If they point to an old version, then there weren't any significant
changes, and the old documentation should be accurate.

The relevant pages list objects for those, but it seems I never filled
them in.

In any case, they follow the same behavior of all other database-derived
objects. They can be accessed by the class constructor by using the
table's primary keys, and all columns are accessible as attributes. You
can alter the attributes and run .update() to push the changes, or you
can feed those changes into .update({}) with a dict argument. You can
create a new, empty object, populate it, and then push it with
.create(). You can delete an existing object with .delete().
