I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.
Occasionally. we get questions about using OpenEHR with InterSystems. Typically, these discussions focus on why and how an organization wants to implement OpenEHR in building applications. Here’s a brief guide:
If there is a way we can find how much a particular namespace is utilizing the O/S CPU and memory, that will be great in resource utilixation as well as capacity planning.
The competition was filled with outstanding articles, each showcasing innovation and expertise. With so many high-quality submissions, selecting the best was no easy task for the judges.
Let's meet the winners and look at their articles:
Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)
I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date
Select Sum(MsgCount)
From
(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount
What is the SQL table name for it? How can I obtain it via ObjectScript?
A quick search doesn't show any methods and properties. Documentation is a bit "wrong" here saying that the SQL table name is the same. It will be at least 'x_y.z'.
I'm working on a requirement to loop through all encounter streamlets(SDA) to identify specific encounters based on an encounter extension property for a patient fetch request. However, this current process is time-consuming, and we need to create indexes for that property to quickly retrieve the expected results without going through all the encounter streamlets of a patient.
I would appreciate help on how to achieve this, as I couldn't find any documentation explaining how to create indexes on a SDA element.
We are calling a REST web-service from Ensemble using EnsLib.HTTP.OutboundAdapter and redefining the adapter class to set custom headers as described by @Eduard Lebedyuk here: How to set Content-Type
We recently changed the 'UserID" property in a "User" class from type of %String to be %Library.Username. This is for better consistency across our codebase regarding MAXLEN limit.
%Library.Username is a system wrapper datatype which extends %String and has a MAXLEN of 160. This change should have minimal/no impact on code behavior. However, we found that some SQL query cannot return expected rows after the change. Query will return empty values even if the entry is in the table.
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.
I need to read a directory on a remote server which requires a user to be su.
The question is how to correctly read the server response and then to send a su password using IRIS device I/O API (I'm able to read other commands output such as uname, but can't figure out how to switch to su):
The FHIR standard establishes a powerful but flexible data model that can smoothly adapt to the complexities of operational healthcare data management. This flexibility comes at the cost of a data model with many tables and relationships, even for simple data such as the patient's record of telephone numbers, addresses, and emails. It would easily require querying 4 different tables. However, FHIR SQL Builder eliminates this problem, allowing you to create visual projections (mappings) in web wizards.
I would like to convert an html zen page to PDF using wkhtmltopdf so I've installed it in Ubuntu and the command wkhtmltopdf but because I've my IRIS installed in a container that command is not recognized and we can't install wkhtmltopdf in the container so is there a way to be able to run this command?

I'm experimenting with FHIR bulk data load using NDJSONs, so far the import is running smoothly, but when I'm trying to perform a request of kind /Patient or /Procedure I'm getting back the following error:
Unlike the movie mentioned in the image (for those who don't know, Matrix, 1999), the choice between Dynamic SQL and Embedded SQL is not a choice between truth and fantasy, but it is still a decision to be made.Below, I will try to make your choice easier.
If your need is interactions between the client and the application (and consequently the database), Dynamic SQL may be more appropriate, as it "adapts" very easily to these query changes.However, this dynamism has a cost: with each new query, it is remodeled, which can have a higher cost to execute.Below is a simple example of a Python code snippet.
As the health interoperability landscape expands to include data exchange across on-premise as well as hosted solutions, we are seeing an increased need to integrate with services such as cloud storage. One of the most prolifically used and well supported tools is the NoSQL database DynamoDB (Dynamo), provided by Amazon Web Services (AWS).
I am an architect working on a program involving Weblink. I am new to InterSystems and I am looking for information around basic capabilities of Weblink. I understand that the version we are dealing with (2014) is not supported no need to review that :).
As you can see the new topic of the programming contest - AI Agents.
The topic was over-hyped recently on the Internet and has different meanings. You might get curious about what we mean by AI agents in regard to the InterSystems programming contest.
