I've seen that %JSON.Adaptor makes it easy to serialize and deserialize objects to JSON, but I've also seen people building custom serialization logic. Are there scenarios where %JSON.Adaptor falls short, such as handling nested objects, null values or custom field naming conventions? What has been your experience?

Hi folks!

Suppose a new version of your amazing software solution built on IRIS needs some persistence change: some data needs to be converted, some classes get new properties or even renamed, and some data should be prepopulated for newly introduced persistent classes to keep the whole application data consistent.

What are your approaches? 

SQL-based scripts? ObjectScript, or Python? for both directions of migration, up and down? 

Do you autogenerate it with Claude/Codex? What about data-consistency tests?

COuld you please share your thoughts? or libraries?

Hi Developers,

We are happy to announce the new InterSystems online programming contest:

🏆 InterSystems Programming Contest: AI Agents for FHIR🏆

Duration: May 25 - June 14, 2026

Prize pool: $12,000

Healthcare billing isn’t a pipeline. It’s a conversation about trust. 

Every day, millions of clinical transactions flow from doctors’ keyboards to insurance ledgers. Standard health IT systems are built to count these transactions. They store them. They organize them. 

They route them. But standard systems don't notice them. 

We’ve built faster and faster databases to process claims, but we forgot to ask: Does this claim make sense? 

Because we don’t ask in real-time, we’ve accepted a compromise. We pay first, wait six months, and then hire forensic auditors to find the mistakes.

I know IRIS has a built-in testing framework, but I'm not sure how to write tests that validate the full message flow through a Production without depending on external systems. Do you mock Business Operations? Is there a pattern you use to test integration scenarios in an isolated and repeatable way?

If I need to add or change properties in a message class that is already being used by a running Production, what is the safest way to do this? Are there risks with existing messages in the queue or in the message store? Is there a migration strategy the community recommends?

I understand that Business Rules can be used to route or transform messages without touching code. But I'm not clear on when it's better to use a Business Rule versus handling the logic directly inside a BPL or a custom BP class. What criteria do you use to decide between them?

In .NET projects I usually rely on appsettings per environment. In IRIS Productions, settings are stored per component and seem tied to the namespace. What strategies do you use to manage different configurations across environments without manually changing settings every time you promote a Production?

Hi Community,

We're excited to invite you to the upcoming webinar: 

👉 Can FHIR also serve as input for operational management? 👈

🗓️ Date & Time: Wednesday, June 10th, 10 am CEST

In the previous article, we used pyprod to create production components while relying on the UI for production configuration. That same production can now be defined entirely in Python:

from intersystems_pyprod import Production, ServiceItem, ProcessItem, OperationItem

iris_package_name = "HelloWorld"

class MyProduction(Production):
    services = [
        ServiceItem(
            "MyServiceName",
            "HelloWorld.MyService",
            host_settings={"target": "MyProcessName"},
        )
    ]
    processes = [
        ProcessItem(
            "MyProcessName",
            "HelloWorld.MyProcess",
            host_settings={"target": "MyOperationName"},
        )
    ]
    operations = [
        OperationItem("MyOperationName", "HelloWorld.MyOperation")
    ]

An engineering walkthrough of the IRIS-CardioFlow project architecture with real code for its AI, FHIR, and connectivity layers and the role of iris-agentic-dev in a modern ObjectScript workflow.

Introduction

Monitoring cardiovascular surgical flow in real time is a classic healthcare integration problem: data arrives from heterogeneous sources, must be persisted with clinical semantics, exposed through an API, and presented in a way the care team can act on. The CardioIris repository (internally named IRIS-CardioFlow) is a lean demonstration of that scenario, built on InterSystems IRIS 2026.

Hi all,

I'm working on a DICOM router in InterSystems IRIS, based on the workshop-iris-dicom-interop (https://github.com/intersystems-ib/workshop-iris-dicom-interop) example on GitHub. I'm using EnsLib.DICOM.Process to route incoming images to different PACS destinations, where the target system is decided at runtime via a database lookup.

I've run into two issues I'd love some guidance on:

1. Dynamically changing the destination without disrupting transactions

Right now, if I want to send to a new PACS target, I'd need to add a new Business Operation and call

In the previous IoP article, I showed how IoP can expose Python messages to DTL by generating JSON schemas. That is useful when the message is primarily a Python object and we want the IRIS tooling to understand its structure.

This time, the direction is a little different.

Starting with IoP 3.7.1, a PersistentMessage can now be a native IRIS message body class. The Python class is still the source code you write, but the generated IRIS class extends Ens.MessageBody

IPM version 0.10.7 was released on May 29th, 2026. As usual, you can check it out on the GitHub page or through the Community Registry.

Highlighted Features

Utility Scripts iriscli and ipm

IPM is now bundled with two convenience scripts that are runnable from a standard terminal. iriscli launches an interactive IRIS terminal and runs IPM commands directly. These are automatically installed to both ~/.local/bin/ and , so they work inside and outside of containers (Unix/Linux only).

Examples:

I have several Business Operations that share similar behavior, like building HTTP headers or parsing a specific response format. In C# I would extract this into a service class or a base class. What is the recommended way to do this in IRIS? Should I use a utility class, a common superclass, or is there another pattern the community prefers?

I have a Business Process that needs to call an external API that may take several seconds to respond. I'm worried that keeping the BP blocked waiting for the response could affect the overall Production throughput. Is there a recommended pattern for handling async calls inside a BPL or custom BP class to avoid this kind of bottleneck?

Hey everyone.

My team and I have a rare opportunity to start from scratch, and I am keen to know what things others that have gone through a similar process did differently. Obviously there's the immediate benefit of losing any technical debt that has built up over 10+ years of an ever changing environment along with many organisational changes and merges, but I'm thinking about the things that we can do to make life a lot easier for the next 10+ years.

Hi, we are trying to adapt the solution to use the IKO but we have problems deploying the webgateway on our company clusters, our clusters requires to have a specific definition on the securityContext due security concerns, it's possible to set those values trough the IrisCluster CRD? or we cannot use it from it? Should I open a WRC to handle this?

create Pod iris-webgateway-0 in StatefulSet iris-webgateway failed error: pods "iris-webgateway-0" is forbidden: ValidatingAdmissionPolicy 'prevent-root-run' with binding 'prevent-root-run' denied request: Containers should run with securityContext.runAsNonRoot or securityContext.runAsUser != 0.

I'm approaching the need to send notifications through a Microsoft Exchange or Gmail servers. however my last foray into this, I was blocked due to an issue inside my SSL certificate is what I thought after the attempt.

So my attention will be on trying to match the cryptography in the SSL certificate I produce compared to the mail server I'm trying to use.

Has anyone else had an issue with this approach? My other option is Amazon SNS potentially. I do have a functional MS Teams channel for alerts, and can make different notification channels as well.

Any help or insights are appreciated.
