Registry

Public record registry

Every record on this site is registered here under a persistent identifier. A registry entry means the record has passed validation, its location has been generalised to a safe precision, and the published files have been audited for leaked coordinates. Registered 26 records, generated 2026-09-20.

Identifier scheme

Identifiers take the form CTF-<VAULT>-<six digits>, for example CTF-END-000031. The prefix CTF is fixed. VAULT is one of PAL, END, EDA, LIN, INT, ICO and must match the record vault. The six-digit serial is assigned once and never reused; a withdrawn record keeps its identifier and is listed as withdrawn rather than deleted.

Each entry carries a version: the first twelve characters of a SHA-256 hash of the built record. It changes only when the record's published content changes, so a citation can name the version it relied on.

Cite a record using its preferred citation and identifier, for example: Chronos Terra Foundation (2026). Pinewood podzol profile, Abernethy. CTF-EDA-000001.

Machine-readable exports

  • registry.json: this registry with the scheme and every entry.
  • registry.csv: the same entries as a spreadsheet-friendly table.
  • records.json: the full built records (public geometry, media, links), and /generated/records/<identifier>.json for one record.
  • ctf-taxa.csv: the taxon-level export exchanged with sister programmes such as the Eco-Memory Registry.

Exports contain no true coordinates. Generalised and withheld records appear with their precision class only.
