Ontology Specification

Abstract

This module extends the trajecto ontology with universal contextual dimensions applicable across different movement domains.

Introduction back to ToC

Source: https://github.com/sotirisAng/trajecto-stakg/blob/main/ontology/modules/context.ttl. The whole ontology is documented from http://w3id.org/trajecto (the core module), which imports every module.
