Hi,

We have some concerns on how to implement FHIR, do we do facade?, how do we get resources?, what is a resource?, is a resource "Patient" or an instance of a patient?, How can we have a FHIR repository AND send the patient details to healthshare MPI?

Has anyone correctly created a FHIR server that has custom methods?, handles "normal" methods and forwards onto Healthshare MPI , processing the response and creates a accurate FHIR response back to the calling system.

We require automatic injection of security predicates at runtime, depending on the user or API token. Is there a supported or hackable mechanism to manipulate SQL parsing/compilation before execution?

Hello Community,

When I compile the Sample.User class for the first time, and include an ObjectGenerator method intended to run certain logic during each compilation, it throws a <CLASS DOES NOT EXIST> error. However, recompiling the same class works as expected.

I understand this happens because the class hasn’t been fully compiled yet during the first pass. To overcome this issue, are there any specific callback methods available that can safely be used after the class is fully compiled?

InterSystems IRIS Community Edition HAOS Add-On

Run InterSystems IRIS inside of Home Assistant, as an add-on. Before you dismiss this article possibly under the guise that this is just a gimmick, Id like you to step back and take a look at how easy it is to launch IRIS based applications using this platform. If you look at Open Exchange, you will see dozens of dozens of applications worthy of launching while they are basically hung out to dry as gitware, and launchable if you want to get into a laptop battle with containerd or Docker. With a simple git repo, and a specification, you can now build your app on IRIS, and make it launchable through a marketplace with limited hassle to your end users. Run it along side Ollama and the LLM/LAM implementations, expose anything in IRIS as a sensor or expose an endpoint for interaction in your IRIS app to interact with anything you've connected to HAOS. Wanna restart an IRIS production with a flick of a physical switch or Assisted AI? You can do it with this add-on, or your own, right alongside the home automation hackers.

I need to build an integration solution that reads messages from a Kafka topic. The topic has 3 partitions and contains several million messages.

For certain reasons, I can only use the standard EnsLib.Kafka.Service class and cannot use either KafkaClient or Python.

The built-in %JSONExport() fails with circular references in deeply nested objects. How can I write a custom serializer that supports circular detection and reference tracking?

Not sure where to ask for some helpful hints about IRIS 2019.1 in 2025, but here goes.

I'm trying to create a new Java gateway to run some Java code through ObjectScript, but I keep getting an error saying "Java executable not found in the given directory":

This is my Object Gateway Server definition:

Introduction

In a previous article, I presented the IRIStool module, which seamlessly integrates the pandas Python library with the IRIS database. Now, I'm explaining how we can use IRIStool to leverage InterSystems IRIS as a foundation for intelligent, semantic search over healthcare data in FHIR format.

This article covers what I did to create the database for another of my projects, the FHIR Data Explorer. Both projects are candidates in the current InterSystems contest, so please vote for them if you find them useful.

You can find them at the Open Exchange:

• IRIStool and Data Manager
• FHIR Data Explorer

In this article we'll cover:

• Connecting to InterSystems IRIS database through Python
• Creating a FHIR-ready database schema
• Importing FHIR data with vector embeddings for semantic search

Hi all,

Recently we were experimenting with having a variable target on a routing rule and noticed some interesting behaviour, code below.

Introduction

In my previous article, I introduced the FHIR Data Explorer, a proof-of-concept application that connects InterSystems IRIS, Python, and Ollama to enable semantic search and visualization over healthcare data in FHIR format, a project currently participating in the InterSystems External Language Contest.

In this follow-up, we’ll see how I integrated Ollama for generating patient history summaries directly from structured FHIR data stored in IRIS, using lightweight local language models (LLMs) such as Llama 3.2:1B or Gemma 2:2B.

The goal was to build a completely local AI pipeline that can extract, format, and narrate patient histories while keeping data private and under full control.

All patient data used in this demo comes from FHIR bundles, which were parsed and loaded into IRIS via the IRIStool module. This approach makes it straightforward to query, transform, and vectorize healthcare data using familiar pandas operations in Python. If you’re curious about how I built this integration, check out my previous article Building a FHIR Vector Repository with InterSystems IRIS and Python through the IRIStool module.

Both IRIStool and FHIR Data Explorer are available on the InterSystems Open Exchange — and part of my contest submissions. If you find them useful, please consider voting for them!

To manage the accumulation of production data, InterSystems IRIS enables users to manage the database size by periodically purging the data. This purge can apply to messages, logs, business processes, and managed alerts.

Please check the documentation for more details on the settings of the purge task:

Hi,

I have the following transform working but i also want to add another string of text for it to look for but i'm unsure of how to write this in. The two bits of text are "NOT DECTECTED" and "Negative"

Hi,

I'd like to report a really strange behavior of the Intersystems Lite Terminal after executing a simple ObjectScript instruction.

From the Intersystems Lite terminal, execute the following instructions:

- Set uniqueId = "12345678_1"
- Set uniqueId = $p(uniqueId,"_",1)_"_"_($p(uniqueId,"_",*)+1)
After executing the second instruction, the terminal closes without any error.

We want to expose both REST and GraphQL endpoints over the same data models. Is there a way to implement or integrate GraphQL with ObjectScript and map to class methods?
