⏯️ 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.

I am connecting to an intersystems cache database via C# and I need to obtain a list of all available namespaces.

I am using code like this:

The George James Software team is looking forward to going to National Harbor for READY 2026!

As part of the conference, we'll be hosting our Deltanji Source Control User Group:

Date: Wednesday, April 29th 
Time: 8 - 9am (breakfast will be provided) 
Location: Azalea 1 
RSVP by emailing laurelj@georgejames.com. 

We'll be showing what will be included in the next release of Deltanji, version 8.2, as well as providing an opportunity for questions and discussion. We welcome both current and prospective users to join us.

Hi Community,

Can't make it to the National Harbor in person? You can still be part of READY 2026 — two streams will be going live during the event.

Hey Community,

We’re launching a new initiative in which ideas from the Ideas Portal become real applications on Open Exchange, and their authors are rewarded through Global Masters:

💡 Community Bounty Program “Idea to Application” ⚙️

The Management Portal doesn't have a native way to switch to Dark Mode. This can be resolved using a Chrome extension called Dark Reader. See the result:

To install and use the Dark Reader:

1. Go to https://chromewebstore.google.com/detail/dark-reader/eimadpbcbfnmbkopoojfekhnkhdbieeh?hl=en

2. Click Add to Chrome

3. Go to your Management Portal and see the results.

4. To toggle (enable and disable) the Dark Mode to the current website use Shift + Alt + D.

5. To configure the Dark Reader, go to the Extensions > Dark Reader > and tiple elipses button:

Enjoy this tip! 

I'm starting to play more with AI enabled coding. 
I've been using Github Copilot inside Visual studio code, which is very good at coming up with autocomplete suggestions that are accurate and useful. (Along with some utter rubbish, naturally).
For web development I'm starting to use Claude Code in VS Code to help create web sites and integrations. I want to see how it can help with IRIS development. 

However I can't get claude to read any iris code directly as I'm connected to my server via isfs server connections.

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

• %-variables (process variables). Reusing only in the same process
• Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

• Using Interoperability Production.

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<>.

Hi Guys,

I've this Business operation pointing to my DSN as below 

where its calling the this method, but for some reason its not recognizing Ens.Util.LookupTable class   

What is a Microservice?

A microservice is an architectural style that structures an application as a collection of small, autonomous services. Each component is developed around a specific business capability, can be deployed independently, and is typically managed by a miniature, specialized, self-governing team. (Source: https://microservices.io/)

During my work with customers and also following I often met the 
explicit or embedded question: What is this "GLOBALS" ?
I'll try to explain the history to unfold the context.

Has anyone done this successfully?  Customer wants to receive HL7 data over https using OAUTH 2.0 client credentials.  I am assuming a custom Operation will be needed?  I tried using CoPilot for assistance but was unsuccessful.  I am not great with Object script :( 

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh

⏯️ AI Assistants for the Unified Care Record Powered by Gemini

In this demo, you will see how Gemini works directly with FHIR data, and how it leverages the harmonized dataset provided by InterSystems Unified Care Record. It also showcases multiple AI assistants helping multiple groups of users, e.g. clinicians, patients.
