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

The long slow death of UML
The Unified Modelling Language aka UML has been around for 22 years, as you can see from the OMG UML page. We use it extensively to publish the openEHR specifications, in a similar way to many other organisations. Developers often … Continue reading
