REST API (Representational State Transfer Application Programming Interface) is a standardized way for web applications to communicate with each other using HTTP methods like GET, POST, PUT, DELETE, etc. It's designed around resources, which can be anything from a user to a file. Each resource is identified by a unique URL, and interactions with these resources are stateless, meaning each request from a client to a server must contain all the information needed to understand and process the request. This statelessness, along with the use of standard HTTP methods, makes REST APIs highly scalabl

Dear community, I have a confession to make. I have not gotten over Zen yet. Alas, all good things must come to an EOF, so I am currently learning about Angular. I am working on proving to myself that with the right back end and Angular components, I can deliver to myself and my team a very Zen-like experience in this environment. Since this is my first attempt, here is a fair warning: I will be providing some rather large code samples before discussing them. Please warm up your mouse and hand for extensive upcoming scrolling! Also, a note on the code snippets: many of them are labeled "Javasc

Question Yone Moreno Jiménez · Feb 28, 2025

Good morning,

We need your help:

We wonder if there is a way to filter EnsLib.DICOM.Document, by using its DataSet properties on the Message Viewer.

For example, we would like to find the following DICOM.Document which DataSet.AccessionNumber is SR115985013100

By using the Message Viewer Filter we have tried the following:

FixedDataSet.AccessionNumber = SR115985013100

Because when we look fod a Body Property of the EnsLib.DICOM.Document it shows this drop down menu:

However, it replies with an error:

ERROR #5540: SQLCODE: Message -29: Field 'ENSLIB_DICOM.DOC

Question Scott Roth · Jul 3, 2025

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

  • How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
  • Do I have to then do another "fromDao" to pull the list into string format?
  • How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

For my intern project, I am building a Flask REST API backend. My goal is to host it on InterSystems IRIS using the WSGI interface. This is a relatively new approach and is currently only being used in a handful of projects such as AskMe. To help others get started, I decided to write this article to simplify the process.

Creating a Basic Flask App

First, let’s create a minimal Flask application. Here is the code:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

@app.route('/test')deftest():return"Test"if __name__ == "__main__":

Hi Developers!

There is a free ObjectScriptQuality tool for ObjectScript developers who upload solutions on GitHub. This tool helps developers validate ObjectScript code using a variety of rules, based on common code errors.

There are currently 16 rules in this tool, but there are definitely many more rules to consider when testing ObjectScript code.

Could you suggest any other rules to add to this tool?

Note: You can submit it as an idea on the InterSystems Ideas for the 2nd Idea-A-Thon contest. Source control tools help developers reduce the time to test, develop and deploy applications,

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class. Then also there is a screenshot of my web application I made specifically

☤ Care 🩺 Compass 🧭 - Proof-of-Concept - Demo Games Contest Entry

Introducing Care Compass: AI-Powered Case Prioritization for Human Services

In today’s healthcare and social services landscape, caseworkers face overwhelming challenges. High caseloads, fragmented systems, and disconnected data often lead to missed opportunities to intervene early and effectively. This results in worker burnout and preventable emergency room visits, which are both costly and avoidable.

Care Compass was created to change that.

Hello,

I'm trying to connect a Python backend application to an InterSystems IRIS Community Edition instance running in a Docker container on an AWS EC2 instance. I'm facing persistent connection issues and an SSL Error despite the Superserver apparently having SSL disabled. I'm hoping for some insight into what might be causing this contradictory behavior.

My Setup:

InterSystems IRIS 2024 recently introduced the vector types. This addition empowers developers to work with vector search, enabling efficient similarity searches, clustering, and a range of other applications. In this article, we will delve into the intricacies of vector types, explore their applications, and provide practical examples to guide your implementation.

At its essence, a vector type is a structured collection of numerical values arranged in a predefined order. These values serve to represent different attributes, features, or characteristics of an object.

Question Ward De Backer · Oct 26, 2022

Hi,

If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally  all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:

  • myFunction(params, callbackFunction(response))
  • myFunction(params).then(resolveFunction(response))
  • async someFunction() {
    ​​​​​  response = await myFunction(params)
    }

Question Anna Golitsyna · Jul 9, 2025

I like Application Error Log a lot, both for its full stack and a big list of variables. I'd like to "hack" this functionality and record the same in this log when a certain variable has a certain value. This quasi error should not be visible to the user, and it should not interrupt the application flow. Is that possible?

Throwing an error in a try-catch block does not record the error, tested. I am considering recording variables and the stack differently, I know how to do both, but that would miss the nice Application Error Log functionality.
