This is a production-focused resource for building, automating, and auditing archival digitization and digital preservation systems. It is written for archivists, digital preservation specialists, cultural heritage technology teams, and the Python automation engineers who keep ingest pipelines running.

Every guide treats a batch of scanned materials the way the OAIS reference model does — as a Submission Information Package that must be validated, fixity-checked, and logged before it becomes a trustworthy Archival Information Package. You will find concrete, runnable patterns for batch scanning coordination, metadata extraction (EXIF/IPTC/XMP), format normalization (PDF/A, TIFF), checksum validation, preservation-action logging, and compliance reporting.
