Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

I was really surprised that such a flexible integration platform with a rich toolset specifically for app connections has no out-of-the-box Enterprise Service Bus solution.

I'm trying to access the Bearer token from the Authorization header in my REST service class, but I'm getting a 500 Internal Server Error when I try to use %request.GetCgiEnv("HTTP_AUTHORIZATION").

My Environment:

• InterSystems ensemble 2018
• Using EnsLib.REST.Service with HTTP Inbound Adapter
• REST API URL: http://ip:port/api-kiosk/patientData

My Code:

objectscript

I have a class that extends %CSP.REST which made I deployed using $system.OBJ.MakeClassDeployed. After upgrading IRIS, the web app which uses that class no longer works with an ObjectScript error.

In the past, I fixed that problem by adding a dummy new line or a comment then recompiled that class. For this deployed class, I can't add a new line and recompile the class (the code shows up as locked in Studio). Simply running $system.OBJ.compile() is not fixing the web app issue.

Is there a way to edit a deployed class then recompile it?

If you are in the business of building a robust High Availability, Disaster Recovery or Stamping multiple environments rapidly and in a consistent manner Karmada may just be the engine powering your Cloning Facility.

The default request class, Ens.Request is fine for our initial workflow.

We want to define other workflows that will reuse the same BPL class. These workflows would send messages inbound to the BPL as different request classes.

Is this possible or is it required that we send in a request class matching the context request class in the context tab?

Thank you

Hey Community,

The InterSystems team recently held another monthly Developer Meetup in the AWS Boston office location in the Seaport, breaking our all-time attendance record with over 80 attendees! This meetup was our second time being hosted by our friends at AWS, and the venue was packed with folks excited to learn from our awesome speakers.

Hi,

I am trying to include in my Data Transform, if OBX 5.1 (Observation Value) Contains certain text i.e. DETECTED then populate the Abnormal Flag field with a certain letter.

Sometimes the text can be uppercase, lowercase or a multiple of both.

Any help would be much appreciated.

Thanks

Jason

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?

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?

What are the best practices for choosing a shard key in InterSystems IRIS to ensure long-term scalability without needing major refactoring later?

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!
