The main kinds of things (or Sources) that Voltaire keeps track of are Contacts, Artists, Artworks, and Jobs.

A Job is something that can you do with an Artwork, such as shipping the Artwork, or selling the Artwork.

A Transaction is a special kind of a Job that affects an Artwork's State (described in the next section). Transactions are represented in the Sources listbox with a medium blue folder icon.

Jobs that are not Transaction do not affect Artwork State. Jobs are represented in the Sources listbox with a light blue folder icon.
