TR291B Intent Probing – Intent Extension Model v3.4.0

The requirements or constraints expressed by intent might not be needed all the time. For example a service might need to be delivered at the start date and time of the respective SLA/Contract and not earlier. Or the delivery of a service needs to stop at the end of the contract. This constitutes a time interval between the start and end times of the contract. To express that the service is only needed throughout this time interval, it could be assigned as validity condition to the intent about the service delivery. The intent temporal validity model is an intent extension model that introduces vocabulary for specifying validity conditions for requirements based on time and date.
