We've written about the project, called Operation War Diary, before. In honor of Veteran's Day, however, we thought we'd re-highlight it. As a refresher, here's the ultimate goal: If enough people tag enough pages, it will form a searchable database. Then, if someone is interested in a named person in the diaries, he or she can see all the mentions of that person across the British army in just one click. What if someone is interested in the proportion of time an average WWI British soldier spent resting versus patrolling versus digging trenches? With enough tags and access to the database, anybody could calculate that. You could start asking "big data" questions about some decidedly pre-digital documents. Pretty cool.
