[Zope3-dev] Managing via Component Interfaces TTW

[Leonardo Rochael Almeida]

Hi,

I like very much what I read below. In several Zope projects I'm
involved I use folders as collection objects, much like tables in a
database, and I would very much like to be able to do like this in
PythonScripts

objectlist = SomeFolder.objectItems(interface=SomeProduct.SomeInterface)

or maybe even

objectlist = SomeFolder.objectItems(interface="SomeInterfaceName")

which would be much more functional than the selection thru meta-types
due to their inherent limitations.

Being able to ZCatalog that would be even cooler.

I think we should take the decoupling of interface from implementation
as far as we can inside Zope.

Cheers, Leo
