12D · Storage plan how many databases · what lives where
RARE EARTH DATA
L
Storage plan 1 database today - 4 components proposed, each with one job

1 · Core relational database - D1 (SQLite)  EXISTING DEMO

The one database that exists today. Tables fiches + liens + JSON datasets, fictitious seed only.
Free plan verified 31/10/2026: 10 databases, 500 MB each, 5 GB per account.
Proposed at scale: Postgres when concurrent writes and complex queries grow. PROPOSED

2 · Object store - R2  PROPOSED

Raw filings, PDF reports, fetch snapshots.
Immutable: one object per fetch, nothing overwritten.
Feeds the parsers; keeps the audit trail.

3 · Cache - KV  PROPOSED

API responses and ranking snapshots for fast reads.
Rebuilt after each publish; never a source of truth.

4 · Search index  PROPOSED

Full-text across companies, sites, people, publications.
Powers the unified search (company / site / deposit / permit).
Answer to "how many databases": one relational database today (D1, demo data), static JSON fallback when D1 is unavailable. Proposal adds object store, cache and search index around the same core - not more sources of truth.
12E · Table structures real schema today · proposed target model

Fallback (live today): when D1 is unavailable, the API falls back to the static JSON files.
Note · backend scope (Louis, 31 Oct)Backend tab asked by Louis: storage, data links, how many databases, data origins, structures - diagrams first. Solid borders = live in the terres-rares-data demo (Pages + Functions + one D1, fictitious seed). Dashed = proposal, nothing built, no spending decided.
Note · honesty rulesNo real data beyond the checked Lynas example (31/10/2026). No credentials, account details or internal URLs on this public board. Asian Metal licence and Postgres migration are decisions, not done.

RARE EARTH DATA
L
How we build the numbers
1 · We collect only public data: filings, government statistics, price agencies.

2 · Production, capacity and reserves are three different metrics. We never mix them. A developer with no production is ranked on capacity, clearly labelled.

3 · Every figure links to its source and fetch date. Conflicts between sources are shown, never silently averaged.

4 · Data older than its update cycle is marked stale.
Ranking principle: producers ranked on real production (confirmed). Default metric for mixed lists still open with the team.
