Dat

Dat is a data distribution tool with a version control feature for tracking changes and publishing data sets. It is primarily used for data-driven science, but it can be used to keep track of changes in any data set. As a distributed revision control system it is aimed at speed, simplicity, security, and support for distributed, non-linear workflows. Dat was created by Max Ogden in 2013 to standardize the way data analysts collaborate on the changes they make to data sets. It is developed by the Dat Team through funding support from Code for Science, the John S. and James L. Knight Foundation and the Alfred P. Sloan Foundation. Dat is free software distributed under the terms of the Revised BSD license (3-clause). One of the main implementations is Beaker, a web browser that seamlessly handles dat:// URLs and allows building and seeding Dat websites. Homebase is a server-side permanent seeding tool for Dat.
