What is XML?

XML(eXtensible Markup Language) is a flexible, text-based, andplatform-independentformat used to store and transport data in a well-structured way that is both human- and machine-readable. XML permits users to define custom tags to describe the meaning and organization of their data. For example: <book><title>The Hitchhiker's Guide</title></book>.

An XML document is self-descriptive and structured as a hierarchical tree of elements. Every document has a single root element that encapsulates all other content.

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.

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.

InterSystems ObjectScript extension for VS Code, version 3.0.1

Am also asking this question on the extension's GitHub page: Request textDocument/documentSymbol failed. Error: name must not be falsy · intersystems-community/vscode-objectscript · Discussion #1530 - but suspect more eyes will see it here, which might help gather additional information.

Tried to compile some legacy ObjectScript code via Import/Compile in VS Code using the vscode-objectscript extension. Getting an error, and the content of the file is left changed on the filesystem simply by being compiled.

We are trying to mark a hl7 nack as "completed" to ignore an error and not generate the alert. 

We can remove from adding a managed alert or add another router in 

When Nack of CR of 

Date of birth in PID.7 must not be empty

We tried via this but i think it's only for an actual IRIS alert errror not the HL7 error code/description 

E*Date of birth in PID.7 must not be empty=C,:?CR=C,:?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C

Real Time FHIR® to OMOP Transformation

This part of the OMOP Journey,  we reflect before attempting to challenge Scylla on how fortunate we are that InterSystems OMOP transform is built on the Bulk FHIR Export as the source payload.  This opens up hands off interoperability with the InterSystems OMOP transform across several FHIR® vendors, this time with the Google Cloud Healthcare API.

I am regularly contacted by customers about memory sizing when they get alerts that free memory is below a threshold, or they observe that free memory has dropped suddenly. Is there a problem? Will their application stop working because it has run out of memory for running system and application processes? Nearly always, the answer is no, there is nothing to worry about. But that simple answer is usually not enough. What's going on?

Consider the chart below. It is showing the output of the free metric in vmstat.

Hello community,

I wanted to share my experience about working on Large Data projects. Over the years, I have had the opportunity to handle massive patient data, payor data and transactional logs while working in an hospital industry. I have had the chance to build huge reports which had to be written using advanced logics fetching data across multiple tables whose indexing was not helping me write efficient code.

Here is what I have learned about managing large data efficiently.

Choosing the right data access method.

As we all here in the community are aware of, IRIS provides multiple ways to access data. Choosing the right method, depends on the requirement.

• Direct Global Access: Fastest for bulk read/write operations. For example, if i have to traverse through indexes and fetch patient data, I can loop through the globals to process millions of records. This will save a lot of time.

Set ToDate=+HSet FromDate=+$H-1ForSet FromDate=$O(^PatientD("Date",FromDate)) Quit:FromDate>ToDate  Do
. Set PatId=""ForSet PatId=$Order(^PatientD("Date",FromDate,PatID)) Quit:PatId=""Do
. . Write$Get(^PatientD("Date",FromDate,PatID)),!

• Using SQL: Useful for reporting or analytical requirements, though slower for huge data sets.

Hello InterSystems Community,

I hope you're all doing well. I'm reaching out to ask if there's any way to enable a dark theme or dark mode for the HealthShare Management Portal.

Background

I have a visual impairment (amblyopia/lazy eye) which means I'm nearly blind in one eye. Like many people with visual difficulties, I find that bright white backgrounds and interfaces cause significant eye strain and fatigue. This makes it challenging to work with the Management Portal for extended periods.

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)

NAMING THINGS RANDOMLY

We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare. 

➡ Pick clear, consistent names from the start. Think of it as leaving breadcrumbs for your future self and your teammates.

Hi Team, 

Can I please check if anyone has built a simple web interface for maintaining custom SQL lookup class.   

We have a simple persistent class in HealthShare which is used for storing Pathology test codes. Test codes in this lookup class is used for message filtering and applying additional logic when processing pathology results/orders. 

We want to make this class available to external users from pathology (not the usual management portal users) to maintain so that they can add/edit/delete test codes as required.

Overview

This web interface is designed to facilitate the management of Data Lookup Tables via a user-friendly web page. It is particularly useful when your lookup table values are large, dynamic, and frequently changing. By granting end-users controlled access to this web interface (read, write, and delete permissions limited to this page), they can efficiently manage lookup table data according to their needs.

The data managed through this interface can be seamlessly utilized in HealthConnect rules or data transformations, eliminating the need for constant manual monitoring and management of the lookup tables and thereby saving significant time.

Note:
If the standard Data Lookup Table does not meet your mapping requirements, you can create a custom table and adapt this web interface along with its supporting class with minimal modifications. Sample class code is available upon request.

