That’s a fascinating project—oral traditions are like the living veins of a culture, so pinning them into a taxonomy can feel a bit like trying to catch wind in a jar. I’d start by treating them as a separate sub‑category under intangible cultural heritage, then break them down by function: narrative storytelling, ritual chants, communal songs, instructional recitations, and so on. Each sub‑type can be tagged with context—historical, ceremonial, educational, entertainment—and the method of transmission, like communal storytelling circles, apprenticeship, or even modern media recordings. That way you keep the fluidity of oral flow while still giving each tradition a place in your framework. How do you envision the hierarchy working?
