Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite
select top 10 ID from some_table where row_status in ('I','U') order by ID - the same
select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I asked Gemini and it recommended me rewrite the query as

In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Hi Community!

We’re excited to announce the launch of a new, hands-on training program:

🧑‍💻 Developing FHIR Applications Using Python 🧑‍💻

This cohort-based course takes developers from FHIR fundamentals to advanced, real-world healthcare interoperability solutions, with deeper, more practical coverage than typical industry offerings and a strong focus on production-ready skills using InterSystems technology.

Hey everyone,

I'm just seeking some guidance and confirmation on what I'm doing for my production health monitoring.

We utilize Grafana to have reporting/monitoring dashboards and I have made a REST API to query the health of our productions. I believe I have everything figured out except for one thing that I'm uncertain about and that is the Production Item Color indicators:

Hello, I am trying to get some fields from HL7 message and create a file using BPL. The values I need are in a repeating segment (AIG). Even in the repeating segment, I just want the iteration that has a certain field (AIG:3 populated). With the help of documentation and community posts, I was able to create the BPL to loop through all of AIG and create the file. But when I try to narrow the results even further (AIG:3 present), the process gets stuck. I am not sure I am missing anything or have anything incorrectly set up. Also, since the process gets stuck, it doesn't even seem to h

Hi,

I want to consume an API that provides HL7 messages. To achieve this, I have thought of the following workflow:

I have created a business service that periodically triggers a business process. The trigger request is forwarded to a business operation. There, a %Net.HttpRequest is assembled from scratch and then sent to the API endpoint. The corresponding HttpResponse then contains several HL7 messages encoded in UTF-8 in the message body. To further process the HL7 messages, the operation sends the HttpResponse back to the business process as EnsLib.HTTP.GenericMessage.

I have always struggled with Iterating through a JSON response to pull out certain fields into a Data Class Structure to use to populate fields in a DTL. So I defined the whole structure for the following JSON, with the base structure extending Ens.Response, %XML.Adaptor, and %JSON.Adaptor.

TL;DR This article explains how to deploy InterSystems IRIS Community Edition on Azure using the Azure Marketplace and a Virtual Machine. It covers prerequisites, instance selection, authentication, SSH access, first verification steps, and how to delete resources to avoid charges. The deployment can typically be done using Azure free credits and is suitable for developers who want to quickly start working with IRIS in the cloud.

Who this guide is for. This guide is intended for developers, solution architects, and DevOps engineers who want to deploy InterSystems IRIS Community Edition on Microsoft Azure. No prior Azure automation experience is required, but basic familiarity with the Azure Portal and SSH is helpful.

After following this guide, you will be able to:

  • Launch InterSystems IRIS Community Edition from the Azure Marketplace
  • Configure a small, secure Azure VM
  • Connect to IRIS using SSH and the Management Portal
  • Reset the default IRIS password and verify that IRIS is running

Prerequisites

  • An active Azure subscription (new accounts may have free credits)
  • Permissions to create resource groups, VMs, and networking resources
  • An SSH client and a private key (.pem) you can store securely
  • Basic knowledge of Linux command line

Deployment overview

  • Open the IRIS Community Edition listing in Azure Marketplace and click Get it now
  • In Azure Portal, choose Start with a pre-set configuration (or Create)
  • Configure Basics: subscription, resource group, VM name, region, image, and size (a small VM is usually sufficient)
  • Choose SSH key authentication and generate/download the key if needed
  • Review + Create, accept terms, and deploy; then Go to resource → Connect → SSH
  • First SSH login: run iris password to change _SYSTEM/SYS; start a session with iris session iris
  • Management Portal: http://YOUR_VM_IP:52773/csp/sys/UtilHome.csp

10:47 AM — Jose Garcia's creatinine test results arrive at the hospital FHIR server.
2.1 mg/dL — a 35% increase from last month.

What happens next?

  • Most systems: ❌ The result sits in a queue until a clinician reviews it manually — hours or days later.
  • This system: 👍 An AI agent evaluates the trend, consults clinical guidelines, and generates evidence-based recommendations — in seconds, automatically.

No chatbot. No manual prompts. No black-box reasoning.

This is event-driven clinical decision support with full explainability:

image

✅ Triggered automatically by FHIR events
✅ Multi-agent reasoning (context, guidelines, recommendations)
✅ Complete audit trail in SQL (every decision, every evidence source)
✅ FHIR-native outputs (DiagnosticReport published to server)

Built with:
- InterSystems IRIS for Health — Orchestration, FHIR, persistence, vector search
- CrewAI — Multi-agent framework for structured reasoning

You'll learn: 🖋️ How to orchestrate agentic AI workflows within production-grade interoperability systems — and why explainability matters more than accuracy alone.

How many times have you had to receive or generate a JSON and wished you could work on it using DTLs without having to deal with DynamicObjects trying to remember the name of each field? Do you want to break down and make your giant JSON file more digestible?

In my case, never, but I thought that someone might find it useful to have a feature that captures your JSON and breaks it down into a series of ObjectScript classes that you can work with more easily and conveniently.

Well then...behold JSON2Class in all its glory!

A question that quickly arises when configuring IAM (aka Kong Gateway) is how many routes should be created to reach all the business objects in an IRIS API.

A common mistake is to create one route per business object, unnecessarily multiplying the number of routes.

Let's take the example of the Supply Chain Orchestrator Data Model API:
