In healthcare, interoperability is the ability of different information technology systems and software applications to communicate, exchange data, and use the information that has been exchanged.
Using embedded Python while building your InterSystems-based solution can add very powerful and deep capabilities to your toolbox.
I'd like to share one sample use-case I encountered - enabling a CDC (Change Data Capture) for a mongoDB Collection - capturing those changes, digesting them through an Interoperability flow, and eventually updating an EMR via a REST API.
Hello everyone
For those interested, here is an implementation example I used in one of my projects to interoperate with MongoDB using the pymongo package.
Interoperates with MongoDB (via pymongo package) with InterSystems IRIS (including outbound adapter)
Remember to import pymongo package.
implementation example for testing here
NAMESPACE> do ##class(custom.python.pymongo.test).TestMongoDBCrud()
for interoperability, use the following adapter in your business operation:
Parameter ADAPTER = "custom.python.pymongo.outboundAdapter";
Parameter INVOCATION = "Queue";
Query example:
FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.
Dear community, we are building up a digital backbone for our 17 hospitals and looking for reinforcement within the team. Maybe this is something for you or someone you know?

The world of Generative AI has been pretty inescapable for a while, commercial models running on paid Cloud instances are everywhere. With your data stored securely on-prem in IRIS, it might seem daunting to start getting the benefit of experimentation with Large Language Models without having to navigate a minefield of Governance and rapidly evolving API documentation. If only there was a way to bring an LLM to IRIS, preferably in a very small code footprint....
Interoperability of systems ensures smooth workflow and management of data in today's connected digital world. InterSystems IRIS extends interoperability a notch higher with its Embedded Python feature, which lets developers seamlessly integrate Python scripts into the IRIS components, like services, operations, and custom functions.
Hello,
Very much keen if we could gather the per namespace and business component utilization of InterSystems cache server.
For e. I have a PRD server where its CPU utilization is at max all the time and I want to know which namespace and its business process (service/Operation/Process) is utilizing what number of CPU and memory.
** I can get the CPU and Memory utilization per Cache.exe and PID, but not able to get the Namespace and ConfiguratioName to which that particular PID belongs.
Thank you,
It's been a while since I've posted about Embedded Git on the Developer Community, and I'd like to provide an update on the massive amount of work we've done this year and where we're going next.
If you're building solutions on IRIS and want to use Git, that's great! Just use VSCode with a local git repo and push your changes out to the server - it's that easy.
But what if:
In your Interoperability Production you could always have a Business Operation that is an HTTP client, that uses OAuth 2.0 for authentication, but you had to customize the Operation for this authentication methodology. Since v2024.3, which was lately released, there is a new capability, providing new settings, to handle this more easily.
Imagine the scene. You are working happily at Widgets Direct, the internet's premier retailer of Widgets and Widget Accessories. Your boss has some devastating news, some customers might not be fully happy with their widgets, and we need a helpdesk application to track these complaints. To makes things interesting, he wants this with a very small code footprint and challenges you to deliver an application in less than 150 lines of code using InterSystems IRIS. Is this even possible?
Hi Community,
We're excited to invite you to the webinar 2025 Data Management: Technology Trends & Predictions.
Join this webinar for an engaging and insightful tech talk on the latest trends in data management technology in the UK and Ireland.
⏱ Date & Time: Thursday, January 23, 10:30 AM GMT
👨🏫 Speakers:
When developing a new Interoperability Production, it is quite natural that settings are initially added in the Production.
However, as soon as you want to move the Production from development to a test or staging environment, it becomes clear that some settings like HTTP Servers, IP addresses and/or ports need to be changed. In order to avoid these settings being overwritten during a redeployment later on, it is essential that you move these settings from the Production to the System Default settings.
Last Chapter: Creating a REST client to get Tracks from Spotify REST API - Part3 Get some data (e.g. Artists)
Git link: https://github.com/ecelg/InterSystems-IRIS-as-a-Spotify-REST-client
OK we create a method to get data and lets try to get some Tracks 😁
Run the following line
w ##class(rest.utli.requestUtli).getdata("Spotify","/search","offset=5&limit=10&query=Shape%20of%20you&type=track&market=SG")ooooo no seems there is huge among of data returns.....😥
I would like to know what information can be found in 1 track....🤔 how about only query 1 track?
