At Crossref and ROR, we develop and run processes that match metadata at scale, creating relationships between millions of entities in the scholarly record. Over the last few years, we’ve spent a lot of time diving into details about metadata matching strategies, evaluation, and integration. It is quite possibly our favourite thing to talk and write about! But sometimes it is good to step back and look at the problem from a wider perspective. In this blog, the first one in a series about metadata matching, we will cover the very basics of matching: what it is, how we do it, and why we devote so much effort to this problem.

This year’s public data file is now available, featuring over 156 million metadata records deposited with Crossref through the end of April 2024 from over 19,000 members. A full breakdown of Crossref metadata statistics is available here.

Like last year, you can download all of these records in one go via Academic Torrents or directly from Amazon S3 via the “requester pays” method.

Download the file: The torrent download can be initiated here. Instructions for downloading via the “requester pays” method, along with other tips for using these files, can be found on the “Tips for working with Crossref public data files and Plus snapshots” page.

Earlier this year, we reported on the roundtable discussion event that we had organised in Frankfurt on the heels of the Frankfurt Book Fair 2023. This event was the second in the series of roundtable events that we are holding with our community to hear from you how we can all work together to preserve the integrity of the scholarly record - you can read more about insights from these events and about ISR in this series of blogs.

Crossref is undertaking a large program, dubbed 'RCFS' (Resourcing Crossref for Future Sustainability) that will initially tackle five specific issues with our fees. We haven’t increased any of our fees in nearly two decades, and while we’re still okay financially and do not have a revenue growth goal, we do have inclusion and simplification goals. This report from Research Consulting helped to narrow down the five priority projects for 2024-2025 around these three core goals:

The Crossref Nominating Committee is inviting expressions of interest to join the Board of Directors of Crossref for the term starting in January 2025. The committee will gather responses from those interested and create the slate of candidates that our membership will vote on in an election in September.

Expressions of interest will be due Monday, May 27th, 2024

This is an exciting time to join the board, as we have a number of active projects underway: We are considering resourcing Crossref for a sustainable future and board members will be part of deciding any changes to our fees scheme and overseeing its implementation. We’re focusing on how our community and metadata can contribute to ensuring the integrity of the scholarly record. We’re broadening our metadata record to capture richer funding and institutional affiliations. We’re working towards a future where the scholarly record prioritizes relationships between research outputs to build a holistic research nexus. The board helps guide this work.

This past year has been a captivating journey of immersion within the Crossref community, a mix of online interactions and meaningful in-person experiences. From the engaging Sustainability Research and Innovation Conference in Port Elizabeth, South Africa, to the impactful webinars conducted globally, this has been more than just a professional endeavour; it has been a personal exploration of collaboration, insights, and a shared commitment to pushing the boundaries of scholarly communication.

One of the challenges that we face in Labs and Research at Crossref is that, as we prototype various tools, we need the community to be able to test them. Often, this involves asking for deposit to a different endpoint or changing the way that a platform works to incorporate a prototype.

The problem is that our community is hugely varied in its technical capacity and level of ability when it comes to modifying their platform. Some mega-publishers, for instance, outsource their platforms and so are dependent on third party developers/organizations when they want to make a change. Many smaller publishers, by contrast, use systems such as OJS, which come with Crossref plugins that make life very easy… but that require hard code changes to accommodate prototypes. Such changes are way beyond the technical capacity of most journal editors.

When each line of code is written it is surrounded by a sea of context: who in the community this is for, what problem we’re trying to solve, what technical assumptions we’re making, what we already tried but didn’t work, how much coffee we’ve had today. All of these have an effect on the software we write.

By the time the next person looks at that code, some of that context will have evaporated. There may be helpful code comments, tests, and specifications to explain how it should behave. But they don’t explain the path not taken, and why we didn’t take it. Or those occasions where the facts changed, so we changed our mind.

To this end, I wrote a basic application, credcheck, that will allow you to test a Crossref credential against an API.

Subject classifications have been available via the REST API for many years but have not been complete or reliable from the start and will soon be deprecated. dfdfd

The subject metadata element was born out of a Labs experiment intended to enrich the metadata returned via Crossref Metadata Search with All Subject Journal Classification codes from Scopus. This feature was developed when the REST API was still fairly new, and we now recognize that the initial implementation worked its way into the service prematurely.
