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
What is EAV-E?
Entity-Attribute-Value-Evidence (EAV-E) is a four-component evidence standard: Entity (which entity holds the attribute), Attribute (which property is claimed), Value (the specific claimed value), and Evidence (the corroborating source that confirms the value).
How does EAV-E extend the standard EAV model?
Standard EAV records what an entity claims about itself. EAV-E adds an explicit Evidence component, making each declaration both machine-readable and AI-citable — requiring external corroboration rather than self-assertion.
What does EAV-E compliance enable?
EAV-E compliance is required for full Tier-1 corroboration standing — it is the evidence structure that allows AI systems to treat entity attribute claims as corroborated facts rather than self-reported assertions.
