Hello,
From the package.tgz that is available for download from:
https://nrces.in/ndhm/fhir/r4/downloads.html
there are two files: “ig-r4.json” and “ImplementationGuide-hl7.fhir.in.json” that seem to be implementation guides, which of these is the right one to use for FHIR resource validation ?
Thank you in advance !
