Event and Time Series ontologyEvent and Time Series Ontology

Container for a set of values. The four kinds of value set are: data points, data collections, events and time series.

• Is Element Of ^op
• Has Quality ^op
• Has Temporal Context ^op
• Identifier ^dp
• Name ^dp
• Creation Time ^dp

• Event ^c
• Data Collection ^c
• Time Series ^c
• Data Point ^c

An occurrence of a change in the environement that happens at a specific time.

• Has Data Value ^op
• Cause ^dp
• State ^dp
• Triggering Time ^dp

• Cause ^dp some
  
• State ^dp some
  
• Triggering Time ^dp max 1
  

A data collection represents a set of data points, that share some common context. Data Collections may also have a common collection time.

• Comprises ^op
• Collection Values Count ^dp
• Collection Time ^dp

Value container for a time series. Time series elements can be regularly spaced (in time) with a fixed step.

• is Composed Of ^op
• Has Step ^op
• Series Elements Count ^dp

A data point with a unique value, and possible data time.

• Belongs To ^op
• Has Data Value ^op
• Data Time ^dp
• Rank ^dp

• Data Time ^dp max 1
  
• Rank ^dp max 1
  

A property value is the value associated with a unique property and a unit of measurement.

• Has Data Value ^op
• Has Data Value ^op

• Value ^dp max 1
  
• ets:hasUnit max 1
  

the relationship designating the time series in which the value set is element. A value set can be part of multiple time series.

the relationship indicating the value sets composing a time series.

the relationship indicating the data collection to which the data point belongs.

the relationship indicating data points comprised in a data collection.

The step between two elements of a time series. This value is only indicated for regular series.

The relationship indicating a quality value for a value set.

The relationship indicating a property value for a data point.

The relationship indicating a property value for an event.

Associates a temporal context for value set coverage. This represents the timeseries entire coverage interval, a data point or an event validity time, i.e time period in which collected values still valid.

The data time indicating the value recording time.

The rank of a data point within a data collection if r

The count of collection data points.

The collection time indicating common data points values recording time.

The cause that triggered an event.

The state of a system following the occurence of an event.

Trigerring time refers to the timestamp when the event occurs in the real world.

The count of timeSeries elements.

The identifier of a value set .

the name of a value set .

Creation time refers to the timestamp when the value set is created.

The value associated with a property value .

the relationship indicating the data collection to which the data point belongs.

The relationship indicating a property value for a data point.

The relationship indicating a property value for an event.
