Apologies that this is perhaps not the right forum, but I sense there is a fair crossover between the CEN and openehr communities so I thought this might reach the right ears..
I have been perusing the draft cen 13606-1 specification in my exploration of all things openehr related (given the large overlap in ideas.. two level modelling etc). I was wondering if anyone had any ADL archetypes based on the 13606-1 reference model? I am going to hand craft some as an experiment but would love some that are more clinically valid than my idle musings.. On related notes - I do not normally have any access to cen materials and am completely in the dark as to the whole cen standards process, but I take it that 13606-1 is in draft mode, awaiting a vote on acceptance? From my brief reading, it seems not ready for 'prime time'.. two that immediately came to my attention were the ED support type that has a compulsory "language" attribute (which means what for a photo?) and URI reference? Maybe the UML diagram is wrong or something but it seems to indicate that both of them compulsory, when surely they have to be optional attributes? (I have just read it again, and in their defence, it does say they are waiting for a new datatypes standard to be published so perhaps they have not looked too much at this area).. But even the examples seem confused.. annex C has an 'informative' sample ehr_system.extension = Whittington ehr_system.assigningAuthorityName = NHS ehr_system.valid_time = 1/1/1990 - 1/1/3000 ehr_system.root.oid = 9876543211 Why would any health standard be promoting an example using 'magic' dates to indicate infinite time ranges?? Surely these are open ended intervals rather than actually statements that this ehr_system is going to cease to be valid in the year 3000? I know its just a sample, but if the sample doesn't show the proper techniques, what chance does any programmer reading the spec have to do it correctly.. I also am under the impression that 13606-2 will be an effort to standardise the expression of archetypes? Is ADL in its current form a contender for that standard? How far along is the standards process and are there any avenues to review the work (for non-europeans)?