I have a custom defined priority field that is being stored as a number type

<record name="LocalClinicalMeSHTerms" type="serial">
<field name="LocalClinicalExpertiseCodedValue" type="{CODETYPE}" codeFamily="HSPD" codeTable="LocalClinicalExpertise" codeScheme="{MASTER}"/>
<field name="LocalCliniclDisplayOrder" type="number"/>
</record>

However, within the overviewIndividual.cls form

				{
					"type": "HSPD.collection",
					"key": "LocalClinicalMeSHTerms",
					"hideExpression": "formState.lib.hideField(formState) && model.

Deploying new IRIS instances can be a time-consuming task, especially when setting up multiple environments with mirrored configurations.

I’ve encountered this issue many times and want to share my experience and recommendations for using Ansible to streamline the IRIS installation process. My approach also includes handling additional tasks typically performed before and after installing IRIS.

This guide assumes you have a basic understanding of how Ansible works, so I won’t go into much detail on its fundamentals.

UPDATE: since version 0.0.4 of the extension was published on 2025-11-23 it is now possible to use gj :: configExplorer directly in VS Code on Windows.

In my previous article introducing gj :: configExplorer I flagged up how an apparent bug in the Windows elements of the Native API for Node.js means it's not currently available to run in VS Code on a Windows desktop. In a comment on that article I offered a workaround, but this requires a Docker-equipped Linux host you can SSH to.

If you don't have a suitable target it's now possible to leverage your local Windows Docker Desktop.

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

If you are looking for high availability you could use:

a) Kong Traditional Mode: Multiple Node Clusters

b) Hybrid Mode

c) DB-less Mode

Before we break them down let's first understand the out of the box deployment that is provided by InterSystems: Installing IAM Version 3.10.

At the moment, we have 10 HealthShare instance servers (5 x mirrored pairs), where we implement an External Backup approach, using the freeze/thaw commands against whichever server of the pair is the backup mirror member, to complete a VM level backup. These backups are stored to a disk within our control, to purge as required. This approach allows us to deliver a zero downtime backup approach.

Hi,

%SYS.LDAP - InterSystems IRIS Data Platform 2025.2 - including private class members   states that
 

"abstract class %SYS.LDAP

Requires %syLDAP.INC to be included in your COS routine for some macro definitions."

How can I include %syLDAP.INC for the compilation of my code which uses %SYS.LDAP ?   I need the definitions for the $$$LADPxxxx macros (such as $$$LDAPSUCCESS).

Thank you.

Hi, Community!

Need to install a HealthShare solution module? Follow this simple step-by-step process to get started!

Deploying HealthShare Solution Modules with InterSystems Package Manager

I’ve been exploring options for connecting Google Cloud Pub/Sub with InterSystems IRIS/HealthShare, but I noticed that IRIS doesn’t seem to ship with any native inbound/outbound adapters for Pub/Sub. Out of the box, IRIS offers adapters for technologies like Kafka, HTTP, FTP, and JDBC, which are great for many use cases, but Pub/Sub appears to be missing from the list.

Has anyone here implemented such an integration successfully?

For example:

• Would it make sense to leverage IRIS’s Business Service + REST API adapter to connect to Google’s Pub/Sub REST endpoints?

I want to integrate Google Cloud Pub/Sub with InterSystems IRIS(HealthShare) and I see that InterSystems does not provide any out of the box Inbound/Outbound adapters for this integration though it has adapters for Kafka and other similar services. Any suggestions would be really appreciated.

I joined InterSystems less than a year ago. Diving into ObjectScript and IRIS was exciting, but also full of small surprises that tripped me up at the beginning. In this article I collect the most common mistakes I, and many new colleagues, make, explain why they happen, and show concrete examples and practical fixes. My goal is to help other new developers save time and avoid the same bumps in the road.

1. Getting lost among system classes and where to start

The issue: ObjectScript/IRIS ships with many system classes and packages (%Library, %SYS, %Persistent, %SQL, etc.).

Introduction

HL7 messages often contain multiple repeating segments such as NTE, AL1, OBX, ZTX, DG1, and others. These segments sometimes require individual processing and routing to different downstream systems. This technical paper introduces a configurable template designed to automate the splitting of these repeating HL7 segments, improving message handling and integration efficiency.

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()).

1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

Our vendor is developing an interface API on their end to capture HL7 data on a Server Port, and they require us to send a pre-defined HL7 Order message for testing every hour until the API is completely operational.

Is it possible to accomplish that in a Business Operation automatically without utilizing a service or process? The BO is a standard TCP/IP connection.

I'm manually sending the message again from the Operations right now. I do not have access to the System Operation to use the Task Manager feature.
