• Create a ResolvedTitle model that holds: titlepattern fk, candidateurl fk, resolution_status (resolved, unresolved), resolution_date_time, resolved_title, error_type (make a choice field out of the list of errors), error_string, http_status_code (when the candidate URL was accessed by requests etc)
• ListView of the resolved title model? Write a view on the frontend that can show this to Emily.
