Timeline framework for time-state analytics

A method, comprising:

• receiving a stream of raw data values of an attribute recorded at discrete points in time, wherein each received raw data value of the attribute is associated with a timestamp;
• converting the received stream of raw data values into a timeline representation of the attribute over time, wherein the timeline representation comprises a sequence of spans, wherein a span comprises a span start time, a span end time, and a span value, and wherein the span value comprises an encoding of one or more values of the attribute over a time interval determined by the span start time and the span end time, and wherein when a change in value of the attribute is detected from the stream of raw data values, a current span is closed and a new span is generated;
• and
• determining a time-state metric according to a timeline request configuration, wherein the timeline request configuration comprises one or more timeline operations, and wherein the time-state metric is computed at least in part by performing a timeline operation on the timeline representation of the attribute.

A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:

• receiving a stream of raw data values of an attribute recorded at discrete points in time, wherein each received raw data value of the attribute is associated with a timestamp;
• converting the received stream of raw data values into a timeline representation of the attribute over time, wherein the timeline representation comprises a sequence of spans, wherein a span comprises a span start time, a span end time, and a span value, and wherein the span value comprises an encoding of one or more values of the attribute over a time interval determined by the span start time and the span end time, and wherein when a change in value of the attribute is detected from the stream of raw data values, a current span is closed and a new span is generated;
• and
• determining a time-state metric according to a timeline request configuration, wherein the timeline request configuration comprises one or more timeline operations, and wherein the time-state metric is computed at least in part by performing a timeline operation on the timeline representation of the attribute.
