#HealthShare

I have always struggled with Iterating through a JSON response to pull out certain fields into a Data Class Structure to use to populate fields in a DTL. So I defined the whole structure for the following JSON, with the base structure extending Ens.Response, %XML.Adaptor, and %JSON.Adaptor.

Who hasn't been developing a beautiful example using a Docker IRIS image and had the image generation process fail in the Dockerfile because the license under which the image was created doesn't contain certain privileges?

In my case, what I was deploying in Docker is a small application that uses the Vector data type. With the Community version, this isn't a problem because it already includes Vector Search and vector storage. However, when I changed the IRIS image to a conventional IRIS (the latest-cd), I found that when I built the image, including the classes it had generated, it returned this error:

Hey Community!

⏯  Taking the Fear out of FHIR - Fast Tracking Organizational FHIR Readiness @ Ready 2025

In my previous HttpRequests, I have used Content-Type = application/json but I have a vendor that is requesting we send application/x-www-form-urlencoded. How would I go about formatting the Payload as x-www-form-urlencoded?

Thanks

I've modified the class file, but messages still arrive as a single line (e.g., "H|.../rQ|.../rL") instead of separate lines in the ASTM service. The <ENQ>..<EOT> header looks correct, logs show no errors, and the service receives messages fine. Is there an Ensemble 2018.1 engine setting (like line terminator handling or TCP framing) to fix the line splitting? ​

When using InterSystems IRIS as an interoperability engine, we all know and love how easy it is to use the Message Viewer to review message traces and see exactly what's going on in your production. When a system is handling millions of messages per day, you may not know exactly where to begin your investigation though.

Over my years supporting IRIS productions, I often find myself investigating things like...

• What sort of throughput does this workflow have?
• Where is the bottleneck?

How can I programmatically retrieve a SQL query execution plan and analyze its results?

Job Title: InterSystems Developer / Specialist (IRIS / HealthShare)
Location: New York City, NY (Hybrid / Remote)
Duration: Contract (2+ years)
Experience: Min. 8 Years 

Job Summary

We are looking for an experienced InterSystems Developer / Specialist with expertise in InterSystems IRIS / HealthShare to support healthcare integration and interoperability initiatives. The ideal candidate should have hands-on experience in ObjectScript development, healthcare data standards, and integration protocols supporting EHR/HIE environments.

What is a FHIR Profile?

A FHIR profile is a collection of rules and constraints used to customize and refine a base Fast Healthcare Interoperability Resources (FHIR) resource. Profiling is a vital process that adapts the base FHIR resource standard to satisfy the unique requirements of a specific use case, geographic region, medical institution, or clinical workflow.

While the base FHIR specification provides generic, flexible definitions for resources (such as Patient, Observation, or Medication), profiles transform these generic resources into more precise ones. This ensures consistent and interoperable data exchange tailored for a particular community or implementation.

FHIR is designed to cover various healthcare scenarios globally. Profiles allow implementers to adapt this general platform without losing the benefits of standardization.

What is JWT?

JWT (JSON Web Token) is an open standard (RFC 7519) that offers a lightweight, compact, and self-contained method for securely transmitting information between two parties. It is commonly used in web applications for authentication, authorization, and information exchange.

A JWT is typically composed of three parts:

1. JOSE (JSON Object Signing and Encryption) Header
2. Payload
3. Signature

These parts are encoded in Base64Url format and concatenated with dots (.) separating them.

I'm generating a XML (Enlib.EDI.XML.Document) using a Subtransformation within a DTL. Writing this XML-Document to the filesystem works good, but in the XML-File is missing the header line (<?xml version=1.0 encoding=UTF-8?>):

What do I have to do to get the header in my XML-File?

Any help is appreciated.

New to using Analytics and using Dashboards. We have this Report, SQL Query that lists out the Activity per Data Source in Health Share Provider Directory. Instead of running it as a report, because it takes a while to run, was wondering if there is a way to do this as a Dashboard instead.

How can I take the SQL from this report and create a Dashboard instead?

I have a business service that actively reads data from a remote Postgres database. OnProcessInput opens a XDBC (actually JDBC) connection, executes an SQL query, fetches several thousand rows, iterates the resultset, and closes the connection. On each iteration I also need to update each source row in the remote database using PreparedStatement.

In other words, in every OnProcessInput call I have a long running SELECT statement and several thousands small UPDATE statements.

InterSystems IRIS is built on an architecture that separates the logical organization of data (namespaces) from its physical storage location (databases). Understanding this separation and the distinction between Namespaces and Databases is crucial for effective data management, security, and especially, high-performance data sharing.

In this article, I will discuss these foundational components and provide a practical guide on leveraging global mappings to share native data structures (globals) across different logical environments.

Databases: Physical Reality

A database represents the physical reality of where the data is stored on the disk. First and foremost, it’s a file in a file system called IRIS.dat (e.g., <Install folder>\mgr\user\IRIS.DAT). The maximum size of this file is 32TB. It is the container for all the actual data and the code. Databases are managed by the IRIS kernel, which handles caching, journaling, and transaction logging at the physical file level.

When you install InterSystems IRIS DBMS, the following databases are installed automatically:

Could someone help me with this error?

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 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.

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

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.
