Very important notice for academic cybersecurity. Could CrossRef made bulk doi validation tools as browser plugins, VSIX, etc., for pdfs, webpages, etc? They could apply the DOI format rules to all DOI-like links and perhaps even pre-validate DOIs before the user (human or bot) clicks on them.
Fake DOI-like strings are increasingly common. Learn how to check whether a DOI is valid, how prefixes work, and more. https://tinyurl.com/599yk8yv

Open funder metadata is essential for true research transparency - Impact of Social Sciences
Funder metadata is vital to understanding where research comes from & how it is used. But, to be truly effective it needs to be open to all.

Scientific open infrastructure is the invisible backbone of research. It’s what connects scientists across disciplines + borders, builds essential skills, sparks collaboration, and preserves knowledge for future discovery.
