The base object is the task, of which a person can be a part.
Each task has a uniquely-identifying label and a not-necessarily-unique description.
Each task can have a parent task which can be changed or removed (in which case it becomes top-level).
Relationships between tasks and people are based on tasks' labels.
You can use the commands below to construct, manipulate and display your tasks and the list of people who work on them.
