Standards & interoperability

Built to outlive us, and to play well with others.

An archive locked in a proprietary box is a slow-motion data loss. These are the commitments that keep records portable, citable, and machine-legible — by people and by the systems that increasingly read on their behalf.

The commitments

Stable identifiers
Every record has a permalink that does not change when its title or copy is edited. A link you cite today resolves to the same record later.
Citable by design
Each record exports a citation in three formats scholars actually paste: Chicago (note form), BibTeX (@misc), and RIS.
Plain licensing
Reuse terms are expressed against well-understood bases - Creative Commons CC BY-NC for the open archive, all rights reserved for the rest - not bespoke legalese only we understand.
Machine-readable
Records carry structured metadata; the catalog is exposed via sitemap and a machine-readable feed, and discovery crawlers — including AI agents — are welcomed rather than walled out.
Open formats out
What you license, you receive in standard image formats — no viewer lock-in, no format you'll be unable to open in a decade.

Descriptive crosswalk

Our internal descriptive fields map onto widely-used cultural-heritage metadata conventions; the formal crosswalk (field-by-field) is published here as it's finalised, so other archives can ingest our records cleanly. Fill in
