Hello... Okay, I'm still staring up at the ZPatterns learning cliff as I write this so forgive my ignorance. I'm looking at ZPatterns WRT to 'dynamically generated dataskins'. You what? Well, okay, I'll try and explain... Firstly, I'm assuming that DataSkins (or their subclasses?) are first-class zope objects, can be 'added', copied, pasted, have security tabs, can be catalogued, URL traversed, etc, etc. Is that assumption correct? I hope so :-S If it is, is there something which can generate DataSkins on the fly? ie: in the same way an AttributeProvider supplier attributes to an object, is there something like a 'DataSkin provider' which provides whole dataskins to a folderish object? Finally, and this is the important bit. Can one of these folderish objects also _be_ a DataSkin? So, to word it differently, there is a root 'DataSkin provider'. This provides DataSkins which are folderish and are also 'DataSkin providers' themselves. Why do I want this? Well, think objects in a tree where the parents/children are stored as a list of names refering to other objects. In addition, objects may have multiple parents, etc... Any ideas? Where should I start reading? cheers, Chris
