Schema-First Metadata Ingestion

Normalize external metadata into stable typed records before building reports, graphs or drift logic.

Evidence tierPROJECTOfficial sources0Other sources0Last verifiedNot recorded

Evidence tier describes my hands-on relationship with the content. Official sources describe platform contracts/documentation. Production observations should not automatically be treated as official limits.

Problem

Vendor/API payloads change shape, casing and nesting; direct reporting on raw JSON spreads fragility everywhere.

Approach

Preserve raw payloads, map them into a canonical contract, flag unknown fields and keep adapters at the ingestion boundary.

Tradeoffs

Adapter maintenance

Canonical models can lag new upstream features

Downstream logic becomes much easier to test

Connected knowledge

Keep following the context.

Explicit and inferred relationships from the Atlas model.

Metadata Snapshot & Drift Review

Normalize two environment exports, compare stable object fingerprints and review dependency drift before a migration or structural change.
