Oooo, this is a good suggestion!!😮 I have never think about this direction before.

Because at the beginning, I only want to write some stuff for facilitating my testing process on the FHIR repository. So I use the python library for generating some fake data and put it on a REST service...
For using it as a facade... maybe a possible way as well, maybe can replace the generated data by loading the "REAL" data from the IRIS db, right?

It is just an example for generating FHIR bundle for testing purpose, we still need a FHIR server for storing the data

Yes, because I reuse the web application in the pervious article https://community.intersystems.com/post/writing-rest-api-service-exporti...
As I am lazy 😉
