Hi Klavs; I am going to describe where we are going here with the API. We have abandoned all appearances of supporting any db's other than PostgreSQL and will be re-engineering the API over the next year or so. 1.3 will be the first release with some of the API re-written.
You can divide the logic of the application into really a few areas: 1) Data logic (M) 2) UI Generation (V) 3) Application logic (C) Most of what is in the SQL-Ledger PM's at the moment is data logic. Data logic will be moved entirely into the db via stored procedures to the greatest extent practical. A very light-weight object model will sit on top of these. UI Generation is going to be done in Template Toolkit at first and then XML/XSLT as the API matures. We will probably support both TT and XML/XSLT in parallel. The RESTful API is essentially treated as a UI. I assume that by the time 1.3 comes out, we will have a better idea of what sort of logic the application still has to handle outside this. Certainly authentication and some other areas need to be looked at here. Once we really start moving to this model, we will probably find that most of this is simple proceedural stuff. Note that since most of the data logic will be contained in the db, it will be trivial to write other apps that interact with LedgerSMB in any other language. Hope this helps, and sorry for the delay.
