No open science without open metadata

Metadata conveys the provenance, evidence, results of, and responses to research. This once-geeky afterthought has become one of the most important tools in progressing the open science movement and the growing attention on open metadata rightly reflects the growing urgency for open science. But opening up metadata doesn’t just happen; multiple ‘nudges’ have taken place over the years, both coordinated and transparent, as well as uncoordinated and behind closed doors. Learning from prior initiatives and actions, we will cover some ideas for what it may take to speed up open metadata for open science, and what infrastructure organisations like Crossref are doing and can do to support the effort.
