Schema for medical/clinical data?

[alessandro bottoni <alessandro.bottoni@infinito.it>]

Maybe this is quite OT but... does anybody know of any schema suitable for 
holding medical/clinical data (blood analysis data, pneumologycal data, 
etc...)? I'm consulting for a worker's health medical center and I would 
like to store their data into a OpenLDAP directory. Any suggestion about the 
schema?

Thanks in advance

PS: I visited the OID databased at http://www.alvestrand.no, already.
