[Zope-dev] [ZPatterns] DataSkin object ownership

Do DataSkins have ownership? I want to give multiple users the ability to add objects to a rack and only allow the 'owner' to view/edit the object. When a user adds a DataSkin to a rack does he get ownership of the object? I can't seem to get the ownership information for these objects. Is there a way to do this? BTW - I'm talking about virtual object that totally live in MySQL. Thanks, -Ben
