Normalization based on file extension is problematic, since files having manually changed extensions or no extensions can't be normalized. An alternative to normalizing based on file extension is to have the normalization path based on FITS output, preferably the DROID/PRONOM format identification. However, FITS ouptut is not always reliable. This table identifies some filetypes that DROID has trouble identifying, and shows the tool output for fileUtility and exifTool for the problem files (since if the DROID identification is wrong or missing we may fall back on fileUtility or exifTool output).
+
This table shows DROID, FileUtility and exifTool output for file extensions for which Archivematica has preservation and access plans.

This table shows DROID, FileUtility and exifTool output for file extensions for which Archivematica has preservation and access plans.

Audio AC3 (not identified) format: ATSC A/52 aka AC-3 aka Dolby Digital stream; mimetype: application/octet-stream Unknown file type
Audio AIF Name: Audio Interchange File Format; PUID: x-fmt/135; MimeType: audio/x-aiff format: IFF data, AIFF audio; mimetype: audio/x-aiff FileType: AIFF; MIMEType: audio/aiff
Audio MP3 Name: MPEG 1/2 Audio Layer 3; PUID: fmt/134; MimeType: audio/mpeg format: audio file with ID3 version 2.3.0, contains: MPEG ADTS, Layer III; mimetype: audio/mpeg FileType: MP3; MIMEType: audio/mpeg
Audio WAV Name: Waveform Audio; PUID: fmt/6; MimeType: audio/x-wav format: RIFF (little-endian) data, WAVE audio, Microsoft PCM; mimetype: audio/x-wav FileType: WAV; MIMEType: audio/x-wav
