Two kinds of notes:
- Episodic — "meeting on Jan 12th", "chat with Priya on Jan 24th"
- Semantic — "Alice leads Project Porcupine"
Most pkm tools treat these as the same thing
But really
- the episodic notes are closer to events
- semantic ones are closer to a materialized view
When the events conflict (Jan 24th — Bob now leads), the view should update(?!)
