Notice of amendments to Crossref membership terms and bylaws

In its March 2025 meeting, the Crossref board unanimously voted to update both the Crossref bylaws and the Crossref membership terms to:

  • Provide more clarity and alignment between our bylaws and membership terms, where they had become out of sync over the years.

  • Reflect previous board motions and bring both documents up-to-date with current processes for suspending and revoking membership, and reviewing those decisions.

  • Work towards being more explicit about what “Member Practices” should look like in terms of preserving the integrity of the scholarly record.

Metadata Advisory Group call for applications

We’ve been accelerating our metadata development efforts and recently released version 5.4 of our metadata schema, and are planning to release version 5.5 (including support for multiple contributor roles and the CRediT taxonomy) this summer. We will also extend our grants schema based on the Funders Advisory Group work, and make progress on other changes as set out on our new metadata development roadmap.

As we work towards the vision of the rich and reusable open network of relationships connecting research organizations, people, things, and actions, dubbed the Research Nexus, our schemas need to change to accommodate the evolving landscape of research processes and communications.

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.turing.library.northwestern.edu/status

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

http://inchi.crossref.org.turing.library.northwestern.edu/dois

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

http://inchi.crossref.org.turing.library.northwestern.edu/inchis

The system provides the following API calls:

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

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