RE: Timestamps and Temporal Intervals

Hi Pat,

Lets wait on temporal intervals until after the timestamps discussion is finished.

Cheers

Subject: [cti] Timestamps and Temporal Intervals

I want to help drive closure on Timestamps and breach the topic of Temporal Intervals* for the next major version.

I posit there are two distinct temporal aspects to the _expression_ of "things" and their relationships to other "things" in the CTI Domain.

(1) Absolute: "Event x" happened at absolute Time "T1".

(2) Relative Intervals: "Event x" happened "Relative To(Rn**)" "Event y" [at relative interval "Interval In"]

**Where Rn = [Before, During, After, At_Start_Of, At_End_Of, ...]

Therefore, we need to represent these temporal concepts in different forms (breaking the "One way to do Things" rule on the basis that these are two different "Things").

I believe we are very close to reaching consensus on Absolute Timestamps. I propose that we should specifically identify and treat Temporal Intervals as a separate requirement and topic for discussion somewhere in the Road Map. (IF there is consensus: perhaps as part of Relationships and/or Patterning???)

* To set the framework for what is meant by "Temporal Intervals", and some approaches one can consider in their representation, I refer everyone to James Allen's seminal paper from 1983:
