Hell’s teeth. So today (January 20th, 2015) the DOI HTTP resolver at dx.doi.org started to fail intermittently around the world. The doi.org domain is managed by CNRI on behalf of the International DOI Foundation. This means that the problem affected all DOI registration agencies including Crossref, DataCite, mEDRA etc.

tl;dr http://chronograph.labs.crossref.org At Crossref we mint DOIs for publications and send them out into the world, but we like to hear how they’re getting on out there.

Do you want to see if a Crossref DOI (typically assigned to publications) refers to DataCite DOIs (typically assigned to data)? Here you go: https://web.archive.org/web/20150121025249/http://api.labs.crossref.org/graph/doi/10.4319/lo.1997.42.1.0001 Conversely, do you want to see if a DataCite DOI refers to Crossref DOIs?

Remember when I said that the Wikipedia was the 8th largest referrer of DOI links to published research? This despite only a fraction of eligible references in the free encyclopaedia using DOIs. We aim to fix that.

You can now easily search for publications and add them to your ORCID profile in the new beta of Crossref Metadata Search (CRMDS). The user interface is pretty self-explanatory, but if you want to read about it before trying it, here is a summary of how it works.

We have just released a bunch of new functionality for Crossref Metadata Search.

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.

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.
