Hi, I am a newbie to Zope and have just gone through the tutorials and a little bit of ZopeBook. I have my own Custom Repository (RDBMS based) that has the features like storing flat files, folders etc. It also has provisions for user management. I have the XML APIs (lanuage is not a problem) for interacting with the repository. Can I store all the objects created in Zope in that repository? Further I also want that the authentication should also be done based on that repository (its like the roles and users defined in the custom system). Is it possible in Zope? I can comprehend that I would need to develop some kind of an interface that sits between the two for integration, but I wanted to know that whether it is possible in Zope or not? Its like when a user creates a folder or an object, the request is actually send to a module and then that module stores the object in my repository (may be the format is little bit changed) and vice-versa.
