Hi everyone,

I’m thrilled to share that after several years of deep diving into the InterSystems IRIS data platform, I have finally summarized my project experiences into a new book: "IRIS (Data Platform) Programming Technical Guide" (published by Beihang University Press).

Writing this book was a significant engineering challenge for me. My goal was to bridge the gap between "understanding the syntax" and "building a production-ready project.

Hello, community.

I've been working with Intersystem Caché for two years, and right away I was excited about the rich ecosystem that Caché provides. However, I was disappointed with calls using #call, and I understand that it was a limitation of the time. Well, the frustration is that #call returns null by default, meaning an AJAX request is executed, but there's no hook to retrieve the return from that request. The only way to retrieve the data from that request is by building a callback on the server side using &js<>.

⏯️ Health Galaxy: AI-Enabling Healthcare Applications

Health Galaxy creates an AI access point on top of any FHIR server, bringing healthcare into the AI future that has become a reality for many other industries. 

• AI access: Health Galaxy gives AI agents a single gateway into any healthcare system, so they can pull patient data, schedule appointments, and check insurance automatically instead of a human doing it manually. 
• Ease of use: You point it at an existing FHIR endpoint, click a button, and it generates an MCP endpoint automatically from the capability statement. 
• FHIR: Since we are using FHIR, we can leverage both the storage and exchange capabilities of InterSystems IRIS.

⏯️ HL7 Validation Error Profiler: Rapid Insights into Batch HL7 Data Quality Issues

This demo highlights how HL7 validation logs can be transformed into scalable, actionable data quality insights using a lightweight application built on top of Health Connect.

• Batch ingestion and parsing of HL7 validation error logs into structured data
• Aggregation of errors by segment, field, and type to reveal systemic issues
• Interactive dashboard (Streamlit) for filtering, exploration, and root cause analysis
• Rapid identification of top error patterns across entire data feeds
• Natural language chatbot for intent-driven data investigation and querying
• PDF report generation for sharing clear, evidence-based feedback during data source onboarding 

Special thanks to @Henry Wojnicki for his contributions to designing and refining the application workflow.

Introduction

In healthcare interoperability environments, InterSystems Health Connect typically contains critical components such as productions, business processes, operations, services, utility classes, routines, and other ObjectScript artifacts. Traditionally, many deployments of these components have been done manually, by copying classes, importing XML, or using administrative tools from the management portal.

In our previous article, we explored the basics of unit testing in IRIS and the ways to apply it to a REST API. We even figured out how to test logic before finalizing network configurations and authentication, allowing us to focus solely on testing the API contents. Today, we will build upon that foundation and elevate our unit testing strategy by using another tool: %Populate .

At first glance, the %Populate class appears to be very simple. You can create a class that extends both %Persistent and %Populate and inherit a Populate method designed to generate randomized records.

For those of you that weren't at READY last week, you may have missed the exciting announcement that the Early Access Program for AI Hub is officially open. It was announced during an amazing demo from @Benjamin De Boe and @Jeff Fried, I recommend catching up with this demo when the recording is released!  I had the opportunity to play with AI Hub in advance, and thought I might share an introduction with the community.

Hi everyone,

I'm working on a requirement to generate and export medical reports to PDF using Logi Reports. The core requirement is that each generated PDF must be encrypted (password-protected), and the password needs to be dynamically set to the specific Patient's Date of Birth (DOB).

Currently, the report is populated using a Stored Procedure as its data source.

My questions are:

1. Is there a built-in way or API in Logi Reports to dynamically set the PDF export password using a field returned from my dataset (e.g., taking the Patient_DOB column from the Stored Procedure)?

⏯️ AI-Assisted Rare and Complex Disease Detection

This demo shows how InterSystems Health Gateway can be used to pull in outside patient records from networks like Carequality, CommonWell, and eHealth Exchange, creating a more complete longitudinal view in a clinical viewer. That full record is then analyzed by AI to surface potential rare disease considerations with clear reasoning, helping clinicians see patterns they might otherwise miss.

Hello everyone,

The Certification Team of InterSystems Learning Services is excited to announce the release of our new InterSystems IRIS SQL Professional exam. It is now available for purchase and scheduling in the InterSystems exam catalog. This exam is geared towards IRIS SQL experts, and it deals with a variety of advanced IRIS SQL topics that you can find in the exam page.

