Motivation

I didn't know about ObjectScript until I started my new job. Objectscript isn't actually a young programming language. Compared to C++, Java and Python, the community isn't as active, but we're keen to make this place more vibrant, aren't we?

I've noticed that some of my colleagues are finding it tricky to get their heads around the class relationships in these huge projects. There aren't any easy-to-use modern class diagram tool for ObjectScript.

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.

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.

Only method/routine executed as "do Method..." is included into $ESTACK.
How can I modify a method or routine that returns a value so it can be included in $ESTACK?
Example upon executing via Studio Debug ($ESTACK is converted to string with ">" delimiter):
Expected: stackstr = %Debugger.System.DebugStub > LogGenerate > Entry > DirChain > Attributes > LogNew > LogSize > LogFormat > LogWrite
Processes DirChain, LogNew, LogSize, LogFormat are executed as "If Method..."

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

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:

HTTP and HTTPS with REST API

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:

Hi,

I'd like to report a really strange behavior of the Intersystems Lite Terminal after executing a simple ObjectScript instruction.

From the Intersystems Lite terminal, execute the following instructions:

- Set uniqueId = "12345678_1"
- Set uniqueId = $p(uniqueId,"_",1)_"_"_($p(uniqueId,"_",*)+1)
After executing the second instruction, the terminal closes without any error.

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.

Hello everyone! 👋

I have a question regarding roles and resources.

To give you some context: I have a user who has been assigned only the role %HS_UsageDashboard_Access.This allows them to access the dashboards correctly (by giving the direct URL). Then, if I try to access the Management Portal with this same user, I can log in with no access to any resources within it (as expected).
