 * DocumentRevision, which will be valid if the Task was fetched from the database, or else null
 * (eg for Tasks which have been created but not yet saved to the database).
 *
 * fromRevision() and asMap() act as helpers to map to and from JSON - in a real application
 * something more complex like an object mapper might be used.
