FHIR to OpenAPI translation

FHIR specify set of Resources with dataelements with specific datatype as informational model - StructureDefinition resource. So we have to convert StructureDefinition into JSON schema.

Also FHIR has specification of REST API by convention - http://hl7.org/fhir/http.html, and ability to extend API by custom Operations - http://hl7.org/fhir/operationslist.html

So we could generate swagger document from http://hl7.org/fhir/capabilitystatement.html and list of operations.

JSON schema

Convertion of Primitives

FHIR has set of primitive and complex types - http://hl7.org/fhir/datatypes.html

Polymorphic/Union types (Choice in terms of FHIR)

FHIR has the notion of union types (choice).

Current representation in JSON is postfix notation:

http://build.fhir.org/formats.html#choice
