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.
Funders are joining Crossref to register their grants so that they can more easily and accurately track the outputs connected to the research they support.
Once you’re a member, registering grants with us means giving us information about each awarded grant, including a DOI which uniquely and persistently identifies each record. At the moment just direct XML deposit methods is supported but we’re working on a manual form to deposit and update grant metadata. This section focuses on grants, but you can also register other content types such as reports, data, and working papers.
Something to consider before you begin
Decide which grants to register first, as you get into the swing of things. For example, pilot a particular country, or area of support. It’s better to start with newly-awarded grants, and then move on to older or long-running awards - these are cheaper to register, and are more likely to have produced research papers, so they’re great for demonstrating the full potential of connected research metadata.
Constructing your identifiers (DOIs)
A DOI is made up of a DOI resolver, a prefix, and a suffix. When you join Crossref as a member, we give you a DOI prefix. You combine this with a suffix of your choice to create a DOI. Although some funders choose to use their internal grant identifier as the DOI suffix, we advise you to make your suffix opaque, meaning that it does not encode or describe any information about the work. Your DOI becomes active once it is successfully registered with us.
Grant landing pages
Your grant metadata records should link to a landing page where you can find information about the grant. Examples: https://doi.org/10.37717/220020589, https://doi.org/10.35802/107769. Should a grant move to a new landing page, the URL in the grant’s metadata is updated to point to the new location. There’s no charge to update metadata for existing deposits.
Formatting grant metadata for registration
Grants can be registered for all sorts of support provided to a research group or individual, such as awards, use of facilities, sponsorship, training, or salary awards.
Here’s the section of our schema for grant metadata. If you’re working with a third-party system, such as Proposal Central or EuroPMC, they may be able to help with this piece of work.
You may be able to map your own data and identifiers to our schema. See our example deposit file - this is a full example, and many of the fields it contains are optional, but we encourage you to provide as much information as you can. Rich metadata helps maximum reuse of the grant records you register with Crossref. This .xsd file helps explain what goes into each field, and the parameters (length, format) of what is accepted in each field. Here’s a less techy version.
When you’ve created your XML files, use our checker to test them - this will show any potential errors with your files. For help with resolving problems, send your XML file and the error message to Support.
Uploading your files to Crossref
Once you’re happy with your files, upload them to us using the admin tool, or submit them through HTTPS POST.
Once your submission is successful, your grant DOIs are ‘live’ and ready to be used. It’s good practice to add the grant DOI to the landing page for the grant, as in this example for https://doi.org/10.37717/220020589:
Spread the word about your grant identifiers
Let your grant submission systems, awardees, and other parties know you are supporting Crossref grant identifiers, and that they should start collecting these identifiers too. Crossref grant metadata (including grant DOIs) is made openly available through our APIs, so it can be used by third parties (including publishers, grant tracking systems) to link grants to related research outputs.
