What your Ontology represents
This ontology represents personal energy as the real resource we spend each day, instead of time. It splits energy into four kinds — Mental, Physical, Emotional, and Creative — and tracks how each one drains, recharges, and builds up as debt across a typical day.
The real-world scenario it models
It models a situation most of us know well: a calendar with 8 free hours, but a brain that's done by 2 PM. Morning meetings burn Mental energy during your Creative peak, so the deep-work slot you planned later is already broken before it starts. A 20-minute walk later restores Physical energy but does nothing for the Emotional drain from a hard conversation earlier. A regular calendar can't see any of this — but an AI agent that understood this model could.
Why the entities and relationships I chose matter
The entities work together to tell one clear story: a Person performs an Activity that drains or recharges an Energy_Type, made better or worse by whether it falls inside the right Peak_Window. Drainers and Rechargers are the specific things that cause it. Recovery_States quietly pay back the debt while you rest. When drain keeps outpacing recovery, Energy_Debt builds up and threatens the Person — which is what burnout really is. These relationships matter because they let an AI agent move past "do you have time for this?" to the better question — "do you have the right kind of energy, at the right time, with something left over?"
