Just thinking out loud, what if normalized data, like time-series entries were notes. It's inefficient but extremely powerful.

Each note would have to reference the table name, and any other meta information. But then each data point is now a signed entry available to anyone for filtering/sorting.

Anyone could provide their own data to compete for that data point.

Consumers of that data set could then choose their sources, average their sources, etc...

This would changed the way data science, finance, etc... is done.

Think crowd sourced excel.
