Clarification of Event types

Distinction/Requirements:

  • Self-containing vs. Delta (does a single sample make sense?)
  • Severity of loss / ensured delivery (can samples be lost?)
  • Equidistance in time vs. spontanous occurence (are samples equidistant?)
  • History/Buffer vs. only most recent value (can I get a specific set of samples from the past?)
