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.
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 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.
Looking at the road ahead, we’ve set some ambitious goals for ourselves and continue to see new members join from around the world, now numbering 16,000. To help achieve all that we plan in the years to come, we’ve grown our teams quite a bit over the last couple of years, and we are happy to welcome Carlos, Evans, Fabienne, Mike, Panos, and Patrick.
Content Registration allows members to register and update metadata via machine or human interfaces.
When you join Crossref as a member you are issued a DOI prefix. You combine this with a suffix of your choice to create a DOI, which becomes active once registered with Crossref. Content Registration allows members to register a DOI and deposit or update its associated metadata, via machine or human interfaces.
Benefits of content registration
Academic and professional research travels further if it’s linked to the millions of other published papers. Crossref members register content with us to let the world know it exists, instead of creating thousands of bilateral agreements.
Members send information called metadata to us. Metadata includes fields like dates, titles, authors, affiliations, funders, and online location. Each metadata record includes a persistent identifier called a digital object identifier (DOI) that stays with the work even if it moves websites. Though the DOI doesn’t change, its associated metadata is kept up-to-date by the owner of the record.
Richer metadata makes content useful and easier to find. Through Crossref, members are distributing their metadata downstream, making it available to numerous systems and organizations that together help credit and cite the work, report impact of funding, track outcomes and activity, and more.
Members maintain and update metadata long-term, telling us if content moves to a new website, and they include more information as time goes on. This means that there is a growing chance that content is found, cited, linked to, included in assessment, and used by other researchers.
Participation Reports give a clear picture for anyone to see the metadata Crossref has. See for yourself where the gaps are, and what our members could improve upon. Understand best practice through seeing what others are doing, and learn how to level-up.
This is Crossref infrastructure. You can’t see infrastructure, yet research—and researchers all over the world—rely on it.
Dissertations: includes single dissertations and theses, but not collections.
Grants: grants include both direct funding, and other types of financial support, such as the use of equipment and facilities. Registering a grant includes assigning it a DOI (or grant ID), which can be referenced in all resulting research activities, linking funding with outputs.
Your content registration fees are billed quarterly in arrears. This means you’ll usually receive a bill at the beginning of each quarter for the content you registered in the previous quarter. The only exception is if you’ve only registered a small number of DOIs.
