Hi Ime, There is some information on the developer's wiki http://www.openehr.org/wiki/display/dev/Developers+Home
I personally believe (though I haven't yet proved it). That it is much more efficient to use an object database. Realized by code reduction (30%?) and ease and speed of queries. A project for another day is for me to write this up and post it on the wiki as well.
