Ensemble supports Data Transformation Language (DTL) for describing data transformations. DTL is an XML language. Ensemble provides wizards and graphical tools for creating, editing, and testing DTL transformations. A data transformation is a Caché class like the following. If you prefer you can use Studio to edit the class definition directly and bypass the wizards and graphical tools.
I am converting xml message into HL7 message but the input XML message contains pdf which is converting into base 64 and getting mapped to OBX:5.5 in HL7 message and sending it to downstream
In Downstream service i am using normal HL7 TCP class EnsLib.HL7.Service.TCPService but the message looks like below i am not sure why stream is taking as another segment in HL7 message,
I have a theory that I could use an HL7 Data Transformer in a rule without specifying a specific DocType. I want to use the same DTL for a variety of different DocTypes. Here is my very simplistic DTL so far:
So, here is a novice question; but, I can't seem to figure out how to do it, or find any comments. I simply want to close out this DTL, under the Interoperability / Build / DTL screen:
There do not seem to be any buttons to 'close' the current DTL item. I tried logging off and back on, and, it brings it right back. Ideas?
I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.
I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.
I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object.
When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router
We are receiving the report in text format and it has special characters like ', - like that in the text. Source system is using the UTF8 encoding format hence the text is showing as ' � ' . Is there a way to convert the utf8 to actual character in the DTL.
is it possible to kill/suppress hl7 message in the DTL (data transformation).
in cloverleaf, it is common practice to check the value in message, for example pv1:7.9. if the value is certain word(assigning authority) then send the message over to destination, if it is not, kill the message
how would this be done in InterSystems ? does that need to be done in the rule instead? or can it be done in the data transformation? if it can be done in data transformation, how can it be done?
We are using a DTL transformation to take HL7 and transform into custom XML. But the nodes in the resulting XML are appearing out of sequence - and therefore failing validation against the schema.
The XSD schema for the XML looks fine when imported into Ensemble: root node in the XSD looks like this: And shows in Ensemble like this:
I did a very usual hl7 adt transformation DTL, but it is with a customized schema, like ADT_ALL, it is a structure that tries to cover all the ADT schema scenario so we can use 1 type for all ADT messages.
the DTL tests fine in DTL test, with all the segment transformed correctly, but once I put it to test, to send message through source and the message after transformation can only go to MSH, EVN, but won't transform other segment like PID etc.
I thought I knew how to return a Response from a Business Process back to the Source Config Name, but I guess not.
I am working on a Proof of Concept, that the Request Message Class would determine a "Route" within a Business Process to make a FHIR call (search, read) to our External FHIR repository, and return back the HS.FHIR.DTL.vR4.Model.Resource.xxxxxxx as a Response to the Source Config Name.
My team is exploring options for handling timezone offsets in DTL and we’re wondering if there are any built-in methods available — ideally low-code or no-code solutions. Specifically, we're looking for a way to adjust timestamps based on the date and whether Daylight Saving Time (DST) is in effect.
For all Prosthetics orders: when ORC-1(Order Control) is "NW" (New Order), need to update OBR-18(Placer Field 1) based on PV1-2 (Patient Class) value. assumption is that the selection logic is that all prosthetics orders with OBR-18 field is always blank. Description : If PV1-2 is I, insert I in OBR-18 If PV1-2 is O, insert O in OBR-18 If PV1-2 is E, insert O in OBR-18 If PV1-2 is P, insert O in OBR-18 If PV1-2 is R, insert O in OBR-18 If PV1-2 is B, insert O in OBR-18
Transform the object obtained in first point into another one using DTL
Sends the second object to an operation
The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.
I have tried to make transformation before making CALL's, I mean:

I was using VSCode to edit a DTL because it seemed easier to copy/paste code from parts of the DTL I was editing. I tried to add <sql> tag and code to call a SELECT statement, but when I compiled I got the following error...
ERROR <Ens>ErrInvalidDTL: Invalid DTL
> ERROR #5490: Error running generator for method 'GetSourceDocType:osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'
We are receiving an ORU message and the vendor is requesting that we append a new OBX segment at the end of the message and I wanted to reach out to see what options might be available.
So far, I tried the append action in the DTL editor with a single OBX-3 field but it seems to be appending to the field directly instead of creating a new OBX. I've started looking into if whether I could use a function but wanted to first check with the experts on the Discussion here in case there's an easier way to accomplish this. Thank you.
Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.
We are using a DTL transformation to take HL7 and transform into custom XML (XML is a virtual document, held in an EnsLib.EDI.XML.Document object). The schema specifying the format of the XML says one element should occur no more than 24 times (maxOccurs="24" in the XSD schema). However, the transformation to produce one such element always produces 24 elements, all but the last one blank, when tested stand-alone.
I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.
How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
Do I have to then do another "fromDao" to pull the list into string format?
How do I navigate around the lists that are in a FHIRModel response, to extract the string values?
I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource
{"resourceType":"Patient"}
so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?
I am trying to add a value to my concatenation string and the value is not being inserted in the right place. I am adding onto this code from another developer and cannot seem to get it to work. The only code I have added is underlined in bold red.
