FastJsonSchema: High-Performance JSON Validation in IRIS

Validating JSON data against JSON Schema is a common requirement for modern applications. FastJsonSchema brings this capability natively to InterSystems IRIS, combining speed, simplicity, and full schema compliance.

Unlike traditional validation approaches, FastJsonSchema generates native ObjectScript code from your JSON Schemas and compiles it directly to iris object code, enabling idiomatic performance without relying on external libraries or runtimes.

Use IRIS Load Data in VSCode

The Load Data utility it is an excellent tool to load data from CSV/TXT files into an IRIS SQL Table, but it is required send the target file to the IRIS server and write the Load Data sentence to ingest the file content. Now it is possible select a file in VSCode, set the table destination and submit the request. The vscode-load-data utility will send the file to the IRIS server and run the Load Data command to you! Very simple:

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

Does anyone have a query that I could run to show a Vendor the time difference between when a message was sent out a BO, and when we received the HL7 ACK back that is associated with the message sent?

I am trying to prove to this vendor of the delay we are seeing getting the ACK back because of a Timeout

I know how to pull Ens.MessageHeader, and EnsLib.HL7.Message but not sure how to match up the Message with the HL7 Acknowledgement received.

Hi,
I have a code that copy a method to another class for analysis purpose.

I also want this method to appear first in the source code to easily use it in VSCode with the classmethod debug button and not search it in the numerous method of the modified class.
Is there a way to do such a thing?
I tried the placeAfter keyword but I can't find a way to make it really work as I want. Is their other ways to control the order of methods?

Error in iris-rag-demo

I cloned iris-rag-demo from Open Exchange and issued docker-compose up -d. I went to the front end and type in the chat message:

RecordMap Data Validation

I am trying to add some validation to an existing Record Map, because recently we had some wrong data get consumed into the System and is causing all kinds of havoc.

Using the AI on the Developer community it suggested that I use PATTERN within the Datatype Parameters to force some validation on some fields. I have never used PATTERN before...

When I go to generate the updated Record Map, I am getting the following...

My problem was separating HL7 messages by message type. I had to create multiple File Operations. So I with custom code I am able to use 1 File Adapter for 1 interface and multiple message types. I did experiment pulling the MSH 4 out of the raw content to further access dynamic information, but that may open a need for more robust error checking / lookup default actions.

Using the recommended naming convention of "To_FILE_<IntegrationName>"

I decided to use a generic file name and path in the default settings.

good afternoon!

I was trying to set up the "File Spec" to match the exact filename that will be in the file path.

however, it seemed grab whatever the name of the file and work on it.

wondering how I can specific the exact filename in "File Spec" so that It wont touch other files in the same path?

I have a class that extends %CSP.REST which made I deployed using $system.OBJ.MakeClassDeployed. After upgrading IRIS, the web app which uses that class no longer works with an ObjectScript error.

In the past, I fixed that problem by adding a dummy new line or a comment then recompiled that class. For this deployed class, I can't add a new line and recompile the class (the code shows up as locked in Studio). Simply running $system.OBJ.compile() is not fixing the web app issue.

Is there a way to edit a deployed class then recompile it?

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?
