An export is, at its core, an array of assets. Each asset, in turn, contains metadata about itself, plus an object representing the labeling task that was exported.

Each task, in turn, other than metadata about the task itself such as its review status, also contains the actual object annotation data, such as X and Y coordinates of a bounding box, answers to classification questions, relations, and more.

Our export format was created with the main goal of being easy to convert from. Our philosophy is to provide the user with the most control possible over their annotations.

By design, our export format is a malleable one, built to be easy to parse and understand at a first glance, so that you can get to converting it to whatever format you need as quickly as possible.
