I'd want to add properties to a bunch of existing Zope objects, but these properties are in the form of nested mappings.

Is there a possibility to do so with or without (by program) the ZMI ?

I plan to store this as a string of text and evaluate it at runtime, but this is far from being optimal or easily maintainable.

any idea ? Zope does not yet have management pages for mappings. But, of course, you can create them.

When you implement the nested mappings with persistent classes (e.g. "PersistentMapping" or a "BTrees" class), then storing them should be painless. With normal dictionaries, you should not forget to inform the parent object about changes. Dieter
