# SkyRwa Flight-to-Asset Ontology
# ============================================================================
# Title:   SkyRwa — A Knowledge Graph Ontology for UAM Flight Data Assets
# Version: 1.0.0
# Date:    2026-07-23
# Purpose: Provides a formal vocabulary for the flight-to-asset pipeline
#          in Urban Air Mobility systems.  Covers evidence, governance,
#          productization, valuation, and settlement.
# Persistent namespace (pending w3id registration, see w3id-submission.md):
