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.

Hi,

Can anyone point me to an example of a DTL & Class method that can pull a base64 encoded PDF out of a MDMT02 message?

This is really asking for two things;

- how to make a DTL that extracts a specific subfield of an HL7 2.3 message into a message of its own,

and

- how to transform an base64 encoded document into its original binary form for writing to a file.

I'd also love to see an example of an HL7 2.n MDM^T02 ==> HL73.ITK2 non-coded CDA

DICOM to HL7

We have a case where a vendor can send us more information in the DICOM message rather than in the HL7 result message. In theory it should be possible to take a DICOM and convert it to HL7, stupid question is has anyone done it before? Does anyone have any good examples of a DTL they did to show me how to setup the message structures and translation?

Thanks

Hello All.

In need of some help.

We are currently migrating Interfaces from JCAPS to HealthConnect 19.1 and have done a lot of work on our Dev server. I am looking to copy/export this work over to the Test server and have managed to export the production and Rules, HL7 custom Schemas etc. The only thing left now are the Data Transformations but so far I can only find ways of copying the transformations over individually. Is there some way to copy all of the transformations we have produced in our namespace to another server in one go?

Thanks

Someone may have asked this before but is there a way to return the TRACE statements that we have placed in the Data transformation within the DTL Editor Testing Tool (EnsPortal.Dialog.TestTransform.cls)? Is this something we can get in an Enhancement request in for?

It would save sometime in troubleshooting where an error might be in the DTL.

Just wondering...

Thanks

Scott

Hi,

I have an Ensemble DTL which is suppose to translate the inbound XML document to an outbound XML document.

I need to test if a particular XML element exists, to perform some translation.

In the DTL I have the following,

<if condition='source.{element1.element2.element3}'>

<true>

    // do something

</true>

</if>

How do you use if statement to test the source XML document to see if a particular element exists in the source doucment.

Thanks,

We have one user that is having issues in Ensemble via browser. The two issues she reported are:

- If she opens a DTL, she has to Save or Compile the DTL before she is able to edit anything in the Actions tab. Typically, you can simply open the DTL, click on a line, and edit the Actions.

- If she opens the Tools tab and clicks the Test button, she does not get a response and it eventually times out on her. Typically, clicking the Test button will open a new window where you can paste a message to test your DTL with.

HL7 - FHIR

Hi All,

I know hundreds of people have done this but I'm looking for some DTL's as a start to do HL7 to FHIR, I appreciate everyone's HL7 is slightly different, but just some starter DTL's would be much appreciated? Can anyone help?

I have an incoming data partner who occasionally passes a non-ASCII character in some free text fields which is causing some downstream systems to be unable to accept the message. Ideally I'm looking for some way to just process the entire message as a data transformation applied in the business rule, as we already have a pre-processor transform to remove the PD1 segment.

Hello,

I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.

I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).

The transformer is being used in a business process.

This is the code used in the transformer to encode the stream to base 64:

We are receiving XML documents and storing them. When we click to go into the clinician portal and again to view a patient, we can see the documents but none of the data is mapped to their respective buckets, i.e. allergies or medications.

I am thinking that I need to build an XSLT parser and change the format to SDA3, is this an appropriate approach? Or would using the Data Transformation (Ensemble -> Build -> Data Transformation) be a better idea? Lastly, if the XSLT idea is preferred, where would I call it within the stack?

Folks

1) What's the correct way to check for an existence of a segment? So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

source.{ZEF:Counter}=1

Hi, guys,

I've written a DT for a partner which transfers a csv file into SDA3.

I', using record map to gather data from a folder storing csv files and using the DT to tranfer the records into sda3 entities.

The followings are the codes of that DT:

Class POC.DT.CSV2SDA3 Extends Ens.DataTransformDTL [ DependsOn = (User.PhysicalExam.Record, POC.SDA.Container) ]

{

Parameter IGNOREMISSINGSOURCE = 1;

Parameter REPORTERRORS = 1;

Parameter TREATEMPTYREPEATINGFIELDASNULL = 0;

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:

leading zeros

Hallo, I need a Ensemble transformation to fill up a 6 or 7 digit Number to a 10 digit string with leading zeros.

123456 --> 0000123456

1234567 --> 0001234567

Thank you!

I'm testing an HL7 2.4 -> HL7 2.3.1 set of transformations. For the time being the source (service) and sink (operation) are file adapters. What I'd really like is to be able to save the output file with a name matching/containing the input file name - but as the DTL transformation in between uses "new" rather than "copy" it looks like I'm losing (some of?) the metadata, including the "Source" field (Body tab, message viewer).

Is there any way of preserving the Source field so the OutboundAdapter has access to it?

Suppose I have an image and need to convert that image into a PDF for inclusion in an HL7.

I know that Zen Reports can display an image in a PDF but I do not want to view the image in a web page. I just need to convert the image to PDF in a Process and then include that PDF in an HL7. The workflow would be like this:

Get image -> Convert image into PDF -> Include PDF in HL7 OBX.

I know how to do the last part to include PDF in HL7 OBX. Just need ideas on the first part.

I am having an issue with the output file format on a production where quotes (" ") around column values are being removed from the imported file. For example, my input file is a csv formatted as such: "123", " ", "ABC". The output file format that is being generated produces: 123, , ABC. I need the output file to retain the quotes around the data.

Is this something that can be corrected in the record map? Or is it an issue elsewhere?

Hi Community,

I am trying to remove a duplicate OBX from a result, but I am running into some issues. Let me explain.

First I had a OBX where the observation Value had the blood type in it and the following OBX had the result in it.

The clients wants the blood type and the result in one field. therefore I merged / concatenated the observation values of the two OBX's.

I tried removing the OBX:2 but just cant take the whole segment out.

please see examples below

This is the result.

I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?
