A very helpful repository to generate synthetic FHIR compatible data shared by @Phillip Booth 
 

E.g. to generate data for 5 patients in an /output subfolder of a current folder call:

docker run --rm -v $PWD/output:/output --name synthea-docker intersystemsdc/irisdemo-base-synthea:version-1.3.4 -p 5

Which you can load then into IRIS for Health with:

zw ##class(HS.FHIRServer.Tools.DataLoader).SubmitResourceFiles("path/output", "FHIRNamespace", "/restapi/endpoint/fhir/r4")

Turned out we'll not fix this soon. module.xml stats RULES for gathering the package and for a clean up too.

So if you delete the package with rcc.PCG in module.xml will delete literally the package rcc from the system with all the child classes.

This is how it works now.

So for now please describe the exact feature package in the module.xml.