Last Chapter: Creating a REST client to get Tracks from Spotify REST API - Part1 Check out token
Git link: https://github.com/ecelg/InterSystems-IRIS-as-a-Spotify-REST-client
Ok... Now we can check out a token but it will be expired in 3600 seconds.
There are 2 questions come up🤔
1. How to save this token????🙄
2. How to refresh this token????🤨🤔
Lets come back to the API document https://developer.spotify.com/documentation/web-api/tutorials/getting-started
Base on my understanding, this piece of API do not have a token called refresh_token, as a result, we can assume the logic like following
This sample was cloned from iris-interoperability-template. I have reconfigured the interoperability Production with an Inbound HTTP Adapter which is used by a HTTP Business Service. The configuration details for the business service are specified in System Default Settings.
I configured Call Interval setting to call HTTPServer once every hour. You can change both the URL and frequency in the service's settings.
Hi Community,
In this article, I will introduce my application iris-HL7v2Gen .
We are building a data transformation from HL7 to custom XML. We've got an XML schema, and are using virtual documents (EnsLib.EDI.XML.Document).
We can:
The ability to resend messages easily has always been a strong feature of our Interoperability capabilities.
With v2024.3 coming out soon (available already now as Developer Preview) out already we've made this even easier!
This demo has an interoperability production with 16 items. 
The first part of this demonstration consists of sending an HL7 SIU file which will be transmitted to the 2 other HL7 flows (HTTP and TCP), and transformed and transmitted to the Kafka server. HTTP and TCP flows will transform HL7 messages in the same way before sending them to Kafka as well.
When building a bundle from legacy data, I (and others) wanted to be able to control whether or not the resources were generated with a FHIR Request Method of PUT instead of the hard coded POST. I have extended the two classes responsible for transforming SDA to FHIR in an Interoperability Production to accomodate a setting that lets the user control the Request Method.
Is there a way to create and establish DICOM Association with Extended Negotiation?
I have implemented DICOM Query/Retrieve C-FIND, using EnsLib.DICOM.Operation.TCP and EnsLib.DICOM.Process base classes. My application, acting as an SCU, needs to query by Study Date-Time (combined date-time matching) range with timezone query adjustment. For this, I need to use Extended Negotiation.
I've checked the IRIS Manual - Creating DICOM Associations section but there is no mention of this.
Hello,
Please, we would need your help 🙂:
In a development environment, we have added quite a few presentation contexts to the DICOM configurations (the associations). We would need to find a way to export them from this environment to make it easier for us to import them in PRO (and avoid doing it by hand one by one).
Hi Community, OpenAPI-Client Gen has just released, this is an application to create an IRIS Interoperability Production client from Swagger 2.0 specification. Instead of the existing tool ^%REST that creates a server-side REST application, OpenAPI-Client Gen creates a complete REST Interoperability Production client template.
Install by ZPM:
zpm "install openapi-client-gen"
How to generate production from Swagger document? It's very simple.
Open a terminal and execute:
Set sc = ##class(dc.openapi.client.Spec).generateApp(<applicationName>, <Your Swagger 2.0 document>>)
This is a template for a FastApi application that can be deployed in IRIS as an native Web Application.
git clone
cd iris-fastapi-template
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
docker-compose up
The base URL is http://localhost:53795/fastapi/.
I was working on a DTL but kept getting ERROR #5002... MAXSTRING errors. The problem was that most of the DTL GUI action steps only support the string data type when working with the segments. A %String has a limit of 3,641,144 characters and my OBX5.1 was 5,242,952 characters long as the example provided. Of course PACS admin stated ultra high quality up to and including 4K resolution files were needed, so we could not get the vendor to compress or reformat these files to compressed jpg or something similar.
In the past, I've created custom SQL operations, but now I had something trivial to do, so I decided to take EnsLib.SQL.Operation.GenericOperation out for a spin. There's no example in the docs, so it was a little tricky. Here's what I ended up doing:
In my external database, I have 'mytable' with two fields 'id1' and 'id2'. Here are the pertinent Business Operation settings:
SQL: select id2 from mytable where id1 = ?
Input Parameters: [1] *id1
RequestClass: Ens.StringRequest
ResponseClass: MyResponseClass
