TerraFabric
TerraFabric Ontology · v1.0.0

A complete semantic model of the EO marketplace

55 classes and 70 properties across six modules — from sensors and processing levels to licences, quotes, spending mandates and C2 tasking. Aligned to SOSA/SSN, DCAT 3, PROV-O, GeoSPARQL, ODRL and schema.org, so any agent that speaks the web's vocabularies already speaks TerraFabric.
