Reference for the JSON Web Classes

Foreword

InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.

IntegratedML hands-on lab

Have you tried the InterSystems learning platform lab for IRIS IntegratedML? In that lab you can train and test a model on a readmission dataset and be able to predict when a patient will be readmitted or not, or calculate its probability of being readmitted.

You can try it without any installation on your system, all you have to do is start a virtual lab environment (Zeppelin) and play it around!

Caché vs Cache

I see that there is an "Insert Special Character" option from the text editor where "é" can be selected, but would it be possible to create a "Caché" button that inserts the word "Caché"? I can see cases where mixing these words can be confusing. An even more important reason would be searching. If the word "Cache" is used instead of "Caché" in many places, it may be difficult to find information about the "Cache".


If a "Caché" button existed, it may encourage the correct spelling to be used. I am not sure if this is a real problem, but I see the possibility of it happening.

Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass

Problem

In a fast-paced clinical environment, where quick decision-making is crucial, the lack of streamlined document storage and access systems poses several obstacles. While storage solutions for documents exist (e.g, FHIR), accessing and effectively searching for specific patient data within those documents meaningfully can be a significant challenge.

I'm currently working with a developer to add IRIS/Caché functionality to his HL7 analysis tool that would allow its users to extract messages directly from the Ensemble message store. IRIS for Health Community Edition has been a great aid in debugging this, but I keep banging into the 5 connection license limit with Studio, the Management Portal, an IRIS terminal session and a client database connection using either ODBC or ADO.NET.

Ensemble scheduler

Hello!
We have had incidents with the scheduler in some integrations.
The problem is that the scheduler do not execute at seemingly random occasions.
Has anyone else experienced this? If so how have you handled it?
Is there a smart way to be informed about these non events.
I have an idea to build an integration that goes thru all the other integrations, looks at their schedules and compare it with lastrun information in someway but I am not sure if it is doable.

Driver odbc performance

Hello,

I'm using the InterSystems Iris odbc driver (DriverODBCVer=02.10) to get data from Iris table but it is slow.

Is there any options to improve performance ? Increase the packet size ?

Change to do in odbcinst.ini / odbc.ini to make it quicker ?

Thanks

Hi,

We are using IRIS, and have some systems that we send data to that cannot accept messages with certain fields larger than a particular size.

Is there any way to utilize the schema to truncate any fields that are larger than the entered data?

I've tried just setting the max lengths and doing the transform, but it puts in the entire string, and can't find a topic for it.

There are a large number of fields that need to be truncated, so it would be ideal to get it to respect the hl7 schema maximum lengths.

Hello, I've checked past posts and don't see the answer. Hope someone can help.

I'm working with our commercial version of VistA. Cache 2016.2.

I've connected to the instance and copied a few M routines to my local Atelier project. I edited a comment in the file and attempted to save/compile the routine back to the server.

I'm getting

Synchronization failed: Invalid header in /Encounter Interface/VFD.......

Is there something I'm missing? Thanks in advance.

Annotating PDF files

I've been asked to annotate a PDF file (in Intersystems Cache). That is, take in an existing PDF (printable form with areas for people to write in) and use Cache to update it (automatically fill the fields in).

Does Zen have the ability to set a starting/initial PDF? I see the ability to define an XML format to write in, but that's not exactly what I need, because that will generate my "answers".

I'd like to overlay my "answers" on top of an original PDF. Do you know how to do that?

Hi Developers, I'm currently doing a demo about building a front end UI doing data analytics and setup a performance test with large data objects, therefore using "Populate Utility" could help me auto generate some sample data that I can play with.

Within this post I would like to share my experience of using Populate Utility, including using POPSPEC Parameter.

Oauth 1.0 library

I am in need of a routine or class method to generate an Oauth 1.0 signature. I was about to code this myself, but thought to check first to see if anyone has already done this and is willing to share.

Thanks in advance for any help.

Byte[] property type

One of the REST APIs we need to call takes one of request parameter as a byte array. I am trying to create a message class and couldnt figure out which is equivalent type that corresponds to Byte[]. I need to read from a jpg file and then convert it to byte[] before i invoke this webservice. Appreciate if anyone can point me in the right direction. I can use %Stream.FileBinary class to store the jpg file after loading from a file. trying to figure out how to convert that to byte[].

The productions are components developed with InterSystems IRIS Interoperability module to promote integrations between systems, data sources/targets, web services, API, message channels, etc. Productions are composed by:

1) Business services to get/ingest/get data events or requests;

2) Business operations to send or persist data to repositories, systems, API, web services, etc; and

3) BPL - BPEL flows to orchestrate, mediate, compose and route data from business services to business operations.
