The release of the 2025 Leiden Ranking marks an series of critical steps towards a more open research information system.

It is great to see the Open Edition placed side by side with the traditional version of Ranking. Debates continue on the qualities and risks of moving to fully open research information systems. Putting the evidence together is key to having an informed conversation.

But perhaps more exciting for me is the opportunity it illustrates to expand the Ranking and make it more inclusive.

My main criticism of the Leiden Ranking methodology has always been that it excludes non-English and diverse outputs that don't fit into the definition of "core" journals.

Now we can see how that inclusion shifts the picture. And as always the work and the data from the @cwts shows the highest standards of technical quality and transparency.

This is a great step forward and demonstration of what can be done with Open Research Information
