How to persist a bundle with resources not still created on my fhir server? -

in our cda2fhir mapping engine generating fhir bundle cda document, bundle has resources without real fhir ids our server. example, 1 patient , compartment objects procedures, medicationprescription, relatedperson, ..... need persist resource network individually, linked between them.

how should created resources in bundle in server? think should persist sorting (first patient, practitioner, , relatedpersons, , later rest of comparment resources). there approach this? endpoint?

thanks in advance suggestion or guidance.

regards

within bundle, it's legitimate give resources urns rather urls. i.e. urn:uuid:.... or urn:oid:....

this covered in single line in section 1.12.3.4.1: "note internal references allowed uris rather literal urls."

if create multiple documents reference same patient, observation, etc., uuid or oid used identify resource instance should same in each document produce.
