Sometimes it is more convenient, more efficient, and more secure, to limit FHIR Searches per pre-defined "Lists" of Resources.

Since v2025.1 we support several List-related features in our FHIR Server.

I will highlight these here, and provide some samples.

I have see this discussed on the community but I'm not quite finding an answer. 

I have a Photo that is stored as an VARBINARY within MS SQL. I would like to Select the data into a EnsLib.SQL.Snapshot, is that possible? I would take it out of the Snapshot and send it to a %Stream so it can be written out to a file.

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.

Hey Community,

Hi Developers!

Sometimes we need to deal with classes/tables where the primary key and the IdKey are something that is maintained by yourself.

What is the proper way to generate a new ID in case where ID is a %BigInt?

Property id As %Library.BigInt

Are there any system methods to provide it?

There is data already imported via SQL, so there is no last ID stored in ^myclassD, so I cannot do $I(^myclassD).

Thinking of:

set newid=$O(^myclassD(""),-1),newid=$I(newid)

What do you think?

Hello community!
I have a small challenge for you :)

One of customers is sending quite a lot of messages between interoperability components, which mix standard request content and streams representing serialized JSON objects. As these JSON streams can be quite long (but not too long, just couple hundreds of characters) they would appreciate if the JSON content of stream was displayed in a nice-to-read way, using syntax highlighting by message trace view.

Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

• First Step: Reverse Cipher

  • Reverse the entire input string.
  • Relocate the last character of the original string (now the first character of the reversed string) to the end.

• Second Step: Alphabetic Index Binary Encoding

  • For each alphabetic character, determine its zero-based index in the lowercase alphabet (a-z).
  • Replace odd-indexed characters with '1' and even-indexed characters with '0'.
  • Preserve non-alphabetic characters unchanged.

Example:

using  intersystemsdc/iris-ml-community:latest I failed with

Error: Invalid Community Edition license, may have exceeded core limit.
Shutting down the system : $zu(56,2)= 0Starting IRIS

What is the actual valid version with ML ??

Hi everyone,

I am currently setting up InterSystems API Manager (IAM) 3.4.3.11 using Docker. The installation is successful, the license is active, and I can access the Manager (port 8002).

I am now trying to secure the Administration Portal using basic-auth. I've found some documentation stating that I should:

1. Go to the Teams section in the UI.
2. Click on Invite Admin to create the first user.
3. Only then, enable KONG_ENFORCE_RBAC and KONG_ADMIN_GUI_AUTH in the docker-compose.yml.

We are implementing delegated auth between Kong Gateway and IRIS. Kong is correctly configured to forward JWT authenticated requests with consumer headers (X-Consumer-Username, etc.) to IRIS, but the ZAUTHENTICATE routine (deployed in the %SYS namespace) never executes, leaving ZW ^ZAUTHLOG empty despite successful header delivery.

Defining my first REST API within InterSystems using iris-rest-Api-template as a basis and I am seeing if someone could provide me some guidance to see if I can make it work.  

In some of my other posts, I have been trying to come up with a way for our Enterprise Application Development team which works with .Net to build Applications to make a REST call to our instance of InterSystems to query some of the Cache Tables we have defined. 

Using the iris-rest-api-template, I have created the osuwmc.DataLookup.REST.Base.cls

The most upvoted idea on the InterSystems Ideas Portal—garnering 74 votes—requests a lightweight version of IRIS. While the platform has grown into a powerful data engine, many projects require only its SQL database capabilities. This article demonstrates how to build an unofficial, compact IRIS Community Edition image focused solely on core database functionality, reducing the image size by over 80%.

⚠️ Disclaimer

This project produces an unofficial, experimental image of InterSystems IRIS Community Edition.

• Not supported or endorsed by InterSystems.
• Use at your own risk. The modifications remove core platform features and may break compatibility with tools, APIs, and expected behaviors.
• No warranties or guarantees apply, including fitness for production use.
• Intended only for educational and experimental purposes by advanced users.

Why a Lightweight IRIS?

While IRIS today includes rich functionality—interoperability, analytics, machine learning, system management, etc.—many projects only require its core SQL capabilities. The official Community Edition Docker image is approximately:

• Disk usage: 3.5–3.8 GB
• Compressed size: ~1.1 GB

IRIS Light reduces that to:

• Disk usage: ~575–583 MB
• Compressed size: ~144–148 MB

This makes it suitable for:

• Microservice or containerized SQL use
• CI pipelines with faster startup and pull
• Horizontal scaling where full features are unnecessary

There is a Master Table within IRIS that I am populating from Epic but want to share it with our Enterprise Application Development Team (Web). As a test I was able to use _SYSTEM from postman to execute the following.

