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.

Documentation.

I'm creating a Business Process that:

  1. Transforms one object into another using DTL
  2. Sends this object to an operation
  3. Transform the object obtained in first point into another one using DTL
  4. 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:

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.

HL7 DTL formatting

I need a DTL to handle this.

Any ideas appreciated.

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

New at DTL. I need some pointers on this DTL

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 starting to see this error message...

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.

Thank you,

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 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.

Hi, I am coming unstuck with a current mapping from HL7 to XML using the DTL editor with an XML schema (imported by XSD).

My output keeps prefixing the elements with "xsd_2" despite this not being defined in the targetnamespace within my XSD file.

Would anyone have any idea as to where this is creeping in? Any advice would be greatly appreciated.

My XSD namespace etc are setup as follows:

Hello,

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?

Thanks

Has anybody encountered this before?

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 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'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:

I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.

Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure.
