To properly archive and give access to a file in Apollo, we need to know what format it is, for example "PDF", "HTML", or "OpenDocument format". In order to facilitate preservation of the deposited content stored in Apollo we need to ascertain that the content is stored in file formats that are either open or well-known and described. Below you will find a list of formats all recommended by the Apollo repository team. The list is not exhaustive; please email support@repository.cam.ac.uk  if you have content you wish to deposit in other formats.
