Dialectical Hermeticist
Now I kind of want to do a RP with a nomadic tribe that is incredibly scholarly. Perhaps they're nomadic because they want to travel around and learn more about the world.
I'd suggest looking to perpatetic groups for inspiration, particularly around India. If memory serves, the Bedouin had quite a rich scholarly tradition at some point, too (but finding scholarship on the topic is, ironically, an absolute pain the arse).
The main obstacles are recording methods, transporting recorded information, and a propensity for nomadic groups to be strongly traditionalist which is great for some fields of study and anathema to others. Purely oral records can be subject to fierce dogma or significant drift, as well.
