Research Integrity Roundtable 2024

For the third year in a row, Crossref hosted a roundtable on research integrity prior to the Frankfurt book fair. This year the event looked at Crossmark, our tool to display retractions and other post-publication updates to readers. Since the start of 2024, we have been carrying out a consultation on Crossmark, gathering feedback and input from a range of members. The roundtable discussion was a chance to check and refine some of the conclusions we’ve come to, and gather more suggestions on the way forward.

How good is your matching?

In our previous blog post in this series, we explained why no metadata matching strategy can return perfect results. Thankfully, however, this does not mean that it’s impossible to know anything about the quality of matching. Indeed, we can (and should!) measure how close (or far) we are from achieving perfection with our matching. Read on to learn how this can be done! How about we start with a quiz? Imagine a database of scholarly metadata that needs to be enriched with identifiers, such as ORCIDs or ROR IDs.

Update on the Resourcing Crossref for Future Sustainability research

We’re in year two of the Resourcing Crossref for Future Sustainability (RCFS) research. This report provides an update on progress to date, specifically on research we’ve conducted to better understand the impact of our fees and possible changes. Crossref is in a good financial position with our current fees, which haven’t increased in 20 years. This project is seeking to future-proof our fees by: Making fees more equitable Simplifying our complex fee schedule Rebalancing revenue sources In order to review all aspects of our fees, we’ve planned five projects to look into specific aspects of our current fees that may need to change to achieve the goals above.

Meet the candidates and vote in our 2024 Board elections

On behalf of the Nominating Committee, I’m pleased to share the slate of candidates for the 2024 board election. Each year we do an open call for board interest. This year, the Nominating Committee received 53 submissions from members worldwide to fill four open board seats. We maintain a balanced board of 8 large member seats and 8 small member seats. Size is determined based on the organization’s membership tier (small members fall in the $0-$1,650 tiers and large members in the $3,900 - $50,000 tiers).

Warnings, Caveats and Weasel Words

Most of the experiments linked to here are running on R&D equipment in a non-production environment. They may disappear without warning and/or perform erratically. If one of them isn’t working for some reason, come back later and try again.

InChI Lookup

2 minute read.

Note: This experiment has been retired. This description has been kept for reference, but many of the links and/or services that appear below no longer work.

The idea is to create a mechanism that would allow Crossref publishers to record InChIs in their submitted Crossref metadata. This, in turn, would allow us to provide a service that would allow users to:

Lookup the published articles that mention a particular InChI.
Lookup the InChIs mentioned in a published article.

Similar services could, conceivably, be provided for other types of semantic metadata.

The following is a demonstrator of what an DOI2InChI lookup service might look like. Please note that the XML representation of the results is very basic and is not best-practice for linked-data.

The demonstrator currently only holds DOIs and InChIs for a few publishers. A summary of the contents of the database can be found on the status page

http://inchi.crossref.org/status

A list of all the Crossref DOIs that contain InChIs can be seen here:

http://inchi.crossref.org/dois

A list of all the InChIs that have been registered with Crossref can be seen here:

http://inchi.crossref.org/inchis

The system provides the following API calls:

Return all the DOIs that have been registered with a given InChI

http://inchi.crossref.org/dois/InChI=1S/C4H6O2/c1-3-6-4(2)5/h3H,1H2,2H3

Return all the InChIs that have been registered for a given DOI
