Architectural concept of a home whose digital twin could be provided to its owner at handover

Every building should come with a digital twin.

Owners should receive an open, portable digital record of their building, alongside its plans and legal documents, for use with compatible systems of their choice.

Evolving open standard

AI-generated architectural concept

An open standard for digital twins and AI agents.

P3DF (Portable 3D Format) combines spatial and operational information for robotics, smart homes and building management. The specification is evolving. Its public release will use Apache License 2.0.

Spatial geometry

Building layouts, spatial bounds and 3D models.

Asset relationships

Objects, locations and semantic relationships.

Navigation

Routes, access conditions and clearance constraints.

Recorded state

Time-series data linked to assets and spaces.

Portable files. Connected cloud data.

An exported P3DF is a point-in-time reference. The proposed cloud platform connects camera observations, time series and spatial information.

A point-in-time reference

A .p3df package carries the scene, its relationships and embedded data. Share it, archive it, or hand it to another tool without requiring a connection to the original service.

Locate an object using spatial and recorded data.

A home robot could use a P3DF twin to identify the book’s last recorded location and plan a search.

An illustrative agent workflow. Camera integrations and live cloud context are in development. P3DF supplies context; the robot supplies perception, planning and action.

Query digital twins from Claude and ChatGPT.

The proposed Model Context Protocol (MCP) interface will let AI agents retrieve spatial information, locate assets and query recorded observations and telemetry.

Designed to work with existing standards.

The draft uses GLB, Arrow and Parquet. Proposed bridges to IFC, OpenUSD and AAS will preserve existing domain models. These bridges are not yet certified.

Review interoperability

CIFR invites robotics, smart-home and building technology teams to contribute implementations and technical review.

Frequently asked questions

Created by the Council for Independent Frontier Research, a non-profit organisation. Formal standardization is a future objective.

What is P3DF?

P3DF (Portable 3D Format) is an evolving open standard for digital twins in the AI agentic age. It combines spatial geometry, asset relationships, navigation and recorded telemetry in a portable package. The upcoming public release will use Apache License 2.0.

How will Claude and ChatGPT interact with P3DF?

A proposed Model Context Protocol (MCP) integration will expose digital-twin queries to Claude, ChatGPT and other MCP clients. Proposed operations include finding assets, retrieving observations and querying telemetry. No public P3DF MCP server or verified client integration is available yet.

Is P3DF a file or a cloud database?

An exported .p3df file is a point-in-time reference. The proposed cloud platform uses the same spatial model as a database linking camera observations, time series and spatial information. Live cloud services and camera integrations are in development.

How does P3DF relate to existing standards?

P3DF is designed to complement existing standards. The draft uses GLB, Arrow and Parquet. Bridges to IFC, OpenUSD and Asset Administration Shell (AAS) are proposed and have not been certified.

What is available now?

The architecture overview and illustrative Creator browser preview are available. Native Creator apps, example .p3df packages and the public Apache-2.0 repository are coming soon. P3DF is evolving and has not been formally adopted by a standards body.
