Folder w/ Customizer support. When you use this, the DataSkin instances
appear in the ZODB, and look like normal ZClass (or whatever) instances.

Use Specialists. Specialists contain Racks. Each Rack manages a
particular class of objects. You can store objects in the ZODB inside
the Rack, or alternamtively, you can get the data from external sources.
You can also combine both kinds of data to provide the attributes for a
I've just completed a fairly complex ZPatterns project, designed broadly
according to Coad / ZPatterns / wisdom from PJE . I used both
approaches, and, based on that experience, I suggest you use the
Specialists approach unless you have a pressing need to have your
dataskin instances "rooted" in the ZODB. In the latter case only, use
Folder w/ Customizer support.
Other the other hand, if you want to design a "normal" Zope application,
but just get the flexibility of using Attribute Providers and Skinscript
to coordinate your dataskin instances, then use Folder w/ Customizer
