I made a module: historical_data as an example in trunk-addons-
Here is more info from the __terp__.py file:
This module is a proof of concept on how to use historical data in Open ERP and
how you can easily inherit fields to create new type of fields. This module
shows two approaches to manage historical data. It based on an insurance
company need that manages contracts that evolves in the time. When a case is
opened, the information seen on the case should be the one of the contract
at that time.
* Contracts have versions valid in the time. Data are in versions of contract,
but displayed on the contract using a special fields.
expression based on the date is passed on the context) If you open a contract
from a case, the information you will see depends on the date of the case.
If you open contracts from the menu, the information displayed depends on the
current date.
* Partners management is based on the audittrail module. When you open
a partner from a contract, you will see the name of this partner related
to the date of the contract. Don't forget to activate a rule on res.partner
in the audittrail module to test this.
