We believe in Persistent Identifiers. We believe in defence in depth. Today we’re excited to announce an upgrade to our data resilience strategy.
Defence in depth means layers of security and resilience, and that means layers of backups. For some years now, our last line of defence has been a reliable, tried-and-tested technology. One that’s been around for a while. Yes, I’m talking about the humble 5ÂĽ inch floppy disk.
Recording data citations supports data reuse and aids research integrity and reproducibility. Crossref makes it easy for our members to submit data citations to support the scholarly record.
TL;DR Citations are essential/core metadata that all members should submit for all articles, conference proceedings, preprints, and books. Submitting data citations to Crossref has long been possible. And it’s easy, you just need to:
Include data citations in the references section as you would for any other citation Include a DOI or other persistent identifier for the data if it is available - just as you would for any other citation Submit the references to Crossref through the content registration process as you would for any other record And your data citations will flow through all the normal processes that Crossref applies to citations.
At Crossref, we care a lot about the completeness and quality of metadata. Gathering robust metadata from across the global network of scholarly communication is essential for effective co-creation of the research nexus and making the inner workings of academia traceable and transparent. We invest time in community initiatives such as Metadata 20/20 and Better Together webinars. We encourage members to take time to look up their participation reports, and our team can support you if you’re looking to understand and improve any aspects of metadata coverage of your content.
What’s in the metadata matters because it is So.Heavily.Used.
You might be tired of hearing me say it but that doesn’t make it any less true. Our open APIs now see over 1 billion queries per month. The metadata is ingested, displayed and redistributed by a vast, global array of systems and services that in whole or in part are often designed to point users to relevant content. It’s also heavily used by researchers, who author the content that is described in the metadata they analyze.
The quickest way to test whether your DOI and its associated metadata have been registered successfully (and your DOI is now active) is to enter your DOI link (DOI displayed as a link, such as https://doi-org.turing.library.northwestern.edu/10.13003/5jchdy) into a browser window, and check if it resolves correctly.
If your DOI doesn’t resolve successfully, read on for more information about the process your submission goes through, why there might be a delay, and which messages you’ll receive depending on your submission method.
If you register your content using the web deposit form, your submission is sent to a submission queue. You’ll see a “success” message in the web deposit form confirming that your submission has been successfully sent to our submission queue, but this doesn’t mean that your registration is complete.
As your submission is processed in the queue, we send you two messages:
XML record email, subject line: Crossref WebDeposit - XML. This email includes the XML created by the web deposit form. Do keep this information, as it may be useful in the future. Receiving this email is a confirmation that your file has been received for processing, and entered into our submission queue.
submission log email, subject line: Crossref Submission ID. This email is sent once your XML has made it through the queue, includes your submission ID, tells you if your deposit has been successful, and provides the reason for any failure.
If your submission log email tells you that your submission was successful, your DOI is now live and active (or your update to metadata for an existing DOI has worked).
If your submission failed, please address the errors flagged in the confirmation, and resubmit. Learn more about error messages.
If you don’t receive your submission log email immediately, it’s probably because your submission is still in the queue. It can stay in the queue between several minutes and several hours depending on how large your submission file is, and how busy our submission queue is at that time. Learn more about how to view the submission queue.
If you don’t receive your submission log email and you can’t see your submission in the queue, it may be that your access to register content has been suspended due to unpaid invoices. If this is the case, please contact us.
Verify your registration - grant deposit form
The grant registration form registers your record in real time, with no queueing or delay. If your submission has been successful, you’ll see a “success” message, which means your DOI is now live and active or your update to an existing DOI has worked.
Your “success” message will also contain a submission ID. If you need to, you can log into our admin tool using your account credentials and use this submission to view your deposit.
If your submission hasn’t been successful, you’ll see an error message explaining the problem.
Verify your registration - if you’re still using the deprecated Metadata Manager
The Metadata Manager tool is in beta and contains many bugs. It’s being deprecated at the end of 2021. We recommend using the web deposit tool as an alternative, or the OJS plugin if your content is hosted on the OJS platform from PKP.
If you’re still using Metadata Manager, here’s how to verify your registration.
Unlike other content registration methods, Metadata Manager registers content in real-time - with no queueing of content. If your submission has been successful, you’ll see a “success” message, which means that your DOI is now live and active (or your update to metadata for an existing DOI has worked).
Your “success” message will also contain a submission ID. If you need to, you can log in to our admin tool using your account credentials and use this submission ID to view your deposit.
If your submission hasn’t been successful, you’ll see a warning symbol - click on this to see the error message explaining the problem.
Verify your registration - direct deposit of XML using our admin tool
Submissions using our admin tool are sent to a submission queue. Once your submission has been accepted into the queue we display a SUCCESS - Your batch submission was successfully received message. This means that your deposit has been submitted to our processing queue, but it has not yet been processed.
Registration of your content only occurs after your submission has worked its way through the queue, when you will receive an email with the subject line Crossref Submission ID, which includes your submission ID, tells you if your deposit has been successful, and provides the reason for any failure.
If your deposit has been successful, then your new DOI is live and active (or your update to metadata for an existing DOI has worked).
If your submission failed, please address the errors flagged in the email, and resubmit. Not sure what the error messages mean and what you need to do? Learn more about error messages.
If you don’t receive your submission log email immediately, it’s probably because your submission is still in the queue. It can stay in the queue between several minutes and several hours depending on how large your submission file is, and how busy our submission queue is at that time. Learn more about how to view the submission queue.
If you don’t receive your submission log email and you can’t see your submission in the queue, it may be that your access to register content has been suspended due to unpaid invoices. If this is the case, please contact us.
Verify your registration - XML deposit using HTTPS POST
Most items registered with us are submitted via HTTPS POST. When files are POSTed to our system, you’ll receive a 200 status message to confirm that we’ve received it. Your files are then added to a submission queue to await processing, and once your submission has been processed, you’ll receive a submission log (either by email or through the notification callback service if you have that enabled).
If your submission log shows a success, then your DOI is live and active (or your update to metadata for an existing DOI has worked).
If your submission log shows a failure, please address the errors flagged in the email, and resubmit. Not sure what the error messages mean and what you need to do? Learn more about error messages.
There may be a delay between your submission being received by the queue and completing processing. It can stay in the queue between several minutes and several hours depending on how large your submission file is, and how busy our submission queue is at that time. Learn more about how to view the submission queue.
Verify your registration - Crossref XML plugin for OJS
If you are using the Crossref XML plugin for OJS to send your submission to us directly, check the status of your deposit by clicking the Articles tab at the top of the plugin settings page.
