HL7 -> SDA -> FHIR -> Personal Growth

I have a large tree outside my window. Here in Phoenix, Arizona, USA it's still warm and sunny so our plants are still covered in lush foliage despite so many other places in the full throws of Autumn. My desk is oriented such that I can look out at the tree throughout the day.

I am trying to help another group within our organization access a SQL Table that I have created to populate Epic Department Data within our environment and came across the ability to use SQL Seach REST Interface using iKnow.

However, I am having issues trying to get it to work via POSTMAN before I hand off the solution...

the POST URL... https://<servername>/api/iKnow/latest/TESTCLIN/table/osuwmc_Epic_Clarity.DepartmentMaster/search

where osuwmc_Epic_Clarity.DepartmentMaster is the table

In the body...

Often times when working with FHIR data, for example with IRIS For Health, you'll find it useful to create a custom FHIR operation. The FHIR Standard comes with a set of defined operations (such as $everything) but a custom operation comes in handy when you need to create some extra functionality that goes beyond the set of standard FHIR operations.

We have a task that runs objectscript code to load data into a linked external table. After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message. The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is. The result is the same with and without the USING clause, so don't let that confuse you. We have logs of this statement succeeding before upgrade, and were able to get this statement to work in our production environment, which is still on version 2

InterSystems FAQ rubric

Mirroring only synchronizes database files.

To synchronize other files required for your application (CSP files, images, documents, etc.) between the two servers that make up the mirror set follow one of the approaches:

  1. Place those files on a shared disk by introducing a NAS or similar device
  2. Or use file sync software to synchronize files between two servers.

Hi Everyone, I'm Prakash Hinduja, a financial advisor and consultant. My roots in India now living in Geneva, Switzerland (Swiss). I'm looking for some suggestions on how to get the best performance from Adaptive Analytics 2023.2. I know it uses Adaptive Parallel Execution and automatic aggregates, but I'm curious if you've found any other tips or tricks. For example, are there any specific data modeling choices or system configurations that have worked well for you? I'm trying to make our cubes as responsive as possible. Thanks in advance for any insights!

Regards

Hi folks!

Sometimes, when designing a class method and feeding it with more and more useful features, very soon the number of parameters can reach 10 and even more.

It becomes pretty difficult for users of useful methods to remember the position of the important parameter, and it is very easy to misuse the position and transfer the wrong value to the wrong parameter.

Here is an example of such a method (I asked GPT to create a method with 20 params):

ClassMethod GenerateReportWith20Params(
    pTitle As %String = "",
    pAuthor As %String = "",
    pDate As %String = "",            // e.g. 2025-09-03
    pCompany As %String = "",
    pDepartment As %String = "",
    pVersion As %String = "1.0",
    pFormat As %String = "pdf",       // pdf|html|docx
    pIncludeCharts As %Boolean = 1,
    pIncludeSummary As %Boolean = 1,
    pIncludeAppendix As %Boolean = 0,
    pConfidentiality As %String = "Public",
    pLanguage As %String = "en",
    pReviewers As %String = "",       // CSV, e.g. "Alice,Bob"
    pApprover As %String = "",
    pLogoPath As %String = "",
    pWatermarkText As %String = "",
    pColorScheme As %String = "default",
    pPageSize As %String = "A4",
    pOrientation As %String = "Portrait",
    pOutputPath As %String = "report.pdf"
) As %Status
{

// implementation
}

Hi Guys,

I get the below error when trying to compile an imported class in IRIS, it compiles if I remove [ Collection = list ] so not sure about the use of [ Collection = list ] and if removing it would affect anything and its just a duplication?

I created a Custom Search Table that extends EnsLib.HL7.Search Table. I saved, compiled, and rebuilt the index however when I go into Message Search to try to use the Search Table, within the conditions the proper fields are not showing up that was defined. It is showing the fields from EnsLib.HL7.SearchTable. I did a build index on both EnsLib.HL7.SearchTable and OSU.HL7.SearchTable.

Greetings,

As a long time Cache developer is there a way to get a copy of the Cache Studio that supports IRIS 2024.3? I do not have a WRC account? I need Studio just to experiment, not to build commercial software.

Thank you,

Everardo

Customer support questions span structured data (orders, products 🗃️), unstructured knowledge (docs/FAQs 📚), and live systems (shipping updates 🚚). In this post we’ll ship a compact AI agent that handles all three—using:

  • 🧠 Python + smolagents to orchestrate the agent’s “brain”
  • 🧰 InterSystems IRIS for SQL, Vector Search (RAG), and Interoperability (a mock shipping status API)

Studio's Find In Files finds nothing if CLS routines are included. The error is WIDE CHAR. After using ##class(%Studio.Project).FindInFiles programmatically and then ZW after the same error I strongly suspect that CodeWalkopdatecopyopt in EnsLib.InteropTools.HL7.Cloverleaf.Parser.cls is to blame. I cannot even open this class, unlike other classes from EnsLib.InteropTools.HL7.

As part of a recent documentation technical project to optimize the search, I needed to use Embedded Python in my ObjectScript code. The main blocker was passing a Python list from a Python class method to a ObjectScript method. Sending the list by reference to the python method, populating it with the Insert() method, and returning the reference to the ObjectScript method resulted in an list with type %SYS.Python, a process that was straightforward but not efficient.

I had a need for a Filter, but did not want to recreate the wheel by creating another Data Lookup Table, so instead I created a Linked Table that points to a MS SQL Table outside of IRIS.

Once I had the Linked Table, I created a Class Method Function that would query the Linked Table and return a 1 if a result came back.

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?

What are best practices for JSON transformation in IRIS interoperability? This is for a non-healthcare use case, so any tools we happen to have around FHIR might not be available. The motivating use case is trimming down a verbose and needlessly complex REST API response to feed to an LLM - trying to reduce token usage and maybe get better results from less noisy data.

Hi folks!

It is very easy to import CSV data into IRIS. But what if we want to preserve the original IDs in CSV?

Recently I came across with the situation when I needed to import two csv's into IRIS which were linked by one column referencing to another csv's col: a typical Foreign Key and Primary Key situation, where csv1 contains this column as Primary Key, and csv2 as Foreign key with id's related to csv1.

The image is generated by ChatGPT so don't blame it - it tried its best to generate countries as primary keys with countries.csv-cities.csv relationship :)

I have a need to create a specific Search Table outside of the EnsLib.HL7.SearchTable specifically for HL7 MFN messages in HealthShare Provider Directory.

Our Code is created in a different namespace then the main HSPD namespace and is mapped within the HSPD namespace mapping.

I created a copy of EnsLib.HL7.SearchTable, named OSU.HL7.SearchTable what all needs mapped to make this new search table available in HSPD namespace?
