Dave and Karsten, If I am not mistaken, UNIX was designed exactly as a reaction to the "Big IT Way" of implementing software/operating systems (with 100k function points, many of which tend to fail in a highly inter-related fashion). In the arena of EHR, both GEHR/OpenEHR and OIO propose a domain-specific layer (archetypes/forms/workflows etc) aims/claims to make it easier to build modular applications. Each "application" will provide a limited few number of "function points". Each "application" can be authored easily by domain experts without programmer resources (avoiding some of the associated risks). If any one "application" fails, the problem will be easy to isolate, locate, and fix - and hopefully affect other applications in a predictable and limited fashion. (Thomas, please feel free to point out my ignorance if I have mis-characterizing OpenEHR in any way.) Best regards, Andrew --- Andrew P.
