turtle” “http://dx.

DOIs and Linked Data: Some Concrete Proposals

Since last month’s threads (here, here, here and here) talking about the issues involved in making the DOI a first-class identifier for linked data applications, I’ve had the chance to actually sit down with some of the thread’s participants (Tony Hammond, Leigh Dodds, Norman Paskin) and we’ve been able sketch-out some possible scenarios for migrating the DOI into a linked data world. I think that several of us were struck by how little actually needs to be done in order to fully address virtually all of the concerns that the linked data community has expressed about DOIs.

A Christmas Reading List… with DOIs

Was outraged (outraged, I tell you) that one of my favorite online comics, PhD, didn’t include DOIs in their recent bibliography of Christmas-related citations.. So I’ve compiled them below. We care about these things so that you don’t have to. Bet you will sleep better at night knowing this. Or perhaps not… A Christmas Reading List… with DOIs. Citation: Biggs, R, Douglas, A, Macfarlane, R, Dacie, J, Pitney, W, Merskey, C & O’Brien, J, 1952, ‘Christmas Disease’, BMJ, vol.
