a_thesis,

Semantic data dissonance is quite the colorful term for heterogeneity, which has previously been categorized as either "semantic" or "structural". Hmmmmm.

Just about any formal publication on heterogeneous databases, multi-databases, data integration, and heterogeneity itself might get you started in the right direction.

To get you started, here are a few papers that are probably related:
