Hi folks, I'm trying to get my first Zope product working. It shall: * manage dublin core meta data with each object (works) * deliver rdf/dc meta data info (works) * have both content (like a file but editable like DTMLDocument) and children nodes like a folder (works) * mirror the document hirarchy and meta data in the file system (half working) * don't evaluate DTML (for various reasons) (easy) * replicate hirarchy based on a subscription mechanism (not yet started) and be subclassable as ZClass and searchable. The latter two are the problem. I can't find how the ZClass.manage_subclassableClassNames() method collects which classes are subclassable. Furthermore the PrincipiaSearchSource() method is never called for some reason. I append the 0.0.0.0.0.0.0.1 ;-) version of my code, any help appreciated. /Jerry -- You can have it done fast, you can have it done cheap, and you can have it done well. --- But you can only have two of those at once. ---------------------------------------------------------------------------- """ We add documentation here the other day.
