Which was sort of the point of my post, if you recall... to make Z3 contet types first-class citizens in a CMF world. Now, there are some abstract things that CMF may want to incorporate as interfaces, such as abstract metdata about a type (display name, actions, aliases), catalog awareness (via events) etc. I imagine these should be described as interfaces and/or ZCML statements, at which point we can start to use adapters to make Z3 content types work in a CMF context. So far, I guess, the discussion has shown that we need: - An abstracted, events-driven alternative to CMFCatalogAware - An alternative to the portal_types/FTI mechanism that works in ZCML and/or through some generic interface with appropriate adapters - A way of getting ZCML-defined browser menus such as the add menu into CMF's add menu, and probably have similar mechanisms for actions in various categories. Of couse, as Alec points out, you need a whole bunch of other Zope 2 stuff as well, such as RoleManager etc. Perhaps having a content type that derives from ProtalType in a CMF world isn't so much worse than having one derive from Persistent in a pure Z3 world; you simply have to keep writing to interfaces and use adapters for additional logic and functionality.
