Taxonomy of aggregations ?

Extracted and adapted from saref-portal#6 (closed)

regarding Max, Min, Skewness, StandardDeviation, etc., they are underspecified and I'd recommend decoupling them from properties, defining a separate codelist for those kinds of aggregations, and adding a property saref:hasAggregationKind to link a property or observation to those kinds.

A proposal is available in a separate ontology https://w3id.org/coswot/core/aggregation

An initial list could be:

• Maximum
• Minimum
• Skewness
• StandardDeviation
• Mean
• Median
• NumberOfSignChanges
• NumberOfTimesAboveThreshold (which would require an additional property to specify the threshold)
• etc.
