Preservation Maturity Self-Assessment (human-entered)

A Guide for Repository Administrators


What is the maturity self-assessment?

The Preservation Maturity Self-Assessment is where your institution rates its own digital-preservation practice, section by section, against a recognised international maturity model, records the ratings with evidence notes, and tracks how the profile changes over time.

It lives at Admin -> Preservation maturity self-assessment (/admin/preservation-self-assessment) and is available to administrators only.

It complements the computed Preservation Maturity dashboard (/admin/preservation-maturity). The two are deliberately different things:

Surface What it is Where the numbers come from
Computed maturity dashboard A read-only score the platform derives automatically Concrete records in this instance (checksums, formats, events, ...)
Maturity self-assessment (this) A human, organisational rating you enter Your own judgement, section by section, with evidence

A mature programme uses both: the computed dashboard is an honest mirror of what the system can evidence, while the self-assessment captures organisational realities (policy, legal basis, staffing, strategy) that no automated probe can see.


The maturity models

Two widely used, jurisdiction-neutral models are supported (no country assumptions are made; both are international).

NDSA Levels of Digital Preservation

Five functional areas, each self-rated on a 0 (not yet) to 4 scale:

  1. Storage - multiple copies with geographic and provider diversity
  2. Integrity (fixity) - checksums recorded, verified on a cadence, content protected
  3. Control (security) - who can read or change content is restricted and logged
  4. Metadata - descriptive, administrative, technical and preservation (PREMIS) metadata
  5. Content (file formats) - format identification (PRONOM/PUID), diversity, obsolescence monitoring

DPC Rapid Assessment Model (DPC RAM)

Eleven sections (three organisational, eight service-capability), each rated 0 to 4:

  • Organisational viability
  • Policy and strategy
  • Legal basis
  • IT capability
  • Continuous improvement
  • Acquisition, transfer and ingest
  • Bitstream preservation
  • Content preservation
  • Metadata management
  • Discovery and access
  • Reuse

The 0 to 4 maturity scale

The shared scale labels are: 0 Minimal awareness, 1 Awareness, 2 Basic, 3 Managed, 4 Optimised. These labels (and the list of models) come from the Dropdown Manager (groups assessment_model and maturity_level), so an administrator can rename or extend them under Admin -> Dropdowns without touching code.


Running an assessment

  1. Open Admin -> Preservation maturity self-assessment.
  2. In Start a new assessment, choose the model (NDSA or DPC RAM), optionally give it a title, an assessor and a date, then Begin assessment.
  3. On the rating form, for each section pick the level that best describes your practice. Each level shows a short descriptor so you know what it means. Add an Evidence / notes entry to record the justification.
  4. Save draft to keep working, or Save and mark complete when finished.
  5. You land on the maturity profile - a radar of section levels plus horizontal bars and your overall (average) maturity.

The profile and progress over time

  • The profile page shows one assessment as a CSS radar and per-section bars, with each section's evidence note and the overall average maturity.
  • The landing page lists every past assessment and draws a small trend per model, so you can see whether your maturity is improving release over release.
  • Export JSON downloads a self-contained snapshot of an assessment (model, metadata, every section with its level, label and evidence, plus the overall average) for reporting, sharing with funders, or feeding into a wider dashboard.

Notes

  • The self-assessment is entirely separate from your records: it only ever writes to its own two tables and never changes a catalogue description.
  • It is admin-only and resilient - a fresh or mid-migration install shows a calm "being set up" state rather than an error.
  • The models are seeded as data; the level descriptors are taken from the published NDSA Levels v2.0 and the DPC Rapid Assessment Model.
