A project holds a label configuration and is connected to one or multiple datasets that need to be labeled with the given label configuration.
In order to label images, a label configuration has to be defined and the images must be assigned to the project. This assignment is done within the project. There's a 1:1 relation between a project and its label configuration. However, many images can be assigned to the project through the connected datasets.
The combination of the label configuration and one image is managed as a task. These tasks are managed within the project and can be managed by the administrator.
