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().
