When we create a FHIR repository in IRIS, we have an endpoint to access information, create new resources, etc. But there are some resources in FHIR that probably we wont have in our repository, for example, Binary resource (this resource returns a document, like PDF for example).

I have created an example that when a Binary resource is requested, FHIR endpoint returns a response, like it exists in the repository. 

First of all, we need a Namespace and a FHIR endpoint. After this, we need to configure an Interoperability production that will be connected to the FHIR endpoint. This production

Introduction

My guess is that most IRIS developers create their applications using its native ObjectScript language or, if using an external language, then most likely using either Java, Python or perhaps C++.

I suspect that only a minority have considered using JavaScript as their language of choice, which, if true, is a great shame, because, In my opinion and experience, JavaScript is the closest equivalent to ObjectScript in terms of its ability to integrate with the IRIS's underlying multi-dimensional database. 

In this article I'd like to lay out the case for JavaScript as a first-clas

Hello
This article follows up on the question I had asked the community UDP Adapter not working
In this article, I will present to you
1) What is "UDP"?
2) The current state of Iris with UDP
3) My solution with the UDP adapter

1) What is "UDP"?

UDP stands for User Datagram Protocol. It is one of the core protocols of the Internet Protocol (IP) suite, used for transmitting data over a network. Here are some key features of UDP:

1. Connectionless: UDP does not establish a connection before sending data, which means it can send messages (datagrams) without prior handshaking.
2. Unreliable: There is no

Mirror Your Database Across the Galaxy with Seeding

Hello cpf fans!  This distraction I used the "seed" capability in IRIS to provision an entire IrisCluster mirror, 4 maps wide with compute starting from an IRIS.DAT in a galaxy far far away.  This is pretty powerful if you have had a great deal of success with a solution running on a monolithic implementation and want it to scale to the outer rim with Kubernetes and the InterSystems Kubernetes Operator.  Even though my midichlorian count is admittely low, I have seen some hardcore CACHE hackers shovel around DATS, compact and shrink and update their ZROUTINES, so this same approach could also be helpful shrinking and securing your containerized workload too.  If you squint and feel all living things around you,  you can see a glimpse of in place (logical) mirroring in the future as a function of the operator and a migration path to a fully operational mirrored Death Star as the workload matures.

High-Performance Message Searching in Health Connect

The Problem

Have you ever tried to do a search in Message Viewer on a busy interface and had the query time out? This can become quite a problem as the amount of data increases. For context, the instance of Health Connect I am working with does roughly 155 million Message Headers per day with 21 day message retention. To try and help with search performance, we extended the built-in SearchTable with commonly used fields in hopes that indexing these fields would result in faster query times. Despite this, we still couldn't get some of these queries to finish at all.

Introducing IRIS DocDB Explorer: A Sleek UI for Managing JSON Documents in InterSystems IRIS

IRIS offers a dedicated feature for storing and retrieving JSON documents using DocDB, without requiring a predefined schema.

Developers often need a quick and intuitive way  to browse, create, and edit documents without switching between multiple tools or writing repetitive code. To solve this, I creatediris-docdb-ui — a CSP-based open-source application that provides a clean, responsive interface for interacting with DocDB effortlessly. Users can easily create namespaces and document databases, vi

Over time, while I was working with Interoperability on the IRIS Data Platform, I developed rules for organizing a project code into packages and classes. That is what is called a Naming Convention, usually. In this topic, I want to organize and share these rules. I hope it can be helpful for somebody.

Disclaimer: This guide is a good fit for Interoperability projects. When you have integrations, data flows, when you use IRIS for ETL processes, etc. Overall, when your code is combined with Productions. If you are using the IRIS Data Platform just as a backend, for example, the project str

Hi everyone,

I'm dealing with a situation where LOAD DATA operations — especially large batches with data inconsistencies — are consuming a lot of disk space. I've noticed that the same error messages are being repeatedly logged in the %SQL_Diag.Result and %SQL_Diag.Message tables, which is significantly increasing the size of the database.

One idea was to move these diagnostic tables to a separate database with a configured size limit, but before going down that path, I'd like to ask:

Is there a simpler or more efficient way to handle this?
For example:

• Can we limit the number of repeate

Hello,
I am currently facing the task of retrieving or sending HL7 messages from a web API. Since we only send HL7 messages via internal sockets, web APIs are relatively new to me.
The following is my plan for the new interface:
I have created a new custom business service that periodically sends requests to a business process. In this business process, the HTTP request (HTTP.GenericMessage) is then created from scratch. The special feature is the "Authorisation" header field, where a signature is inserted, which consists of a base64-encoded hash value. The request is then sent to the API via a b

Same macro options in *.inc:
    #define TestIf(%arr)    if %arr>0 QUIT 5

HTTP and HTTPS with REST API

Hello

The HTTP protocol allows you to obtain resources, such as HTML documents. It is the basis of any data exchange on the Web and a client-server protocol, meaning that requests are initiated by the recipient, usually a Web browser.

REST APIs take advantage of this protocol to exchange messages between client and server. This makes REST APIs fast, lightweight, and flexible. REST APIs use the HTTP verbs GET, POST, PUT, DELETE, and others to indicate the actions they want to perform.

When we make a call to a RESt API, what actually happens is an HTTP call. The API receives this call and according to the requested verb and path, the API performs the desired action. In the case of the Iris implementation we can see this clearly in the URLMap definition area:

Introduction

In InterSystems IRIS 2024.3 and subsequent IRIS versions, the AutoML component is now delivered as a separate Python package that is installed after installation. Unfortunately, some recent versions of Python packages that AutoML relies on have introduced incompatibilities, and can cause failures when training models (TRAIN MODEL statement). If you see an error mentioning "TypeError" and the keyword argument "fit_params" or "sklearn_tags", read on for a quick fix.

Root Cause

• scikit-learn updated to version 1.6.0, deprecating fit_params.
• scikeras is no longer updating the "
