Understanding Entity-Attribute-Value-Evidence (EAV-E)
A four-component evidence standard for machine-readable entity claims: Entity (which entity holds the attribute), Attribute (which property is being claimed), Value (the specific claimed value), and Evidence (the corroborating source that confirms the value). EAV-E extends the standard EAV data model by requiring explicit evidence for every claim — making each declaration both machine-readable and AI-citable. EAV-E compliance is required for full Tier-1 corroboration standing.

Frequently Asked Questions
How does EAV-E extend the standard EAV data model?
Standard EAV (Entity-Attribute-Value) structures machine-readable claims but does not require evidence. EAV-E adds the Evidence component — a corroborating source that confirms the claimed value — making each declaration both machine-readable and independently verifiable by AI systems.
Why is the Evidence component necessary for Tier-1 corroboration standing?
AI systems weight evidence-backed claims more heavily than unsupported declarations. Without explicit corroborating sources co-located with each claim, structured data is treated as self-asserted — reducing its contribution to AI citation confidence.
Does every attribute require separate evidence, or can one source cover multiple claims?
Ideally each attribute has its own dedicated evidence source. A single source covering multiple claims produces corroboration dependency — if that source becomes unavailable or is discredited, multiple claims lose their evidence simultaneously.
