That's pretty much a truism: data is all dirty. You spend more time (2x? 10x?) dealing with that, than dealing with the normal data. My son has a startup. Its trying to collect certain datasets and organize them in a tool. But every dataset of this kind is dirty, in a different way. They identify unique assets with different identifiers, or a fingerprint, or nothing. Its crazy trying to eliminate duplicates, find references between or even simply import a dataset. On the plus side,that's a barrier to entry for a product of this kind.
