Truth Project
The fake json data are generated using https://www.json-generator.com/ and the script in wdbfakedata.txt.
See an example of how the JSON Database will look in JSON Version 3 Example.pdf.
At the top level, we have community_data and user_data. community_data will hold
the values we need to calculate the comparison metrics (example: "you're in the
top 5% for hours slept"). We can calculate the percentiles using the arrays
from community_data and the user's value for time spent on that category.
The user_data array has one object per user. Each user object has various fields,
including the activities array that contains one object per day the user recorded data.
If the user did not record data on a given day, there will be no activities object
for that day.
Each object in the user's activities array will contain totals for the amount of
time spent on each category. It will also contain an array events filled with
event objects that describe each event's start time, end time, and duration.
Remember that TRUTH only supports start & end times in 15 minute increments, to
keep things simple. The duration field for each event as well as the activity
totals for each day are type double with units in hours. Note that 15 minutes
is 0.25 hours.
We haven't discussed this yet, but duration and the daily totals will have to
be calculated at some point, either on the front end or the back end.
