Topic: How to get hl7.org/fhir valueset as json?
Misha Kaletsky (Jun 04 2020 at 16:58):
I'd like to get the json structure definition for a valueset + version pair. As an example:
The patient resource has a gender property, which has a valueset binding of http://hl7.org/fhir/ValueSet/administrative-gender|4.0.1
That url redirects to http://hl7.org/fhir/valueset-administrative-gender.html - and if you swap the .html at the end on _that_ with .json, you get a useful JSON-formatted StructureDefinition. But the string 4.0.1 doesn't appear anywhere in the redirect, so relying on this isn't a good idea.
Is there a URL scheme for converting from the original valueset url (http://hl7.org/fhir/ValueSet/administrative-gender|4.0.1) to a versioned JSON url (something looking like http://hl7.org/fhir/ValueSet/administrative-gender|4.0.1.json - but this just redirects to the html page)

http://hl7.org/fhir/4.0.1/ValueSet/administrative-gender works. It's on my todo list to get the |4.0.1 syntax working

Thanks - so the algorithm to get the json from an hl7.org valueset binding is
- get the url, e.g.
http://hl7.org/fhir/ValueSet/administrative-gender|4.0.1 - parse it to take the
|4.0.1at the end (or whatever number is there), and replace/fhirwith/fhir/4.0.1 - hit the parsed url
- get redirected to something like
http://hl7.org/fhir/R4/ValueSet/administrative-gender - follow the redirect, get redirected again to
http://hl7.org/fhir/R4/valueset-administrative-gender.html - replace
.htmlwith.json - finally, hit the json url
In doing all this, I feel like I must be barking up the wrong tree somehow. Is there a better way to go from what's in the Patient structure definition for gender to the correct json url? Also, I noticed that step 4 has the same result whether the original url is using 4.0.0 or 4.0.1.
