Processing Configuration
Digitized - Automated
These should be the default settings for digitized materials:
| Step | Action | Rationale |
|---|---|---|
| Scan for viruses? | No | |
| Assign UUIDs to directories | No | |
| Generate transfer structure report | No | |
| Perform file format identification (Transfer) | No | Digitized ingests contain a small set of known file formats |
| Extract packages | No | Digitized ingests should not contain packages (e.g., zip files) |
| Delete packages after extraction | Yes | |
| Perform policy checks on originals | No | Policy checks refers to MediaConch, which is only used for A/V |
| Examine contents | Skip examine contents | Runs Bulk Extractor - not necessary for digitized materials, which are already processed |
| Create SIP(s) | Create single SIP and continue processing | |
| Perform file format identification (Ingest) | No | |
| Normalize | Do not normalize | Access derivatives are created in a separate application |
| Approve normalization | Yes | |
| Choose thumbnail mode | No | |
| Perform policy checks on preservation derivatives | No | |
| Perform policy checks on access derivatives | No | |
| Bind PIDs | No | This functionality is not currently used |
| Document empty directories | No | Empty directories do not exist in RAC-created transfers |
| Reminder: add metadata if desired | Continue | Digitized ingests include a rights.csv file, so metadata does not need to be added manually |
| Transcribe SIP contents | No | This uses Tesseract to OCR TIFs; OCR workflows for digitization happen outside of Archivematica |
| Perform file format identification command (Submission documentation & metadata) | No | |
| Select compression algorithm | 7z using bzip2 | |
| Select compression level | 5 - normal compression mode | |
| Store AIP | Yes | |
| Store AIP location | Store AIP in standard Archivematica directory | |
| Upload DIP | Do not upload DIP | |
| Store DIP | Yes | |
| Store DIP location | Store DIP in standard Archivematica directory |
Digitized AV - Automated
These should be the default settings for digitized audiovisual materials:
| Step | Action | Rationale |
|---|---|---|
| Scan for viruses? | No | |
| Assign UUIDs to directories | No | |
| Generate transfer structure report | No | |
| Perform file format identification (Transfer) | No | Digitized ingests contain a small set of known file formats |

| Select compression algorithm | 7z using bzip2 | |
| Select compression level | 5 - normal compression mode | |
| Store AIP | Yes | |
| Store AIP location | Digitized AV AIP Store | Digitized AV should be stored in an S3 bucket |
| Upload DIP | Do not upload DIP | |
| Store DIP | Do not store | |
| Store DIP location | None |
Legacy Born Digital - Automated
Legacy born digital materials are those that have been recoverd from digital media items or otherwise accessioned outside of Aurora, and have been fully processed by a processing archivist before ingest into Archivematica. These should be the default settings for legacy born digital materials:
| Step | Action | Rationale |
|---|---|---|
| Scan for viruses? | No | |
| Assign UUIDs to directories | No | |
| Send transfer to quarantine | No | |
| Remove from quarantine after __ days | 28 | |
| Generate transfer structure report | No | |
| Perform file format identification (Transfer) | Yes | |
| Extract packages | No | |
| Delete packages after extraction | Yes | |
| Perform policy checks on originals | No | |
| Examine contents | Skip examine contents | |
| Create SIP(s) | Create single SIP and continue processing | |
| Perform file format identification (Ingest) | Yes | |
| Normalize | Normalize for preservation and access | |
| Approve normalization | Yes | |
| Choose thumbnail mode | No | |
| Perform policy checks on preservation derivatives | No | |
| Perform policy checks on access derivatives | No | |
| Bind PIDs | No | |
| Document empty directories | No | |
| Reminder: add metadata if desired | Continue | |
| Transcribe SIP contents | No | |
| Perform file format identification command (Submission documentation & metadata) | No | |
| Select compression algorithm | 7z using bzip2 | |
| Select compression level | 5 - normal compression mode | |
| Store AIP | Yes | |
| Store AIP location | Store AIP in standard Archivematica directory | |
| Upload DIP | Do not upload DIP | |
| Store DIP | none | |
| Store DIP location | Store DIP in standard Archivematica directory |
Born Digital
These should be the default settings for born digital materials ingested from Aurora:
| Step | Action | Rationale |
|---|---|---|
| Scan for viruses? | No | |
| Assign UUIDs to directories | Yes | |
| Generate transfer structure report | No | Since the structure of the transfer is not changed during ingest, this is not necessary |
| Perform file format identification (Transfer) | Yes | |
| Extract packages | No | |
| Delete packages after extraction | Yes | |
| Perform policy checks on originals | No | Policy checks refers to MediaConch, which is only used for A/V |
| Examine contents | Skip examine contents | Runs BulkExtractor; unclear what the benefits are of doing this at ingest |
| Create SIP(s) | Create single SIP and continue processing | |
| Perform file format identification (Ingest) | Yes | |
| Normalize | Normalize for preservation and access | |
| Approve normalization | Yes | |
| Choose thumbnail mode | No | |

FPR Customatizations
The following customizations have been added to the Format Policy Registry (the “Preservation Planning” tab):
Characterization Rules
- ffprobe and MediaInfo should be disabled for JPG and TIFF files, as ExifTool is sufficient for characterizing these formats
- ffprobe and ExifTool should be disabled for moving image files, as MediaInfo is sufficient for characterizing these formats
