How to convert fhir R4 to SDA through iris, is there any specific link

Hi Xiong,

To convert FHIR R4 to SDA you have to use this helper class :

HS.FHIR.DTL.Util.HC.FHIR.SDA3.Process

This class take in input a message of this kind : HS.FHIRServer.Interop.Request or HS.Message.FHIR.Request.

So if you want to convert an json FHIR file to SDA, you have to read the file from a business service cast you file to one of this message and send it to the helper class.

Here is and Business service example of reading fhir json files :

Class BS.FHIRFileService Extends Ens.BusinessService
{

Parameter ADAPTER = "EnsLib.File.InboundAdapter";

Property TargetConfigNames As %String(MAXLEN = 1000) [ InitialExpression = "BusinessProcess" ];

Parameter SETTINGS = "TargetConfigNames:Basic:selector?multiSelect=1&context={Ens.ContextSearch/ProductionItems?targets=1&productionName=@productionId}";

Method OnProcessInput(pDocIn As %RegisteredObject, Output pDocOut As %RegisteredObject) As %Status
{
    set status = $$$OK

    try {

        set pInput = ##class(HS.FHIRServer.Interop.Request).%New()
        set tQuickStream = ##class(HS.SDA3.QuickStream).%New()
        do tQuickStream.CopyFrom(pDocIn)
        set pInput.QuickStreamId= tQuickStream.Id


        for iTarget=1:1:$L(..TargetConfigNames, ",") {
            set tOneTarget=$ZStrip($P(..TargetConfigNames,",",iTarget),"<>W")  Continue:""=tOneTarget
            $$$ThrowOnError(..SendRequestSync(tOneTarget,pInput,.pDocOut))
        }
    } catch ex {
        set status = ex.AsStatus()
    }

    Quit status
}

}
