Open Standards

JSON Schema, REST API, semantic versioning. Built on proven technologies that minimise integration costs and avoid vendor lock-in.

Trust Through Provenance

Know who said what, when, with evidence. Every data element carries provenance metadata for verifiable trust.

Not a platform

PDTF is a governance framework. Apps can be different, networks can vary, but everyone follows the same rules.

Consumer centric

Property owners control their data. They decide who can see what.

Market proof

No vendor lock-in, no permanent gatekeepers, no platform dominance.
