interesting! that's a mathematically provable statement? or do you mean, most data can be represented as a graph? (I'm not asking antagonistically; I'm genuinely interested in the statement you made)
I will not address your question directly, but if you are interested in the mathematical treatment of equivalence between schemas, maybe category theory and the categorical query language (Spivak from MIT if I remember correctly) may be of interest.
