Searching the Internet for module development documentation and tutorials yields results that can differ the 2013 OpenERP Technical Memento for OpenERP 7.
I am currently using the fleet module as main example for module development, but I wonder which would be the preferred modules as representative of the current API. They should ideally be up to date, small and simple modules. The fleet module is somewhat simple and relatively small, but comparing the OpenERP Technical Memento it does not seem to be fully up to date.
It would be uneasy developing a module relying in many OpenERP 6 / OpenERP 6.1 characteristics working in OpenERP 7 and (guess) Odoo 8 but candidatable for deprecation in upcoming Odoo 9 or Odoo 10 releases.
