“Once we’ve exhausted our exploration of the data, we see no reason not to make them available publicly,” she said in a news release accompanying the data. “The benefits are numerous, from inspiring high school students to the training of the particle physicists of tomorrow. And personally, as CMS’s data preservation coordinator, this is a crucial part of ensuring the long-term availability of our research data.”
