Exposing a Basic REST API with InterSystems IRIS: Step-by-Step Docker Example

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

  • A persistent data class
  • A REST class with GET and POST methods
  • A web application to expose the API
  • A full demonstration using Docker

Step 1: Create the data class Demo.Producto

Class Demo.Producto Extends (%Persistent, %JSON.Adaptor) {
  Property Nombre As %String;
  Property Prec

What is the most efficient way to debug encoding characters issues?

Hello, how are you?

Using Healthshare for Interoperability, we often see a wide variety of encoding issues. Some happen when transforming XML to HL7. Some happen the other ay around transforming HL7 to XML.

Is there a valid way to understand which encoding needs to be used?

I ask, because we use SOAP or REST or TCP HL7 services.

And we deliver messages with TCP HL7, SOAP, HTTP Operations.

And we often face this issue where special characters like ñ or á, are not encoded correctly.

Thanks for your replies.

Expose %Stream property in JDBC as CLOB

I need to reproduce a table (in fact a view, but let's start with a simple table 😊) in IRIS as the currently used in Oracle.

I need to expose/project one column to JDBC as CLOB, in my class I have the corresponding property defined as:

Property GlobStream As %Stream.GlobalCharacter;

In JDBC this column is projected as LONGVARCHAR, this is compliant with the documentation but I need to project it as CLOB.

In addition, I'm no expert in JDBC but wit seems that LONGVARCHAR has a Maximum Length 32,700 characters in JDBC, not quite enough for an arbitrary stream.

Is it possible to project a %St

Facial Recognition with InterSystems Vector Search and DeepFace

The facial recognition has become the most popular method for validating people's identities, thus enabling access to systems, confirmation of personal and documentary data, and approval of actions and documents.
The challenges are related to performance when the database is very large, accuracy, and especially the privacy of biometric facial data. For these challenges, nothing is better than using InterSystems Vector Search, as it allows:

  1. Performing vector searches in millions of records with much faster responses than traditional methods.
  2. The vector and mathematical models used by Vector Search

How to best cascade deletes for a property that is a list of a persistent class?

I have a persistent class (GetOrgUpdatesResponse) that has a property which is a list of another persistent class (Organization).

What would be the best way to cascade deletes so that on deletion of a parent row each object in the list property is then also deleted? 

I have included a sample of my classes here for clarity

M-U5K-3T: When Code Golf Meets Planetary Survival

cover

Picture a dark room. The only light comes from a wall of displays and a blinking prompt that politely informs you:

“LINK TO M-U5K-3T: HIGH LATENCY – DIRECT CONTROL DISABLED.”

Perfect.

You are supposed to be a Rover Commander in the Musketeer Corps. Somewhere absurdly far away, you have an autonomous unit parked on a hostile exoplanet. It wants you dead, but it’s also covered in minerals that could fund a small civilization.

The ore on M-U5K-3T is everywhere. Unfortunately, everything else on the surface is actively trying to kill you.

So, we don't pilot. We script.

Beyond IntegratedML: What are our options for Continuous Training (CT) in IRIS?

Hello everyone,
I’m looking to implement Continuous Training (CT) as part of an MLOps strategy for some data science projects in IRIS. I want to automate the full cycle:


- Monitoring model performance & accuracy degradation.
- Retraining models automatically.
- Validating and updating production models.


I’ve looked into IntegratedML, but it seems more focused on the SQL interface for training (AutoML). Even with the new Custom Models (beta), which allows for more flexibility with Python, it doesn't seem to provide the "Continuous" orchestration out of the box.


I’d like to know:

Ensemble ASTM Service: "Expected <ENQ>; got: <ETX>" and TCP Connection Stuck in "Connecting" via Moxa NPort 5110

Hi everyone,

I am currently integrating a Sysmex analyzer with InterSystems Ensemble/IRIS using a Moxa NPort 5110. I have successfully verified the physical and serial layers, but I am facing two specific issues: a protocol sync error and a persistent TCP connection state.
Environment:
Interface: ASTM.

Gateway: Moxa NPort 5110 (TCP Client Mode).

Server: Ensemble Business Service (EnsLib.ASTM.Service.TCPService).

Port: xxxx.

Current Status & Observations:
Serial Layer: Verified. The Moxa "Async Monitor" shows RxCnt increasing when the instrument sends data. Hardware pins (DSR/CTS) are ON.

Building the UI by Prompting vs InterSystems IRIS Backend: Lovable, Spec First and REST API

Hi developers!

Observing the avalanche of AI-driven and vibe-coding developer tools that have been appearing lately almost every month with more and more exciting dev features, I was puzzled whether it is possible to leverage it with InterSystems IRIS. At least to build a frontend. And the answer - yes! At least with the approach I followed.

Here is my recipe to prompt the UI vs InterSystems IRIS Backend:

  1. Have the REST API on the IRIS side, which reflects some Open API (swagger) spec.
  2. Generate the UI with any vibe-coding tool (e.g., Lovable) and point the UI to the REST API endpoint.
  3. Profit!

Here is the result of my own exercise - a 100% prompted UI vs IRIS REST API that allows to list, create, update delete entries of a persistent class (Open Exchange,frontend source, video):

What is the recipe in detail?

FastHTTP : Simplify Your HTTP Requests in ObjectScript

Introduction

The standard %Net.HttpRequest library in InterSystems IRIS is powerful and comprehensive, but it can be verbose for simple operations. Writing an HTTP request often requires several lines of code to instantiate the class, configure the server, the port, HTTPS, add headers, and finally send the request.

When testing in the terminal, this configuration quickly becomes too heavy, and usually ends up with the creation of temporary methods...

FastHTTP was designed to address this need. This utility class provides a fluent and concise interface to perform HTTP calls in a single line, while automatically handling the underlying complexity (SSL/TLS, URL parsing, JSON encoding, headers, etc.).

How to Find Applications Installable With Package Manager

Hi Community!

@Joan Pérez published a review that it is not very clear what applications are available for InterSystems Package Manager. Thanks Joan! Indeed it deserves a post.

There at least two ways I know to showcase them:

1. Run find command in zpm:

IRISAPP>zpm

=============================================================================
|| Welcome to the Package Manager Shell (ZPM).                             ||

Vector Search with Embedded Python in InterSystems IRIS

One objective of vectorization is to render unstructured text more machine-usable. Vector embeddings accomplish this by encoding the semantics of text as high-dimensional numeric vectors, which can be employed by advanced search algorithms (normally an approximate nearest neighbor algorithm like Hierarchical Navigable Small World). This not only improves our ability to interact with unstructured text programmatically but makes it searchable by context and by meaning beyond what is captured literally by keyword.

In this article I will walk through a simple vector search implementation that Kwabena Ayim-Aboagye and I fleshed out using embedded python in InterSystems IRIS for Health. I'll also dive a bit into how to use embedded python and dynamic SQL generally, and how to take advantage of vector search features offered natively through IRIS.

"IRIS-CoPilot" prototype - English (etc) as an IRIS language?

Keywords:  IRIS, Agents, Agentic AI, Smart Apps

Motive?

Transformer based LLMs appear to be a pretty good "universal logical–symbolic abstractor".  They started to bridge up the previous abyss among human languages and machine languages, which in essence are all logic symbols that could be mapped into the same vector space. 

Objective?

Wondering for 3 years we might be able to just use English (etc human natural languages) to do IRIS implementations as well, one day. 

Possibly tomorrow all machines, software and apps will be "intelligent" enough to interact with users in any human languages to get
