I’m trying to visualize the FHIR schema on a big poster page so I can try to wrap my head around it.
I’ll tell you what I’ve done so far: I’ve downloaded the FHIR xml schemas (fhir-single.xml, fhir-all-xsd, etc.) and tried to put them through xsdvi, an open source xsd viewer. Unfortunately, that approach crashes due to lack of memory of my computer (16 GB). I’m curious if anybody uses a different XSD viewer and is able to get a nice zoomed-out look at the FHIR resources?
As a related task to illustrate what I’m trying to do: I’ve been able to load in the OMOP CDM spec into a database from some available Postgres SQL schemas and generate a database model diagram to get a sense of those models.
