**A quantified self map.** A Data Manifest is a list of personal measures & metrics and the tools in which they are captured and stored. It [[Maps]] the various components together and forces the questions "why" am I capturing this data? "What" does it mean? "Where" does it live? "When" is it captured? and "How" am I going to use it? In my case, many (but **not** all) of my data would map into my [[PDW]]. # Example Datapoint Snippet Sleep Duration - Why - I believe consistently getting enough sleep enables better performance, increased happiness, and a better overall life. - What - the period in which my wearable says I slept each night. Does not cover naps. - Where - in my fitness app - When - automatically via my sleep-tracking wearable - How - I will review the sleep data nightly to determine if my habits need to change, and monthly to look for macroscopic trends. # Example Tool Snippet [[Oura Ring]] - Integrates with Apple Health - Covers sleep duration, [[naps]], bedtime & wake time, gross activity levels, and body temperature. **** ## Source ## Related - [[Lifelogging]] - [[Periodic Reviews]] - [[Master List]] - [[Capturing Logs]] - [[Quantified Weekly Review]]
