Desirable features for user metadata include

optional per-column metadata
- probably as a collection of keyword-value pairs, value a simple scalar
optional per-table metadata
- preferably allow more complex, hierarchical
use of native table- or file-format-specific metadata features wherever possible
uniform API insofar as possible across different table and file formats

Likely implementation consequences:

complex per-table metadata may have to be stored in an auxiliary file, say a yaml or json text file
a table base class or mix-in to keep API streamlined
