57 release sources, every licence documented

Every value in Apex traces to one of the sources below: public regulators, research bodies, manufacturer press, and structured knowledge graphs. The current immutable release includes 57commercial-use-cleared sources. Reviewed registry definitions that are inactive or not delivered by this release are not mixed into the list below. Attribution requirements are honoured on the row that uses each delivered source.

Source attribution is per-row, not per-dataset. Every cell ships with its own source and source_url. When a single variant's CO₂ comes from EEA and its HP comes from a manufacturer press release, both citations travel with the row. See /docs/provenance.
Registry and release counts have different grains. The registry contains 116 reviewed definitions, including inactive and non-delivered candidates. 78 currently have active provenance. This page lists only the 57 sources included in the current dated release, with their factual metadata and rights flags.

Each source also has a dedicated landing page with licence summary, fields contributed, and variant count. Browse the sources hub →

silver tier

9 sources

silver · corroborated / structured

Corroborated or structured-but-non-primary sources. Community knowledge graphs and encyclopaedic infoboxes score PCAF DQ 3; manufacturer press (factual specifications only) scores DQ 2, as the OEM is the primary source for its own published specs.

derived tier

11 sources

derived · apex-computed, labelled per row

Values Apex computes from other attributed sources — unit conversions, regressions, engine-family and PCAF estimation. Each derived value carries its own provenance row recording the exact derivation; it is never presented as primary.
