Hello

At this moment, I could not find a way to associate data definition to a specific column.

In wiki page you can specify description of a dataset and be free to describe whatever you want (including columns descriptions).

But in my mind there should be a description per column and a description at VDS level.

example : DESCRIBE TABLE should also display definition of columns while VDS should decribe definition of VDS and AI agent understand/use parent lineage of VDS to use definition of columns (eg : group by, where, sum(), …).

Any updates,ideas or hints by Dremio to be able to place definition at column level would help.
