Using JSON in IRIS

Saw the other day an article with the usage of the %ZEN package when working with JSON and decided to write an article describing a more modern approach. At some recent point, there was a big switch from using %ZEN.Auxiliary.* to dedicated JSON classes. This allowed to work with JSONs more organically.

Thus, at this point there are basically 3 main classes to work with JSON:

  • %Library.DynamicObject - provides a simple and efficient way to encapsulate and work with standard JSON documents. Also, there is a possibility instead of writing the usual code for creating an instance of a class like
set obj = ##class(%Library.DynamicObject).%New()

it is possible to use the following syntax

set obj = {}
  • %Library.DynamicArray - provides a simple yet efficient way to encapsulate and work with standard JSON arrays. With arrays you can use the same approach as with objects, meaning that yu can either create an instance of the class
set array = ##class(%DynamicArray).%New()

or you can do it by using brackets []

set array = []
  • %JSON.Adaptor is a means for mapping ObjectScript objects (registered, serial or persistent) to JSON text or dynamic entities.

Hi There,

I am having issues trying to obtain a JDBC driver which is backwards compatible with java 6 for a solution which will call my IRIS instance, I have already logged a WRC ticket which is looking unlikely that there will be any development to create a driver for such legacy tech.

The Java 6 app is end of life, however won't be replaced until after my project goes live, hence why I ask the question.

Hello,

I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.

I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).

The transformer is being used in a business process.

This is the code used in the transformer to encode the stream to base 64:

Debugging a SOAP web-client

Pointers please for debugging a SOAP web-client.

We have several clients in different productions all accessing a web-service. We are trying to add another client in a new production, and its not working. The messages between the relevant Process and the SOAP web-client Operation are the same in the working and the non-working productions. But the web-service is reporting an XML parsing error to the non-working production. Here's the error as reported in the SOAP web-client Operation...

FHIR Profile Validation Issues

Hello Community,

I've created my FHIR patient profile and POST into FHIR endpoint in Intersystems FHIR Server.

http:localhost:52773/fhirr4/StructureDefinition

I use the profile url into my Patient resource without the meet the profile requirements.

http:localhost:52773/fhirr4/Paient

The resource is stored successfully in the FHIR Server instead of a FHIR exception.

Why the resource doesn't validate with the mentioned profile?

Hello community, I need to solve a complex but trivial issue.

Given:

Two tables "Comment" and "Post". Each one contains an "Author" field, which is essentially a user ID. In these tables, each user ID represents an author. The goal is to count all participants together and then group them by month, language, and other metrics.

The question is how to do this within the IRIS ecosystem. Is it even possible to take two tables, get distinct data from them and then combine into one cube?

When you use VS Code to edit source code, the settings model allows you to specify folder-specific values for some settings by using a settings.json file located in a .vscode sub-folder of the workspace root folder. A value set here takes precedence over one from your personal settings when you are working within that workspace root folder.

InterSystems FAQ rubric

ObjectScript allows you to pass any number of arguments using arrays. Do it by adding ... after the argument name.

An example is as follows. In the example statement, the argument information is set in a global variable (a variable stored in the database) so that it can be easily checked after the method is executed.

Hi All! For those of you who are users of our cloud services, you may have been introduced to Health Connect Cloud. One topic within that cloud service that can be a little tricky is understanding how GitLab and the source control workflow fit seamlessly into your integration workflow in Health Connect Cloud. I recently presented a lightboard video explaining how this works, including the slightly different workflows for building interfaces via code versus building via the Management Portal UI. If you use Health Connect Cloud, let me know if this is helpful or if you have questions!
