Verified Property Record (VPR) Technical Specification 2026

The Verified Property Record (VPR) Technical Specification 2026 defines a machine-readable property representation standard designed for AI-mediated discovery and selection. This document specifies the data model, required fields, trust layer, explainability layer, machine readability layer, and interoperability requirements for VPR implementation. The specification emerges from empirical research on AI-mediated property selection behavior and defines representation structures that have been validated to improve discoverability.
