   > @westonpace you are correct that this doesn't define how such dataset classes are built. That's left to the consumer, who will write their own classes that conform to this API.
   
   That would seem an essential API if this protocol was meant to be used by "table formats" to prepare "queries simple enough for query engines to understand".  So perhaps I am misunderstanding.
   
   Is this protocol meant to be used by "query engines" to "query a table format library as if it were a dataset"?
