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 5¼ 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.
We’ve just added to our input schema the ability to include affiliation information using ROR identifiers. Members who register content using XML can now include ROR IDs, and we’ll add the capability to our manual content registration form, participation reports, and metadata retrieval APIs in the near future. And we are inviting members to a Crossref/ROR webinar on 29th September at 3pm UTC.
We’ve been working on the Research Organization Registry (ROR) as a community initiative for the last few years. Along with the California Digital Library and DataCite, our staff has been involved in setting the strategy, planning governance and sustainability, developing technical infrastructure, hiring/loaning staff, and engaging with people in person and online. In our view, it’s the best current model of a collaborative initiative between like-minded open scholarly infrastructure (OSI) organizations.
Last year, Project Manager Maria Gould described the case for publishers adopting ROR and ROR was ranked the number one priority at our last in-person annual meeting. Now it’s time that Crossref’s services themselves took up the baton to meet the growing demand.
The inclusion of ROR in the Crossref metadata will help everyone in the scholarly ecosystem make critical connections more easily. For example, research institutions need to monitor and measure their output by the articles and other resources their researchers have produced. Journals need to know with which institutions authors are affiliated to determine eligibility for institutionally sponsored publishing agreements. Funders need to be able to discover and track the research and researchers they have supported. Academic librarians need to easily find all of the publications associated with their campus.
Earlier this month, GRID and ROR announced that after working together to seed the community-run Research Organization Registry, GRID would be retiring from public service and handing the proverbial torch over to ROR as the scholarly community’s reliable universal open identifier for affiliations. That means that our members who have been using GRID now need to consider their move to ROR and think about how they can add ROR IDs into the metadata that they manage and share through Crossref.
We’ve been able to include ROR IDs for our grant metadata schema as affiliation information for two years, since July 2019. And the Australia Research Data Commons (ARDC) was the first member to add ROR IDs to the Crossref system in 2020. In early July, we completed the work to accept ROR IDs for affiliation assertions for all other types of records with an affiliation or institution element, such as journal articles, book chapters, preprints, datasets, dissertations, and many more.
Next, we will commence the plans to support ROR in our other tools and services, such as Participation Reports. We’ll work on alignment with the Open Funder Registry and share our plans to collect the information via the new user interface we’re developing for registering and managing metadata. Open Journal Systems (OJS) already has a ROR Plugin, developed by the German National Library of Science and Technology (TIB). This supports the collection of ROR IDs and future releases of this plugin and the OJS DOI plugin will allow including ROR IDs in the metadata sent to Crossref, to support thousands of our members to share ROR IDs via their Crossref metadata.
We also aim to add ROR to our metadata retrieval options, including the REST API, which recently saw the start of an unblocking with our move to a more robust technical foundation.
The call for participation
Many Crossref publishers, funders, and service providers are already planning to integrate ROR with their systems, map their affiliation data to ROR, and include ROR in Crossref metadata. In addition to publishers and funders, libraries, repositories, and other stakeholders are developing support for ROR. For example, the Plan S Journal Checker tool uses ROR IDs to let people check whether a particular journal is compliant with an author’s funder and institutional open access policies. In addition, the ROR website shows a growing list of active and in-progress ROR integrations.
Crossref members registering research grants via Altum’s ProposalCentral system can already add ROR IDs. Now those registering articles, books, preprints, datasets, dissertations, and other research objects, can start including much clearer and all-important affiliation metadata as part of their content registration going forward. As with all newly-introduced metadata elements, we recommend adding ROR IDs from now and ongoing, but planning a distinct project to backfill older records. We know that more than 80% of records have been updated and enriched at least once with additional and cleaner metadata, so as members do this routinely, they can include ROR IDs alongside updating URLs, license or funding information, and other metadata.
