Label Id Description
Result Result [The Result of an Observation, Actuation, or act of Sampling. To store an observation's simple result value one can use the hasSimpleResult property.]
Thing Thing
Detection Limit DetectionLimit [An observed value for which the probability of falsely claiming the absence of a component in a material is beta, given a probability alpha of falsely claiming its presence.]
System Property SystemProperty [An identifiable and observable characteristic that represents the System's ability to operate its primary purpose: a Sensor to make Observations, an Actuator to make Actuations, or a Sampler to make Samplings.]
Observable Property ObservableProperty [An observable quality (property, characteristic) of a FeatureOfInterest.]
Property Property [A quality of an entity. An aspect of an entity that is intrinsic to and cannot exist without the entity.]
Operating Property OperatingProperty [An identifiable characteristic that represents how the System operates under the specified Conditions. May describe power ranges, power sources, standard configurations, attachments and the like.]
Drift Drift [As a Sensor Property: a continuous or incremental change in the reported values of Observations over time for an unchanging Property under the defined Conditions. As an Actuator Property: a continuous or incremental change in the true value of the acted on ActuatableProperty over time for an unchanging command under the defined Conditions.]
Operating Range OperatingRange [Describes normal OperatingProperties of a System under some specified Conditions. For example, to the power requirement or maintenance schedule of a System under a specified temperature range. In the absence of OperatingProperties, it simply describes the Conditions in which a System is expected to operate. The System continues to operate as defined using SystemCapability. If, however, the SurvivalRange is violated, the System is 'damaged' and SystemCapability specifications may no longer hold.]
Resolution Resolution [As a Sensor Property: the smallest difference in the value of a ObservableProperty being observed that would result in perceptably different values of Observation Results, under the defined Conditions. As an Actuator Property: the smallest difference in the value of an Actuation command that would result in a value change of the ActuatableProperty being acted on, under the defined Conditions.]
Procedure Procedure [A workflow, protocol, plan, algorithm, or computational method specifying how to make an Observation, create a Sample, or make a change to the state of the world (via an Actuator). A Procedure is re-usable, and might be involved in many Observations, Samplings, or Actuations. It explains the steps to be carried out to arrive at reproducible results.]
Maintenance Schedule MaintenanceSchedule [Schedule of maintenance for a System in the specified Conditions.]
Survival Range SurvivalRange [Describes SurvivalProperties of a System under some specified Conditions. For example, the lifetime of a System under a specified temperature range. In the absence of SurvivalProperties, simply describes the Conditions a System can be exposed to without damage. For example, the temperature range a System can withstand before being considered damaged. The System continues to operate as defined using SystemCapability. If, however, the SurvivalRange is violated, the System is 'damaged' and SystemCapability specifications may no longer hold.]
Actuator Actuator [A device that is used by, or implements, an (Actuation) Procedure that changes the state of the world.]
System System [System is a unit of abstraction for pieces of infrastructure that implement Procedures. A System may have components, its subsystems, which are other systems.]
Actuatable Property ActuatableProperty [An actuatable quality (property, characteristic) of a FeatureOfInterest.]
Agent Agent
Sampler Sampler [A device that is used by, or implements, a Sampling Procedure to create or transform one or more samples.]
Condition Condition [Used to specify ranges for qualities that act as conditions on a system/sensor's operation. For example, wind speed of 10-60m/s may be used as the condition on a SystemProperty, for example, to state that a sensor has a particular accuracy in that condition.]
Actuation Range ActuationRange [The set of values that the Actuator can return as the Result of an Actuation under the defined Conditions with the defined system properties.]
