Ontologies

This is a starting page for the description of the ontology network used in the SemIoT Platform.

Concepts

• Actuator (san:Actuator)
• Sensor (ssn:Sensor)
• Property (ssn:Property)
• Feature Of Interest (ssn:FeatureOfInterest)
• State (semiot:State)
  • a device can be only in one state in any particular moment
  • only two states are supported: "Powered On" and "Powered Off"
• Operation (semiot:Operation)
  • some process which a device performs
  • at any moment a device performs an Operation or is in "Powered Off" state
  • There are several operation types (aka sub classes of semiot:Operation)
    • Actuation Operation
    • Sensing Operation
    • etc.
  • может иметь параметры. Пример: (а) уровень яркости свечения лампочки; (б) перекачивание воды насосом со скоростью N; (в) охлаждение/нагрев кондиционером до температуры N.
• Execution Plan/Workflow
  • продолжительная процедура
  • прописывает последовательный переход устройства из одного состояния в другое
  • например: программа стирки в стиральной машине
