Topic: JSON Generation Tools
Pier Alberto Gibellini (Nov 27 2019 at 08:51):
Hi! In Dedalus we're looking for tools that simplify generation of example JSON resources based on existing profiles. We know about the tools available on the FHIR Tools Registry page, specifically the notepad++ plugin, but as far as I know it builds JSON starting exclusively from the core FHIR structure definitions. Has anyone suggestions about other existing tools? We're using STU3. Thanks!
Ward Weistra (Nov 27 2019 at 11:14):
Simplifier.net has an (currently in beta) tool that allows you to generate examples/instances from STU3 profiles. For example, going to https://simplifier.net/nictizstu3-zib2017/nl-core-patient, click the Tools button top right and choose whether to generate an Empty instance or let Simplifier fill in some example data where possible.

This only generates XML at this point, but this can easily be converted to JSON. For example by using the Simplifier.net/snippet tool: https://simplifier.net/snippet/wardweistra/3

the notepad++ plug-in can generate from any profile as well as from the base definitions

We have this project for Xmas hackathon - so probably in a couple of months you will have such tool :)

We've thought about creating a system in Synthea where you drop in an Implementation Guide, and some set of mapping files (example for US Core observations, maybe other mapping files containing FHIR Path or other expressions that instruct Synthea how to populate certain fields in the profiles from the patient data. We have a pretty good one-off solution for US Core in place, but we need to abstract it to support any arbitrary IG. Happy to get help if others are interested.

@Ward Weistra
This is awesome! Please add this to R4 :pray:

Thanks @Simone Heckmann, we were waiting to see user demand for that, so I'll add your name to the list!
Of course we're not creating any realistic data, just data that should pass validation. We'd be very happy to see @Jason Walonoski's Synthea support profiles outside of US-Core!

I actually find the creation of an empty resource (with fixed values) even more useful than adding test data.

Thanks Grahame! But to use it, we shall start from some FHIR package containing the profiles we need to generate the JSON for, right?
Grahame Grieve (Nov 28 2019 at 15:54):
well, it needs to get the content from somewhere, and packages are the easiest way. but I think you can get the profiles from somewhere else too

I know that @Michael Lawley at CSIRO has been thinking about something along these lines in Australia. Would personally love to see this!

Would also love to be added on this list since we're working in Simplifier/R4 and just in the starts of creating IG's/ResourceGuides for clients!

Thanks Tobias, I'll let you know when we get around to it!
