Methodology

Foodatron organizes food data into a connected knowledge graph. This page documents our sourcing, normalization, and comparison rules. Full details are maintained in the repository at docs/methodology.md.

Core principles

• Every observed value is traceable to a cited source.
• Comparisons state and consistently apply a serving basis.
• Missing values are shown as unavailable, never as zero.
• Calculated values are reproducible from stored source data.
• We do not fabricate nutrition, price, or ingredient data.
