The Bio-IT World Conference & Expo recently hosted the third annual Bio-IT FAIR Data Hackathon, giving experts in life sciences and IT the opportunity to FAIR-ify a range of existing data sets. Eight teams of researchers spent two days using unique identifiers, linking additional data sets, and collecting appropriate metadata, all the while adhering to the principles of FAIR—Findable, Accessible, Interoperable, Reusable—data.
