Is your suggestion for improvement related to a problem? Please describe.

A DOI I was searching for recently didn't work from within Jabref. 10.2143/JIABS.41.0.3285748

When I tried Crossref.org directly, it also didn't work. When I queried the publisher, they said they registered their DOIs with Medra, not Crossref, because they are a European publisher.

I find this an inadequate answer from the publisher. The whole point of DOIs is that they should be universal, not grouped in ghettos.

Describe the solution you'd like

Nevertheless, if that is how it is, could JabRef please also fallover to the Medra resolver if crossref doesn't work
