Are you wishing to add fields that will show up in edit forms? Or, just
adding attributes to objects?

If the latter, just do it. Simple data types like strings may be added via
Python attribute notation and will automatically persist. You may need to
explicitly commit the transaction if it isn't occurring within a request.

Compound data types (lists, dictionaries) don't automatically persist their
components. But the ZODB has great support:

If you want to add editable fields to existing content types, then extend
the schema of the content type. For Archetypes content types, use
archetypes SchemaExtender. For Dexterity types, just edit the schema.
