The problem of ontology
Data has a taxonomy: a description of what fields mean in context. 
But two different data tables can have an ontology: how meanings correspond. 
Example: compare
Name
ID
Phone
FullName
Number
Cell
An ontology relates data from two tables: 
Is Name==FullName? 
Is ID==Number?
Is Phone==Cell? 
Not really.
