A ROR-some update to our API

Earlier this year, Ginny posted an exciting update on Crossref’s progress with adopting ROR, the Research Organization Registry for affiliations, announcing that we’d started the collection of ROR identifiers in our metadata input schema. 🩁 The capacity to accept ROR IDs to help reliably identify institutions is really important but the real value comes from their open availability alongside the other metadata registered with us, such as for publications like journal articles, book chapters, preprints, and for other objects such as grants.

Event Data now with added references

Event Data is our service to capture online mentions of Crossref records. We monitor data archives, Wikipedia, social media, blogs, news, and other sources. Our main focus has been on gathering data from external sources, however we know that there is a great deal of Crossref metadata that can be made available as events. Earlier this year we started adding relationship metadata, and over the last few months we have been working on bringing in citations between records.

Come and get your grant metadata!

Tl;dr: Metadata for the (currently 26,000) grants that have been registered by our funder members is now available via the REST API. This is quite a milestone in our program to include funding in Crossref infrastructure and a step forward in our mission to connect all.the.things. This post gives you all the queries you might need to satisfy your curiosity and start to see what’s possible with deeper analysis. So have the look and see what useful things you can discover.

Update on the outage of October 6, 2021

Update on the outage of October 6th. In my blog post on October 6th, I promised an update on what caused the outage and what we are doing to avoid it happening again. This is that update. Crossref hosts its services in a hybrid environment. Our original services are all hosted in a data center in Massachusetts, but we host new services with a cloud provider. We also have a few R&D systems hosted with Hetzner.

November 9 Crossref Webinar for Open Access PublishersRegister for our webinar to learn best practices for depositing metadata and ways to help with the dissemination and discoverability of OA content.

New Crossref services are being developed that have particular application to OA publishers. Did you know that our upcoming DOI Event Tracker service was inspired by a group of OASPA publishers asking if there was a way to centrally support the gathering of data that could be analyzed as altmetrics?

DOIs in Reddit

Joe Wass

In Crossref LabsEvent DataIdentifiers

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.

Oktoberfest is in full swing and that makes me think that it’s almost Frankfurt Book Fair time again!

These short (10-minute) presentations are great for anyone wanting a quick intro to what Crossref is all about. Running on Wednesday, Thursday, and Friday - at the following times each of those days:

In the next few weeks, authors with an ORCID iD will be able to have Crossref automatically push information about their published work to their ORCID record. It’s something that ORCID users have been asking for and we’re pleased to be the first to develop the integration. 230 publishers already include ORCID iDs in their metadata deposits with us, and currently there are 248,000 DOIs that include ORCID iDs.

Publishers, researchers, funders, institutions and technology providers are all interested in better understanding how scholarly research is used. Scholarly content has always been discussed by scholars outside the formal literature and by others beyond the academic community. We need a way to monitor and distribute this valuable information.

Best Practices for Depositing Funding Data

Kirsty Meddings

Kirsty Meddings – 2015 September 01

In CrossmarkResearch FundersMetadata

Crossref’s funding data initiative (FundRef) encourages publishers to deposit information about the funding sources of authors’ research as acknowledged in their papers. The funding data comprises funder name and identifier, and grant number or numbers. Funding data can be deposited on its own or with the rest of the metadata for an item of content.

DOIs and matching regular expressions

Andrew Gilmartin

Andrew Gilmartin – 2015 August 11

In IdentifiersProgramming

We regularly see developers using regular expressions to validate or scrape for DOIs. For modern Crossref DOIs the regular expression is short

/^10.\d{4,9}/[-._;()/:A-Z0-9]+$/i

For the 74.9M DOIs we have seen this matches 74.4M of them. If you need to use only one pattern then use this one.
