A technical reference memento is available, to be used as a quick reference guide for OpenERP developers, often nicknamed a "cheat sheet".
The memento is usually updated for each major version of OpenERP, and contains a global overview of OpenERP's Application Programming Interface, including the declaration of modules, the ORM, the XML syntax, Dynamic views and Workflows. The memento is not an extensive reference, but a way to quickly find out how a certain OpenERP feature is accessed or used. Therefore each topic is only described in a few words, usually with a small example.
The examples in the technical memento all come from the example module idea, which allows an organisation to manage the generic ideas submitted by its members.
There are 2 versions of the memento. One is suited for printing in A4 landscape mode, with 3 columns of text per page, so that the whole memento is contained in less than 20 mini-pages (columns). The idea is to print and bind these pages as a reference booklet. The second version contains some more details and is formatted in A4 portrait mode, making it easier to read, but larger.
All versions of the technical memento (including previous ones) can be found at this location: Technical Memento
