The following is a guest post by Bob Mesibov. The first Darwin Core Million closed on 31 March with no winner. Since I'm seeing better datasets this year in my auditing work for Pensoft, I've decided to run the competition every six months. Missed the first Darwin Core Million and don't know what it's about? Don't get too excited by the word "million". It refers to the number of data items in a Darwin Core occurrences table, not to the prize!
