Concepts¶

Task: Is an assignment for a small piece of work. A Team Manager or Admin creates Tasks with information about the Task Type, the referenced dataset, starting positions, and advanced options. These tasks will be distributed to eligible users.
Task Instance: Some Tasks need to be completed redundantly by multiple users to assure quality. The single assignments of the tasks are called Instances.
Task Type: Contains a blueprint for Tasks. Includes metadata, such as a description with instructions, allowed annotation modes, and advanced options.
Project: A group of many related Tasks is called a Project. Projects have a priority assigned to them which affects the order of assignment to users. Projects may be paused and resumed to manage the user workloads and priorities.
Experience: Admins and Team Managers can assign experience levels to users. Experiences are defined by a domain and a value, such as flight-annotation and 100. Tasks specify the required experience level of a user.

It is possible to download all annotations that belong to either a Project or a Task Type for further processing.
