Don't take it from us: Funder metadata matters - Crossref

"Though collectively, this research paints a fairly dim picture of the current availability, completeness and accuracy of existing funding information in publication metadata, all is not lost. This is a good opportunity to point out the value and availability of grant records since unique, persistent identifiers for grants (yes, DOIs for grants) paired with more and better funding metadata from publishers go a very long way to realizing the vision of the Research Nexus. And it certainly would make things a whole lot easier for the researchers who use this open metadata to analyze the scholarly record for the rest of us."
