Editorial interest 84/100 Selection signal · not a rating of the site

P3DF is an evolving open standard for packaging building geometry, asset relationships, navigation data, and recorded observations for digital twins and AI agents.

Landing page captured for the 2026-09-05 issue.

Field notes

A draft .p3df package is organized as a ZIP container with a manifest, scene relationships, GLB geometry, navigation data, and telemetry or history in Arrow or Parquet. The site demonstrates the concept with an account-free Creator preview and an illustrative workflow in which a permissioned camera observation helps an agent locate a book. Its proposed MCP layer would expose spaces, assets, observations, and telemetry through authenticated, permission-scoped queries.
