My question is in relation with the reference information model (rm) and the clinical information model (cim) of fhir ?! when i read the specifications of the fhir model, my first response to this question is that, the fhir resources are the rm and profiling the resources results in a cim. But when I take a look to the 80/20 rule defined by the fhir authors, I also think that the fhir resources are an already cim that can be used without any profiling ! what the community think about that ? can you recommend me some articles discussing that ?
