A concept I've come up with independently (so far as I know).

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?
