Tags

In Supervisely tags provide an option to associate some additional information with the labeled image or the labels on it. Each individual tag can be attached to a single image or asingle annotation only once, but there's not limit on how many times the same tag can be attached to different parts of the scene. There are different lists of tags for images and figures in the annotation file.

When defining a tag, you assign it a name, possible values for a tag instance and what types of things it can be attached to. We support values of the following types: None (without an assigned value), Text, Number, and One of.
