JWT enabled FHIR Server web app access

Hello Community,

I've configured a FHIR Server in FHIR Configuration "/csp/healthshare/learn1/fhir/r4 " and I enabled a JWT Authentication for this web application. I've invoked this url http://localhost:52773/csp/healthshare/learn1/fhir/r4/login with basic auth get the JWT token. Now I use the access token as a "Bearer" for GET the patient resource. But I got 401Unauthorized error. Anyway I can get the patient resource with basic auth. I tired assign with %ALL role for testing as well. Did I miss any additional configuration in "FHIR Server Configuration"

How to change the special variable $ZTIMESTAMP to your local time zone

InterSystems FAQ rubric

$ZTIMESTAMP returns the date and time in UTC format, so to change it to the local time zone, use the following system method: 

$SYSTEM.Util.UTCtoLocalWithZTIMEZONE($ZTIMESTAMP)

The above output will be in the format ddddd,sssss.fff.

    ddddd: Same format as $HOROLOG dates
　sssss: An integer indicating the number of seconds elapsed since midnight on the current date
　fff: Variable number of digits indicating the fractional part of a second

* Similar to $HOROLOG, except that $HOROLOG does not include fractional seconds.

How to find your imported XSD file

Have you ever imported an XML schema from an XSD file? You might want to look at the original file again sometime later, but forgot where you put it.

Do not worry, that information is being kept as part of the import process.

The whole imported XSD schema is being kept in the ^EnsEDI.XML.Schema global. That global holds all the imported XSDs in your namespace. The first subscript is the name of the schema that you see in the portal.

To look for the source XSD file location, simply look at the following place:

^EnsEDI.XML.Schema(<schema name>,"src",1)

For example:

ZW^EnsEDI.XML.Schema("PatMedData"

Testing XML input to Router Management Portal or via XML document viewer

Trying to test a router that takes an XML input and performs a transform on it.
First attempt I tried to test the transform using the XML Document Viewer via the Ensemble -> Interoperate -> XML Document Viewer menu. The transform itself is working however I can not get the output to save to a file. I've made sure permissions are set correctly on the file. It simply doesn't output anything and I'm at a loss as to why.
As another method I also tried testing via Ensemble -> Test -> Business Hosts.Putting the file path/name as the source does not send any data.

Help Needed: Empty Bundle When Converting CCDA to FHIR in InterSystems IRIS

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Looking for examples of creating RESTful JSON web service as "Business service" and converting the JSON data received to a HL-7 message in a Transformation.

HI,

I'm migration an existing integration to InterSystems.  The upstream (external) system calls a JSON web service hosted in the interface engine, which converts the JSON data received to a HL-7 messages to send to the downstream system. I'm looking for direction and example of how to do the equivalent in InterSystems, so the the upstream system only has to modify the URL of the web service they call.

I suppose in IS we'll need to create a business service that is a RESTful JSON web service? How to access the JSON data (parameters in the web service call) in the Transformation?

Thank you!

Best Practice Question - Connecting to REST API's outside of the network

Up until recently, I have been toying around with REST/FHIR capabilities but only internally. Now I have a request to make REST API calls outside of our Network. 

I am using an RSA 4096 key, because Microsoft Active Directory Services which generates the signed certificate could not handle the Elliptical Key (ECC) when I put the request in.

  • Others in the Healthcare industry, how have you handled this when there isn't an API manager involved?
  • Do you connect directly through the Interoperability Engine using a TLS key?
  • How have you ensured that the TLS is enough to keep it secure and not

Old mumps code debugging with vscode

Hi in mumps, we have B "S".  This way one can step command by command.  How can we do this with vscode?  F10 only step to the next line.

Say, if I have a line like

S A=1 S B=2 S C=A+B

I cannot step within the line.  But with "S", one can.

Do you have any idea?

Thanks,

How to interpret FHIR.Interop.Response into Patient FHIR Bundle to use to enhance HL7 message

IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) Tue Apr 30 2024 16:06:39 EDT [HealthConnect:7.2.0-1.r1]

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

This MS SQL Visit Database was built over 20 years ago and is quite cumbersome to keep maintaining.

Git for Shared Development Environments

If you're building solutions on IRIS and want to use Git, that's great! Just use VSCode with a local git repo and push your changes out to the server - it's that easy.

But what if:

  • You're collaborating with other developers on a shared, remote development environment and want to avoid concurrent editing of the same file
  • You're using editors based in the management portal for BPL, DTL, pivots, dashboards, etc. and want straightforward source control for your work
  • You're still using Studio for some things and/or occasionally jump back there from VSCode - or, your team has not yet fully

You can use the List query of the %SYS.Audit to output audit logs programmatically.

The sample code is as follows:

Set statement=##class(%SQL.Statement).%New()  
 Set status=statement.%PrepareClassQuery("%SYS.Audit","List")
 Set rs=statement.%Execute()  
 Set tab = $char(9)

Special thanks to Alvin Ryanputra as his package iris-vector-search that was the base
of inspiration and the source for test data.
My package is based on IRIS 2024.1 release and requires attention to your processor capabilities.

VS Code client-side editing and class/package changes

When using VS Code client-side editing in combination with a file-based revision control system such as git, I find activities such as branch switching and moving/renaming classes and packages a bit tedious, since you to maintain the connected namespace in sync manually.
I am not aware of a built-in way to do this with VS Code Extension. Just added an idea to the portal that is about adding some kind of mechanism to do this automatically, please do not hesitate to comment, amend and vote for idea DPI-I-608  😊

Finding the Inode value for a file

The SYS.Mirror CatchupDB() method requires a System File Number/Inode value as a parameter.   I have not yet found a suitable internal method to get this value.  Is anyone aware of a utility method that would do this?   I do know I can get this value with a small amount of Python or by calling out to the OS.  However I wanted to stick with pure Objectscript in this project if possible.  

Failing in this I will use embedded python to run the line or two of Python needed to get this value.

Thank you for any hints

How to pass the cloned-object from one rule to another, and send the modified object to target Process or Operation in Rule Editor?

Each DTL calls “ConstructClone” to make a copy of the message before making any changes to it. There will be hundreds of cloned-objects in case of hundreds of DTLs

It is expected to run the rules chain by using Rule Editor without DTL, namely against a SINGLE cloned-object (for example HL7 2.3, ORU_R01) with a FunctionSet in case of hundreds or thousand of rules under same protocol

Question is how to pass the cloned-object from one rule 1 to rule 2, and send the modified object to target Process or Operation in Rule Editor?

SQL DatePart Not Working With ISO 8601 Formatted Date & Time

Given a properly formatted ISO 8601 date time of 2024-06-23T06:03:00Z using SQL DatePart results in an error:

  [%msg: <Invalid input to DATEPART() function: datepart='ss', datetime value='2024-06-23T06:03:00Z')>]

If I remove the trailing Z (for Zulu / UTC time) and leave the T, DatePart works fine.

I have also tried various ± offsets from UTC e.g. +0400 and that also results in the same SQL error

I can Trim the trailing "Z", but I would hope that DatePart would work with an acceptably formatted ISO 8601 date time string without having to go through the

Thanks for reading this question.

We need to remove the line feeds and carriage returns from start and end, but not from the middle of a string

We have tested the following ways:

set output = $ZStrip("[line feed](carriage return) str [line feed](carriage return) ing [line feed](carriage return)","<>C")

But it removes also control characters which we need to preserve...

Also we have tested:
