Nice column. A much needed differentiation in my opinion.
I start the 'cycle' with purpose. Then as you say comes data collection. The beginning of study.
Followed by enough data assimilation to form a body of connected data and thus knowledge.
Then the cognitive, conceptual understanding. All this I see as stages of a natural path of study.
So that being three stages I would personally say there are quite a few more before wisdom.
Nice thought-filled piece as usual.
