Accepted formats
Accepted formats are file formats that are accepted during deposition and are bitwise preserved for the duration of publication, but will receive no further curation on the long term. This usually is the case because file formats are not open, not properly described, or are considered obsolete. All preferred formats are accepted, as well as the following additional formats:
