[Zope3-Users] History of an Object

[James Allwyn]

Hello,

Transactions and undo functionality seem to be well-supported in Zope;
I assume that the past states of objects are stored in the database.

For our application it would be useful to access these past states for
an object. I have in mind something along the lines of the wikipedia
History tab, which allows you to see what an object was like at a
given past instance.

The actual Undo functionality is not too important for the
application, and there are certainly users that I would want to be
able to view the past states but not be able to revert (undo) to it.

Since the undo data is already being stored it feels like I should be
able to tap into this to access the past states, without having to
actively store anything - does anyone have any hints on how I might go
about this?

Thanks,
James
