v2026.1 was just released as GA, and one of the features I'm looking forward to using is the DTL Explainer feature.

This allows you to take a Data Transformation, and with a click of a button get a human-readable description of the transformation (which you can also use as the basis for the DTL Description).

For complex DTLs, especially ones you didn't write yourself, or you did but a long time ago, this will allow you to get a clear quick understanding of what it's doing.

Introduction

FHIR (Fast Healthcare Interoperability Resources) is the modern standard for storing and exchanging clinical data. But once your data is in a FHIR server, how do you actually explore it? FHIR data is stored as JSON — powerful, but not practical to read directly. I wanted a tool where you could click on a patient, see their conditions, medications, lab results, and more — in a clean, readable format. So I built the FHIR Patient Viewer.

How It Works

The app runs entirely in Docker and connects directly to an InterSystems IRIS for Health FHIR server.

Working with files often starts off simple. open the file, read, and process. That approach works perfectly well, until the file happens to be an Excel file.

A Common Assumption

At first, an Excel file (.xlsx) looks like just another data file, rows, columns and values. nothing unusual. So it's natural to assume it can be read the same way as a .txt ot .csv file. But that's where things start to break.

Why Excel files behave differently

The key difference is how the data is stored:

-> .txt / .csv - plain text, line-by-line.

-> .

Hi Guys,

I've connected VS Code to my IRIS server and can see projects & web application option but not Classes tab, how can I add it, and with the old Studio we do have the Inspector tab where we can check properties, Storage, methods, are these available in VS code?

also does any changes or new classes created via VS code automatically reflected in my IRIS namespace ? 

Thanks

Since our previous announcement, we have introduced several incremental improvements to the client‑side editing experience in VS Code. These updates focus on preserving developer‑authored formatting when synchronizing with the server.

What Changed

Client‑side *.cls files previously lost certain formatting details during compilation, including keyword casing (e.g., classmethod → ClassMethod), normalization of blank lines between class members, and removal of line breaks within parameter lists.

The 2023.1.7 maintenance releases of InterSystems IRIS^® data platform,InterSystems IRIS^® for Health^TM, and HealthShare^® Health Connect are now Generally Available (GA). 

Please share your feedback through the Ideas Portal using the category Post-Release Feedback so we can build a better product together.

Hi Community,

Preparing for InterSystems Certification examsrequires more than reading documentation. It calls for focused practice aligned with real exam objectives.If you are planning to validate your expertise in HL7, SQL, System Administration, or Development, structured preparation can make a significant difference.

🧑‍🏫 Exam preparation platform

The platform offers a large pool of practice questions mapped to certification domains, along with detailed answer explanations that point back to relevant documentation.

The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS^® for Health^TM, and HealthShare^® Health Connect is now Generally Available (GA). This is an Extended Maintenance (EM) release.

The Interoperability user interface project has continued from 2025.1 and has incorporated many of the items that you – our customers and partners – have suggested and observed.  We are continuing to invest in feedback and updating this important user experience.  In the latest release, 2026.1 for IRIS, IRIS for Health, Health Connect and Health Connect Cloud, the BPL Editor and Message Viewer/Visual Trace applications are now available for opt-in!
NOTE:

• Existing users can switch between the modernized and standard experiences.

For example in %Library.File Class Documentation,  FiieSet query is listed as: 
"Selects Name As %String, Type As %String, Size As %BigInt, DateCreated As %TimeStamp, DateModified As %TimeStamp, ItemName As %Stringof ..."

How to obtain a "real" syntax?

Thank you.

Hi Guys,

I get a Quit argument not allowed error in an if block how can I fix this?

I have created the following Task to kick off a Ens.BusinessService to execute a SQL query and process the results

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition
{

Parameter TaskName As STRING = "OSU - Workday Termination Update";

Method OnTask() As %Status
{
    #Dim sc as %Status
    #Dim ex as %Exception.AbstractException
    
    set sc = $$$OK

    try{
        // create the service
        #Dim tService As OSU.DataSource.Workday.TermService
        Set tServiceConfigName = "OSU.DataSource.Workday.

Hello, I am working with @Alberto Fuentes https://openexchange.intersystems.com/package/workshop-iris-oauth2.

I wonder how do I get a token to send to the resserver?

I tried calling "token_endpoint" : "https://webserver/authserver/oauth2/token"

The response was "error":"invalid_request","error_description":"Unknown grant_type"

I wonder what needs to be in the request body? Is it a GET or POST?

As you all probably know, Health Connect / IRIS for Health natively supports DICOM messaging, and many of you will have used it daily. Well, I recently discovered a rather insidious little issue that our beloved @Alberto Fuentes gave me the solution.

We (I) will call this phenomenon the Creosote effect (those of you who know Monty Python will understand the reference, for the rest you can see the sketch here )

Mr.

Hi,
I'm pretty sure I'm not the first one to encounter this, so please share your solution
I'm trying to load a package with 2 dependencies, one of them has 5 dependencies..
is there a better tool / script / wizard for that?

The problem

How many times have we migrated an IRIS Instance to another machine, maybe even another version, and after a few days realized we forgot that one SSL Configuration critical for a Business Operations to work? Or maybe a credential, or a lonely class in a package by itself?

The solution

The simple solution is to make a checklist¹. A checklist of the entities we have to move. But simple checklists on Word documents are often forgotten, or just ignored.

I have a json object coming in on a service with a field that has "NaN" as its value.

"ReferralInOutOfNetworkCd": "NaN",

In my DTL, I do a straight copy. yet what goes outbound is NaN, without being wrapped in double quotes

"consulting_provider_network_ordering_rd":NaN,

Has anyone experience this?  If so, did you find a way to fix or work around it?

Hello Community!

We're pleased to invite you to the upcoming webinar in Hebrew:

👉Getting Started with OAuth 2.0 on InterSystems👈

I created a new repo called ipm-module-budget from https://github.com/intersystems-community/intersystems-iris-dev-template template.

I cloned the repo to an EC2 instance in AWS. When I try to build image, I see this error:

#8 22.09 [IRISAPP|ipm-module-budget] Reload START (/home/irisowner/dev/)Segmentation fault (core dumped) #8 ERROR: process "/bin/sh -c pip3 install -r requirements.txt && iris start IRIS && \tiris session IRIS < iris.scri pt && iris stop IRIS quietly" did not complete successfully: exit code: 139

Issue

In the versions specified above, an instance may fail to start or may hang during operation if the database cache is greater than or equal to 2,097,152 MB (2 TB).

Hi Community,

We're super excited to share that we’ve just launched a new free, interactive tutorial designed especially for those who are new to InterSystems IRIS and looking for a clear, practical introduction to its core concepts.

🧑‍🏫 Data Models of InterSystems IRIS 🧑‍💻

There are lessons we learned from developing and maintaining code for interoperability components within a healthcare institutional environment.

The plane is already flying

Be prepared to rebuild, improve, extend, and fix the plane mid-flight.
 

Maintenance windows for hospital systems are often very limited, with some required to be operational 24/7. While the critical health systems such as imaging modalities or registration kiosks — or at least their critical functions — must operate autonomously, efficiency and usability may be compromised when interoperability components malfunction.
