We primarily focus on expressivity and computational aspects, discussing issues such as duration, superposition, conflicts, attempts, discharge, and complexity, while identifying semantic choices which arise and the challenges these pose for full monitoring of legal contracts.engDeontic LogicTimed LogicNormative SystemsLegal ContractsMonitoringText
