Competitions are for events where you submit work, some of the work is accepted, and your work can win awards. All of this is trackable through the Competition Record.
Exhibitions are for one-off shows (either online or in real life) where your work is being shown for a specific amount of time. When creating the Exhibition, you can choose to have us also create the Location History for the Pieces.
This way we will assign all the pieces in the Exhibition to that Location of the specific start and end dates of the Exhibition. This allows you to see what work is in the Locations (either through representation or through shows and exhibitions).
