Mission Readiness Tool

Given a fleet of UAVs, a mission planner can efficiently task platforms for missionsMission readiness can be quantified based on platform and equipment availabilitySelected platform data can be sent to operators and optimization suites

Develop missions and tasks

Expand the ontology to include civilian domain platforms

Add more detail to existing classes, more equipment properties

Develop a tool to query feasible platforms for flight craft

SPARQL queries linking the ontology to a user interface
