One last note! While we’re on the topic of cats and metadata, I wholeheartedly suggest following @HistoricalCats on Twitter. It’s an bot that tweets cat-related metadata records harvested by the Digital Public Library of America from various digital collections. Cute historic photos abound, though occasionally the “cat” keyword turns up some less-than-happy cats-in-science materials. Check out the DPLA’s application profile, a derivative of the Europeana Data Model.
