Digital Archives

Practical and historical coverage of building and organising digital document archives from scanned and born-digital files: folder and naming conventions, descriptive metadata, preservation-grade formats, integrity verification, retention, backup, and retrieval. It treats a document as a record with a lifecycle and focuses on the durable problem of finding and trusting a file years after it was stored, grounded in real preservation and records-management standards.

Planned coverage

  • Organising Scanned Documents Into an Archive — How to turn a pile of loose scans into a structured, findable archive by deciding on capture, naming, and grouping before volume grows.
  • File Naming Conventions for Document Archives — Durable, sortable naming schemes (dates in ISO order, consistent separators, avoiding fragile characters) and why the name is the cheapest form of metadata.
  • Document Metadata Explained — What descriptive, structural, and administrative metadata are, why retrieval depends on them, and how standards like Dublin Core frame the fields to record.
  • Building a Personal Document Archive — An end-to-end lifecycle workflow — capture, name, index, store, back up, retrieve — scaled down from enterprise records management to one person's files.
  • Choosing File Formats for Long-Term Archiving — Why format longevity matters and how open, well-specified formats (PDF/A, TIFF, JPEG 2000) are favoured over proprietary or lossy ones for preservation.
  • Document Retention Basics — What a retention schedule is, why keeping everything forever is itself a risk, and how deliberate disposal is part of managing an archive.
  • Backing Up a Document Archive — Applying the 3-2-1 backup principle to an archive and why an unbacked-up single copy is not really an archive.
  • Searching a Document Archive — How retrieval actually works — folder browsing, metadata filtering, and full-text search over OCR'd text — and how each depends on earlier indexing choices.
  • Finding and Removing Duplicate Documents — Why archives accumulate duplicates, how exact-copy detection via checksums differs from near-duplicate detection, and when to keep versus merge.
  • Designing Folder Structures for Archives — Trade-offs between deep hierarchies and flat structures, and designing a taxonomy that survives growth and staff turnover.
  • Tags Versus Folders for Organising Documents — The single-location constraint of folders versus the many-facets model of tags, and how the two coexist in real archives.
  • Verifying Archive Integrity With Checksums — How cryptographic hashes like SHA-256 detect silent file corruption and let you prove a stored document is unchanged.
  • Migrating a Paper Archive to Digital — Planning a bulk digitisation project — capture standards, OCR, quality control, and metadata capture — before scanning at scale.
  • Version Control for Documents — Keeping track of document revisions without a code-style VCS: naming, superseding, and recording which version is authoritative.
  • Preparing Documents for Long-Term Storage — Normalising formats, embedding metadata, bundling with checksums (BagIt-style), and documenting an archive so it remains usable decades later.
  • A History of Digital Document Archiving — How document storage moved from filing cabinets through microfilm to networked digital repositories and the retrieval problems each shift created.
  • From Microfilm to Digital Preservation — Why microfilm defined 20th-century preservation, what digitisation gained and risked, and how the field learned formats can obsolesce faster than film.
  • A History of Metadata Standards — The development of descriptive cataloguing into modern standards like Dublin Core, and why shared metadata vocabularies make archives interoperable.
  • The Origins of the OAIS Reference Model — How the Open Archival Information System model (ISO 14721) formalised what it means to preserve digital objects over the long term.
