I know this has been asked before, but I need a definite answer before we can pick ZOPE as our platform of choice for a project. One of the major requirements is to be able to view history for files (docs, images, etc), and be able to view the actual file @ any point in the history. Basically, we need "history" functionality that ZOPE currently provides for such objects as Scripts, DTML Methods, etc. The question is, has it been done before? Is there a ZOPE product that has this functionality. Would it be difficult to extend an existing class to add this functionality? I tried to follow one of the suggestions in this mailing list (extending the class from History.Historical), but that rendered my product invalid. Any help would be appreciated! Regards, Daniel.
I'm not sure if there's a Zope product to do this, but the way that we are accomplishing that is by using wget from a cron job. That gives us a daily "static" history that is available for viewing through a "history" skin we put together.

When you need history records arbitrary long (for a single instance), then you can never pack the ZODB and never get rid of any old version. When this is not a problem for you, then the basic functions (to access an objects history) are available for any object. However, visualization of the differences can easily been implemented for a small set of specialized objects. Dieter
