Right. We can also add another useful field to base clase, instead of 
item_type. item_table: 'vaccination', 'lab_request', 'allergy'.

Sure, i agree.

I'm not really sure about it, but at first maybe we could use  'pk serial 
primary key' sql table field, at least to keep some track of the item...

Oops, sorry it's correct ;) . We could provide in vos those simple 
get_XX_text_dump() just, as a quick text dump of its contents (that maybe 
could be used later in gmClinicalRecord.get_text_dump())... But, the export 
tool would provide some methods that retrieve adecuate values object's fields 
to provide a more estructured text (as Karsten proposed):

Right 

Best regards,

PD: I'm now trying python eclipse 2.1 plugin (http://www.sourceforge.net/
projects/pydev/), it's yet alpha but really nice as editor, class navigator, 
and cvs ;)
