Hi @Sebastian Thiele 

Here is the Encounter resource. I'm using IRIS for Windows (x86-64) 2024.1.1

url : http://localhost:52773/csp/healthshare/learning/fhir/r4/Encounter?&date=lt2024-10-27T15:29:00Z

Hello @Sebastian Thiele 
As per the documentation, date is fully supported search parameter. so, This should work prefix lt dates

I've 2 encounter resource in my FHIR server and I've tested with different dates ex: &date=lt2024-10-27T15:29:00Z period and it works to me

Awesome, It's pretty useful. However, If alias is retains like :history -Display command history its' really helpful and no need to define the shortcuts again.

Hello @Kevin Mayfield 

Instead FromJSON() write a custom class to parse the Binary Resource and set it into the FHIR model class. 

Here I convert the the data (which is the Binary resource -pdf or anything) to stream and set it in the data field of the  HS.FHIR.DTL.vR4.Model.Resource.Binary class

ClassMethod SetBinaryR4(json As %DynamicObject)
{
    Set obj = ##class(HS.FHIR.DTL.vR4.Model.Resource.Binary).%New()
    Set obj.contentType = json.contentType
    #; convert to stream to prevent from the <MAXSTRING> error 
    Set dataAsStrm = json.%Get("data",,"stream")
    Set obj.data = dataAsStrm
    Set obj.id = json.id
    
    #; set binary data element as stream for "Binary" resource. 
    ZWrite obj.data.Read()
}

Thanks!

Hello @Kevin Mayfield 

%GetNext retrieves values from the JSON object/array and assigns them to a local variable. However, the BLOB/streams exceed the maximum local length (3641144), MAXLEN doesn't cause the issue because it's a registered object, and the values are currently stored in memory. Therefore, AFAIK FromJSON is not suitable for handling such a large dataset.

Hello @Jan K

Yes, PS256 is not supported.  Can you try it in python JWT library packages.

Hello @Ali Chaib

1. You need to create you're custom DTL under "HS.Local.FHIR.DTL"  
2. Once DTL is created. Execute set status = ##class(HS.FHIR.DTL.Util.API.ExecDefinition).SetCustomDTLPackage("HS.Local.FHIR.DTL")  this and this will configure the customize DTL entry in the  ^HS.XF.Config global it's responsible for execute your DTL
3. Here is the documentation which covers most customization.
4. As I mentioned earlier, You need to the additional properties in respective SDA extension class.

Hi @Phillip Wu

If you're create new object values. Means, The %New() - Creates a new instance of object and It invokes the user provided callback method "%OnNew()". You can define your properties if you want in that call back methods.

Class Backup.Task Extends %Persistent
{
Property TaskName As %String;
Property TaskDescription As %String;
Method %OnNew(pTaskName As %String, pTaskDescription As %String) As %Status
{
 	Set ..TaskName = pTaskName
 	Set ..TaskDescription = pTaskDescription
 	Return $$$OK
}

ClassMethod CreateNewTask()
{
	Set taskObj = ##Class(Backup.Task).%New("DailyBackup","Runs a daily backup")
	Set st = taskObj.%Save()
}

}

 If you want to fetch the values of already stored. You have to use the %OpenId(id) and pass the id to open the instance of the expected object and you can fetch the values

ClassMethod GetTaskDetails(taskId)
{
    Set taskObj = ##Class(Backup.Task).%OpenId(taskId)
    Set lastRunStatus = taskObj.LastRunStatus
}

Hello @Ali Chaib

• SDA, or Summary Document Architecture is an intermidary format. It's used to easily convert between multiple data formats--such as HL7 V2, C-CDA, C32, HL7 FHIR, and others.
• I hope You are sending a GET request via HTTPOperation in FHIR interoperability production. You'll get the http response. There is no predefined transformation available to do it. You need to programmatically convert the response. I just convert the FHIR operation outcome to FHIR R4 outcome object directly.

  ClassMethod fhirresponse()
  {
  	#;Assume the json as a fhir response
  	Set fhiResponse = {"resourceType":"OperationOutcome","issue":[{"severity":"error","code":"not-found","diagnostics":"<HSFHIRErr>ResourceNotFound","details":{"text":"No resource with type 'Task' and id '33'"}}]}
  	#dim opoutcome As HS.FHIRModel.R4.OperationOutcome = ##Class(HS.FHIRModel.R4.OperationOutcome).fromDao(fhiResponse)
  	Write opoutcome.issue
  }
  

   

Hello @Ali Chaib

I could find the relevant SDA class resource  HS.SDA3.Task for the FHIR Task. AFAMA, there is no built in DTL or relevant FHIR model class available to transfer SDA to FHIR resource. for now, You can create a your own FHIR model class for Task and create a customized DTL under HS.Local.FHIR.DTL. package use the SDA3.Task as destination class for transformation.

Hello @JIM WHEELER

Seems you're trying to store the error message. If yes, You can use  $SYSTEM.Status.GetErrorText(status) to get the error text of the and store.

If you want to convert the list build values as a string. use  ##class(%Utility).FormatString() method 

USER>Set str = ##class(%Utility).FormatString($LB(1,2))
USER>zw str
str="$lb(1,2)"

Hello @Deepa Shahi

You can customize the SDA3 package. A native discrete SDA class is available to convert the data's from HL7 to FHIR and vise versa. In this case, HS.SDA3.Encounter is the SDA class. There is an additional editable extension class( "HS.Local.SDA3.EncounterExtension" - Encounter) available in these primary SDA classes to customize data elements. You can define all your required data elements in to this extension class and compile the package.

If you're using the SDA to FHIR conversion by DTL native approach.

Customize the DTL

You have to copy the existing DTL "HS.FHIR.DTL.SDA3.vR4.Encounter.Encounter" to "HS.Local.FHIR.DTL.SDA3.vR4.Encounter.Encounter". Before customizing DTLs, you need to specify a single package for all customized DTL classes. InterSystems recommends naming the class package: HS.Local.FHIR.DTL.

Now you can modify the newly copied DTL based on your requirement. this newly created DTL is not invoked by default. So, execute below code in your FHIR enabled namespace. The FHIR API classes use this HS.Local.* DTL packages while generating the resources ("Encounter" )

 set status = ##class(HS.FHIR.DTL.Util.API.ExecDefinition).SetCustomDTLPackage("HS.Local.FHIR.DTL")
