Is there any good documentation/tutorials on creating gateways in both directions between FHIR and Hl7v2 (for Health Connect)?

the scenarios I'm most interested in

1. Client application sends a FHIR demographic query to Health Connect - and the interface has to convert this to Hl7v2 QBP^Q11 message to the PAS.

2. Health connect sends a PDF document (from a file or HL7v2 interface) to an EPR over FHIR.

Thanks

Stephen

Hello,

I have some beginner questions as I am working through the InterSystems Cache learning path:

- Where I work, we us Cache, but we often learning about and train on MUMPS. No one really talks about or mentions MUMPS here, but my understanding is that ObjectScript is basically MUMPS plus whatever new things InterSystems put on top of it. Is that a fair assessment?

Has anyone called any outside Javascript code from inside their class files? I asked a long time ago if there was a way to manipulate an image within Cache Object Script, and since Cache doesn't have any image libraries its not really possible. However I have found Javascript to resize an image and wonder how hard it would be to mesh the two together.

Can anyone share any examples?

Thanks

Scott

Hi -

I'm wondering if anyone has coded up a means to create an extension for a %Persistent class from a base class to a sub-class without making a ton of assumptions about the Global structure. I'm trying to create a new "extension" record that would have the same ID as the Base Class

Class BaseRecord Extends %Persistent

and

Class SubRecord Extends BaseRecord

where I would have an instance of a "BaseRecord" and I want to turn it into a "SubRecord" instance and have all of the existing references to the BaseRecord survive.

The following post outlines an architectural design of intermediate complexity for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings. This post introduces two new databases: the first to store the globals needed for synchronization, the second to store fact tables and indices.

One of the many benefits of using Atelier for your ObjectScript development is its integration with a wide range of source control systems. This integration enables you to use modern development workflows which increase collaboration while minimizing the risk inherent to volatile code bases.

Veteran ObjectScript developers can tell you about the workarounds that were needed before they could use source control systems with products like Caché and Ensemble. One of these was to treat the data store itself effectively as a code repository. And so shared development environments became essential for many of our customers to be productive and successful.

For code shops that rely on shared development environments, adopting Atelier might seem too complicated. This article aims to provide a practical example to guide your team towards success with Atelier.

You can find an overview of the problems and solutions in this article here, which is a good place to start. This article assumes that you are familiar with the concepts introduced there.

There's a new and exciting enhancement to QEWD that has just been released - it's an additional layer of abstraction known as QEWD-Up. QEWD-Up hides away all the mechanics of QEWD itself, allowing you to focus on just your REST APIs and the code that implements them.

Additionally, and importantly, QEWD-Up simplifies the maintenance of your REST APIs, allowing you (and others) to quickly and easily understand their life-cycle and implementation.

Docker-compose default network conflicts

I recently had to diagnose a networking problem I was having when attached to our corporate network. I was seeing an unknown bridge network being defined that shared the same IP address space as the company network thus blocking access to company resources. This bridge network was separate from the Docker0 bridge network which the docker engine sets up. Docker was configured with a bip (bridge ip) address to prevent docker form using an address space that create a conflict.

Use %XML.Node to walk a DOM

The following code walks a DOM using %XML.Node. It also prevents %XML.Writer to change whitespace. Run the code using the class method "test":


Class objectscript.walkDOM Extends %Persistent
{
    ClassMethod dfs(node As %XML.Node)
    {
        s entrynode=node.NodeId
        do {
        //element nodes with one whitespacetyped child are the ones we want to change
        if (node.NodeType=$$$xmlELEMENTNODE){
            s snode=node.NodeId     
            if (node.MoveToFirstChild())            
                {
                    i ('node.MoveToNextSibling()){
                        i (node.NodeType=$$$xmlWHITESPACENODE){
                            s node.NodeType=$$$xmlTEXTNODE
                            s node.NodeId=snode
                        }
                    }
            }
            s node.NodeId=snode     
        }   
        if (node.HasChildNodes()){
            d node.MoveToFirstChild()
            d ..dfs(node)
        }
        } while (node.NodeType'="" && node.MoveToNextSibling())
        s node.NodeId=entrynode
         
    }
     
    ClassMethod test()
    {
      set xml = "abcdefg"
     
      s reader=##class(%XML.Reader).%New()
      do reader.OpenString(xml)  
      set writer = ##class(%XML.Writer).%New()
      //do some magic
      d ..dfs(reader.Document)
       
      w !,"with indent=1:",!
      set writer.Indent = 1
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
      set writer.Indent = 0
      w !,"with indent=0:",!
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
    }
}

How to deal with Large PDF

Hi

We have a few large PDFs coming into our engine - when it goes thru the Process and hits the Data Transformation it gets cut off before it sends it outbound to the receiving system.

Whats the best way to handle large PDFs?

InterSystems products (IRIS, Caché, Ensemble) already include a built-in Apache web server. But the built-in server is designed for the development and administration tasks and thus has certain limitations. Though you may find some useful workarounds for these limitations, the more common approach is to deploy a full-scale web server for your production environment. This article describes how to set up Apache to work with InterSystems products and how to provide HTTPS access. We will be using Ubuntu, but the configuration process is almost the same for all Linux distributions.
