RE: [ws-calendar] Is there a difference?

That is my sense, Bill, but I am trying to make sure.

For this conversation, assume UTC, leaving out DST and related issues. I’m looking for whether there should be a deeper meaning when applied to services. For people, if a CalConnect meeting starts at 12:00 and goes for an hour, one could argue that since they always start at 12:05, this means that it is scheduled until 1:05….

For services, I am interested in what is the required / expected state of the service at 3:01.

Let’s say I schedule a room for 78 degrees between 2-3.

Let’s say I schedule the same room for 72 degrees between 3-4.

Let’s say that I know it takes 10 minutes to go between the temperatures.

If the first schedule is in response to DR for Energy, then I am committed to not setting the thermostat *until* 3:00

If the second schedule is in response to CEO arriving for a meeting, then I am committed to getting the room temperature down *by* 3:00

I think that "support" and "the profile says use this" are two different things.

I would suggest listing only A and B, and preferably only one (profiling as well as extending) so there's a consistent representation.

I see no real difference between A and B.

Allowing the higher expessivity is fine for human calendars as the interpretation is done by calendar software. For the energy/building uses, a single canonical representation is appropriate.

Thanks!

What’s the difference in *actions*, and in *performance* between

Do X beginning at 2:00 for an hour duration

Do X beginning at 2:00 for and ending at 3:00

Do X for an hour ending at 3:00

All are possible using the VTODO data structure.

One (C) is not allowed if I understand correctly

Within any interaction, it would be simpler, cleaner to allow only (A) or (B)

Do we need to allow both?

Does B have a finite stop and A does not?

Why would we support both?
