FHIR Fixes – the Observation.value problem
As described in some detail in this earlier post on the FHIR formalism, a number of FHIR Resources contain ‘choice’ attributes of the form attribute[x], such as the one shown above in Observation. These are mapped in the FHIR UML … Continue reading
Fixes for FHIR – the Admin Resources
In this post I revisit the issues with the FHIR Resources described in the earlier post – A FHIR experience: models or just definitions? To summarise: FHIR has no semantic inheritance, only a generic structural inheritance of Resources from abstract … Continue reading
Improving Process State Representation in FHIR
In this post I document further observations on the FHIR resources, made during the transcription of the DSTU4 FHIR resources to the BMM format used in openEHR, as described here. This post examines the definition of process state in FHIR … Continue reading
FHIR versus the EHR
One of the many things the FHIR silver bullet hype claims FHIR will solve is the EHR, along with Clinical Decision Support (CDS), Care Pathways, and who knows, paving driveways and launching spacecraft. I have made various arguments against silver … Continue reading

This is a second instalment of a technical review of the HL7 FHIR resources. As described in the previous post, this review is the result of an element-by-element transcription of the FHIR DSTU4 resources to the openEHR BMM (Basic-meta Model) … Continue reading
A FHIR experience: consistently inconsistent
In recent work I am involved in, the HL7 FHIR DSTU4 resources were converted to the openEHR formalism known as Basic Meta-Model (BMM), which is published as an open specification. BMM is an object-oriented formalism, conceptually similar to UML (minus … Continue reading
