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.

InterSystems IRIS Adaptive Analytics version 2025.4.1 is now available from the InterSystems Software Distribution page.  This release includes AtScale 2025.4.1 and is compatible with the existing  Adaptive Analytics User-Defined Aggregate Function (UDAF) file - 2024.1.  New features included in AtSCale's 2025 releases include:

• Several MDX improvements to better handle null values and semi-additive measures like year-to-date.
• New parameters to enable setting the visibility of calculations and calculation groups in BI tools.

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.

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.

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.

⏯ Analytics and AI with InterSystems IRIS - From Zero to Hero @ Ready 2025

For example, I'm creating a customer at front end interface. I want to list down all the routines and child sub routines that are called at backend in mumps/cache. What's the best way to do it?

Yes, that's right, a Cache 2017.1 question.  Let's all take a trip in the Wayback Machine.

The company I'm working for is in the process of starting to use the %UnitTest framework, and we are experiencing some errors in the code with some existing logic.  Long story short, it looks like the best way to handle the issue would be to recognize we're executing the job as a part of a unit test.  Is there any sort of variable or property that can be checked to confirm the process is indeed executing a unit test?

Hi All,

First I want give a Shout Out to @Theo Stolker  and @Rupert.Young. Because they helped me with the solution.

 When you're using the EnsLib.SQL.Snapshot as a Property in the Response Message to return Snapshot data (,e.g.: from Business Operation to Business Process,) the Snapshot data won't be cleaned with the Purge messages task/service.

Class ResponseMessage Extends Ens.Response

{

    Property SnapshotProp As EnsLib.SQL.Snapshot;

}

The data will be stuck in the global: ^Ens.AppData. You can find it with this query in System>Globals:  ^Ens.AppData("EnsLib.SQL.

      ⏯  Source Control Interoperability Productions in a Decomposed Format @ Ready 2025

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 repeated logs?

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.

Environment:
    Targeted *.inc file (with hundreds of defined macros) is in use throughout the application and included into every class declaration.
    Statement "set a = $$$TestIf(3)" is included into a classmethod with no other code in. Expected output 5
Same macro options in *.inc:
    #define TestIf(%arr)    if %arr>0 QUIT 5
    #define TestIf(%arr)    if (%arr>0) {QUIT 5}
Issue:
    failure to compile class with the same error on all tried definition options as:

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.

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.
