Answer: Documentation is largely related in sense to commemoration. Documentation refers to the recording of data, events or any kind of information in a specific period of time. In the case of commemoration, only important events undergone by an important person are honored. Documentation is largely for recording purposes without the regards of what's important or not.
A work of art intended for documentation is always an historical and factual account of a person, place or event. Documentation provide evidence that an event occurred, thus a work of art intended for documentation provide evidence for events in history. A work of art intended for commemoration serves principally as a memorial or a mean to remember a thing, person or an event. It stands as a form of remembrance rather than mean of documentation.