POST /api/atelier/v1/xxxx/action/query HTTP/1.1
Host: xxxxxxxx
Content-Type: application/json
Authorization: ••••••
Cookie: CSPSESSIONID-SP-443-UP-api-atelier-=00f0000000000AKyLjBfUvU$MpFD8UT8y$EoNKNw1ixZeXN4_Q; CSPWSERVERID=hzZAT5rb
Content-Length: 86

{"query": "SELECT * FROM osuwmc_Epic_Clarity.DepartmentMaster WHERE ID = '300000000'"}

The demo is based on the raw class descriptions.
The data classes used are Address, Person, Employee, Company
For a more attractive demo, a JSONtoString method by ID was added.

Has anyone tried to authenticate IRIS client in Snowflake using Key Pair Auth as described in this doc?

I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

I was wondering if anyone had a way to automate creating the Query String for a FHIR Request?

Using HS.FHIRServer.Interop.Request in my development I have to specify the following...

I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?

I am trying to replicate a way to use FHIR as a way to query the EMR instead of using a MS SQL Stored Procedure that is populated via HL7 ADT to query.

I am looking for a way to capture Data Quality issues with the Source data that is populating HealthShare Provider Directory. 1 way is to use Managed Alerts, but since it could be multiple Providers and different messages it seems silly to alert on every message that has the error. Instead, I was thinking of using the Workflow Engine so it could populate a Worklist for someone to review and work.

Looking over the Demo.Workflow Engine example, I am not comprehending on how to send a task to the Workflow manager to populate the worklist from a DTL.

According to the Documentation  EnsLib.Workflow.TaskRequest has the following fields...

• %Action
• %Command
• %FormFields
• %FormTemplate
• %FormValues
• %Message
• %Priority
• %Subjext
• %TaskHandler
• %Title
• %UserName

I want to be able to capture the Source, Session ID, and any other Identifiers outside of the Error so it will show up on the Task List.

I am struggling how to build a csp template for me to be able to capture additional fields to send to the Workflow Operation.

Hi Developers!

Consider I have a persistent class derived from %Persistent and I want it to be derived from %JSON.Adaptor to enjoy all the JSON features.

Can I do it programmatically? 

So, it'd be wonderful to have a method in some util class that makes it happen? Something like:

Do ClassUtil.AddAncestor("MyPackage.MyPersistentClass","%JSON.Adaptor")

Any ideas?

You probably know this situation:
Some time ago, you found a very special $ZU function for a very specific type of problem. Some kind of mystical formula. It became popular and was used by many developers throughout your code and across all your installations.

Several versions and updates later, you are informed by ISC that your mystical $ZU is deprecated and no longer supported. You are advised to replace it with a new $something().

I built a BP, that every time that a message is received from a BS, it executes 

set isAuth=##class(%SYS.OAuth2.AccessToken).IsAuthorized("EpicFHIRPOC",,,.accessToken,.idtoken,.responseProperties,.error)
 if 'isAuth {
        set tSC=##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("EpicFHIRPOC", "*",, .error)        
         set isAuth=##class(%SYS.OAuth2.AccessToken).IsAuthorized("EpicFHIRPOC",,,.accessToken,.idtoken,.responseProperties,.error)
    }

When working with InterSystems Interoperability (Iris / Health Connect / Ensemble), configuration data is often spread across many production items: services, processes, operations, adapters, and their settings.

A common operational or security need is to answer questions like:

• Which interfaces reference file system paths?
• Where are directories, network shares, or absolute paths configured?
• Can I quickly audit or document this information across all my productions?

The ObjectScript utility below solves exactly that problem by exporting selected configuration settings into a CSV file.

Here is what is currently used.

..CurrentDateTime("%Y%m%d%H%M%S")

The format is not the issue.

I need to make it our current time as it is five hours ahead.

How can I access the header property of either of these.

Or, if I can't do that, subtract five hours or the equivalent time in seconds.

example, if I receive 20201224161922, how can I make it 20201224111922?

Thanks,

Jonathan
