How do artist in residence programs tend to work? For example, what tend to be the responsibilities of the artist, and what are those of the organization offering an artist in residence program?

Isn't the duration of time typically a year?

Is there promotion that's involved?

What might be the nature of the projects in which the artist engages? I would think that some aspect of the projects would need to benefit the organization.

Is there usually some sort of contract, or can it be sort of a written understanding?

I've been wondering about initiating such a program, so having a better understanding of those that exist would be very helpful.
