Thomas, Thanks! Let's try an example, please let me know if it is wrong: Act - write progress note Entity - a physician called Andrew Ho. Role - physician Participation - "physician" (role) can "write progress note" (act) Act_relationship - after "write progress note" (act) can "sign progress note" (act) Role_link - all psychiatrists (role) are physicians (role).

A Psychiatric Record (folder) - a Progress note (composition) - treatment plan (headed section) - delusion (item) - [haloperidol 5mg (item) PO qHS (item) prescribed today] (cluster) - "haloperidol prescribed" for "delusion" (link) - show all items in the Progress Note (view) [reference: http://www.chime.ucl.ac.uk/work-areas/ehrs/EHCR-SupA/13606v1_8/sld017.htm] > - and EHR API is a query and modification interface to the EHR, enabling > applications and other services to access a given EHR server. I am not sure what this could look like. Could you provide a simple example? Thanks, Andrew --- Andrew P. Ho, M.D. OIO: Open Infrastructure for Outcomes www.TxOutcome.Org
