[Zope] Automatically adding properties (keywords) to folders

[Terry Jones]

I'd like to set up a folder in Zope with the property that when an object
is put into it, the object has a keyword added to it automatically (and
when the object is moved out of the folder, the keyword is removed).

If you could do this, you would have a nice way to maintain a collection of
such folders and have their contents appear elsewhere in a collection of
Plone Smart Folders (using keyword criteria).

Can anyone tell me how I should best go about doing this?

I can imagine writing some python to run once in a while, find all the
contents of the folder, add the keywords, etc. But that's far from being an
ideal solution.

Any pointers would be much appreciated.

Regards,
Terry

Thus, you want to customize the folder's _setObject and _delObject.

Define your own Folder class deriving from Zope's standard 'Folder'
and reimplement _setObject and _getObject the way you like.
