Answer:
A work of art intended to document is going to provide evidence that an event occurred.
A work of art intended to commemorate is going to call something to remembrance and serve as a memorial.
A work of art can both document and commemorate something. For example, statues generally do so by showing realistically what type of person someone was and to serve as a memorial of their sacrifices.
A piece of art intended for documentation is a historical, factual account of a person, place, or event. A piece of art intended for commemoration is also a documentation, however its main purpose is to serve as a form of remembrance, or a memorial, rather than a historical documentation. Sometimes as time passes, historical events and/or people become increasingly appreciated by current cultures and/or generations, and therefore a piece that was originally a documentation, can become a memorial or visual remembrance as well.
