In essence, they provide a way of adding Python dictionaries to an image, a project or a dataset - and a Python dictionary is fit for data of virtually any form. Here are a few ways of interacting with data in this form through Python."

The goal is to make sure that the tags used in the data are consistent across groups. This will make it easier to search for data and to use the data in the future.