Hi Everyone,

We are looking for a way to disable production Business Services concurrently so that the whole process takes shorter amount time than just going sequentially in a loop and disable them one at a time (very slow). This is necessary for us to be able to stop all traffic to IRIS so that no data remains after we perform full production stop. 

Thank you!   

Introduction

Today, coding assistants like Claude, GitHub Copilot and Cursor have transformed the way developers write code. However, these tools are limited by being isolated from the systems and data sources that developers work with daily. This limitation can be overcome through the Model Context Protocol (MCP), an open standard designed to connect AI assistants to external data sources and tools in a secure and standardized way.

In this review article, we'll explore the current state-of-the-art regarding the MCP within the InterSystems ecosystem.

Okay… first things first - sorry it took me so long to write this up. There was just too much happening, too many conversations, too many photos, too much travel and honestly… too much excitement to sit down and write right away.

READY 2026 started the way it always does, with that unique mix of anticipation and energy in the room. Look at these excited faces!

Hi,

I'm trying to run an SQL against Backup.Task table.

There is this class:

Class Backup.Task

documented here:

Hi Guys,

I've the below code to build JSON and send it via httpRequest called from business Operation.

But I'm getting this error, which I'm guessing that the formulated JSON doesn't have the correct format, so I was looking to convert the JSONStream to JSON string and try to validate it so see where the JSON is broken, problem is that I'm expecting that there will thousands of records in this JSON so it will hard to go through it, so is there a way to track for error or why this JSON is failing to send    

Thanks

How can I remove UNIQUE NOT NULL from an existing column via DDL?

I currently have a table in production that was originally created via DDL, where the column was defined as UNIQUE NOT NULL:

CREATE TABLE database.Books ( ID %Library.UniqueIdentifier PRIMARY KEY, TagExternal VARCHAR('') UNIQUE NOT NULL,  

I now need to change this column so that it is no longer UNIQUE and no longer NOT NULL, making it equivalent to:

TagExternal VARCHAR(''),

As promised, here comes the second part.

But before I begin, here's the view from my hotel window in Boston, where I went before the READY. And a grand building on the right is the office of InterSystems. Not bad, ha?

Anyway, after getting some sleep after the Demos and Drinks the day before, we were back at it the next day, which started with more keynotes.

Was wondering if anyone had a Dynamic way to see if a Global is still being used by a Class File. 

We have been monitoring our Global Size recently, and I am trying to find problematic Class files that are not being cleaned up or used appropriately. I have come across some globals that do not seem to have a Class attached to them anymore, and instead of deleting globals 1 by 1, I was looking for a way that we could dynamically do this since the globals have data that is stale in them.

Thanks

Hi! 
We are working on containerizing our IRIS product. We want to extract the message log that is shown in the terminal, but if possible, we want to format the output as JSON and include some extra fields from the instance to enhance our monitoring. Is this possible?
Any guide or example about it?
Thanks!

I have a question around mapping between different datasets during the HL7 -> SDA3 -> FHIR transformation.

We have a FHIR server which uses the standard ISC HL7->SDA3->FHIR conversion when ingesting HL7 messages. There is the odd requirement to enrich FHIR data from the original HL7 message. due to site specific HL7. Our approach is to extend HS.Gateway.HL7.HL7ToSDA3 with a custom GetSDA method that includes the original HL7 Message ID via CustomPairs.

Abstract

Solar irradiance forecasting is critical for grid stability in photovoltaic (PV) power plants. This article replicates and extends the methodology of Lara-Benítez et al. (2023) "Short-term solar irradiance forecasting in streaming with deep learning" replacing the original offline simulation with a fully operational streaming pipeline built on InterSystems IRIS. We leverage IRIS Interoperability Productions as the streaming backbone, Embedded Python to run MLP, LSTM, and CNN deep learning models, and IntegratedML as an AutoML baseline.

This article introduces SHAP explainability methods as an approach to understand the reasons behind predictions in machine learning black-box models. It also includes a simple Jupyter notebook that you can use and modify to gain hands-on experience with these concepts:

We will leverage these concepts for a future implementation in our Continuous Training Pipeline: https://community.intersystems.com/post/complementing-iris-mlflow-continuous-training-ct-pipeline

When managing critical healthcare data through an integration engine you want to know the moment a queue starts backing up or a service drops. 

Unfortunately, this usually leads to an email inbox stuffed full of notifications that can sometimes seem impossible to maintain.

Well, I’ve not solved that problem. 

But I have created something that could help...
