access to readable, explorable, local data is a profoundly unmet need in our communities

Time is hard enough

problems we're trying to solve

volunteered information

let's work together

#0 Nothing worth computing happened before Jan 1 1970

data on a plane

time component

#1 the tools you work with should take care of that for you

yes, tools CAN handle time

we must be intentional in how we use them

#2 to add time to geographic data, just add a time field or column

1932-01-01T00:00:00

1932-12-12T00:00:00

#2.50 <aside> Timelines move from left to right.

Do you know your birthday?

#3 Time is precise yeah?

once collected, your time-enabled data will have a uniform level of precision

CHRONON

#4 Events in time are instantanious

Beginnings and endings are often processes, not instantaneous events

Rome wasn't build in a day

point-based

interval-based

entities have a finite existence, a beginning and an end

#5 Time runs on a continuous scale

#6 organizing information: determining what makes an instance unique within each entity type

#7 we already know what we're doing. we figured out time years ago. that's why we have standards

significant disconnect between data model and user knowledge

we're still figuring it out.

let's talk about it
