Semi structured narrative data

[joostholslag]

Finally found time to read chapter 6 of the snomed guide. It now makes much more sense to me. The key takeaway for me is that the soft default context can be overruled by the information model, but must be computer processable. So a findings default context can be overruled by using it in a family history archetype. But it can’t be overruled from free texts ppm since computers cannot be assumed to understand that. I do hope all snomed implementers are aware of this, and they don’t just collect a list off all snomed codes for a patient in a single db column (without specifying the information model context. )
