The first annual Endangered Data Week will be held from April 17-21, 2017. As noted on the DLF Endangered Data Week wiki page, “Endangered Data Week is a national series of independently-organized events intended to raise awareness of threats to publicly available data, discuss the power dynamics of data creation, sharing, and retention, and work to make endangered data more accessible and secure.”
