Data Models

A hub-and-spoke family of standard data models. Open Footprint is the canonical core; supply-chain, observation, and finance standards connect at the edges as evidence in and reporting out.

The Standards Family

Implemented

Open Footprint — Standalone Data Model

The canonical hub: the polyglot environmental data model every other standard maps into.

GS1 EPCIS 2.0

Supply-chain event data: what happened, where, when, and why — as JSON-LD events that drop straight into the knowledge graph.

UN/CEFACT UNTP

Digital product passports and conformity credentials as W3C Verifiable Credentials — the regulatory-grade trust layer.

Geospatial & Observations

Sensors, satellites, and drones as standard observations: SOSA, SensorThings, STAC, and GeoSPARQL for measurement-based MRV.

FIBO & Financed Emissions

Financial-entity semantics and financed-emissions attribution: the bridge from e-liability accounting to banks and investors.

Hub-and-Spoke, Not Big-Bang

Each standard is adopted as a thin mapping at the edge of the platform, never a re-architecture. Open Footprint stays the canonical model; evidence standards feed it, reporting standards read from it, and the ontology layer keeps the semantics aligned.

Semantics behind the models

Every data element is grounded in the Sustainability Ontology and aligned to shared web ontologies.
