• lastUpdate - the last time this attribute value changed or was measured
• confidence - the confidence associated with this attribute value
• interval - the time period over which this attribute was sampled
• accuracyMax - the upper bound of the confidence interval associated with this attribute value
• accuracyMin - the lower bound of the confidence interval associated with this attribute value
