Hi Community!

Please welcome the next video from Global Summit 2019 on InterSystems Developers YouTube:

⏯ Implementing FHIR Use Cases

It would be interesting if there is some recommended documentation about best practices using Healthshare for interoperability.

Also, some how-tos or frequently asked questions about ObjectScript.

Or event better, if there are experienced developers who would like to share some common habits on their work with Studio / ObjectScript, which are valuable to do the developing work better.

For example, How to get the XML of a class and write it into a REST operation:

...

Method X(pRequest As Mensajes.ServiciosGeneralRequest, ...){

set writer=##class(%XML.Writer).%New()
set status=wri

This is a sample to use %JSON.Adaptor class available in IRIS to produce a snapshot of your object.

The sample consists of 2 classes that are variations of what was known in Caché/SAMPLES as Sample.Person.
Be aware that the possibilities are limited by %JSON.Adapter and how you make use of it.

Once in place, you create some test data by Populate().
You select an object and take a snapshot.
You apply changes to your object and take another snapshot.
And see the difference.

BINGO!

GitHub

It's also an example of a customized SystemFunction extension (ZZISJSON) in Caché & IRIS
This time it is to be included in %ZLANGF00.mac

A JSON string is mostly imported from a file or over REST
You rely on a clean and compatible structure. This is the check.

required: ZPretty.mac

demo

USER>ZWRITE jsn  
jsn="{"Name":"Li,Robert K.","SSN":"672-92-9664","DOB":"1975-01-12","Home":{"Street":"986 Washington Blvd","City":"Boston","State":"PA","Zip":"95802"},"Office":{"Street":"6012 First Place","City":"Reston","State":"MT","Zip":"77739"},"Spouse":{"Name":"Avery,Zelda H.

t's also an example for a customized command extension (ZZJSN) in Caché & IRIS

This is the Caché version for fast JSON formatting but it also works in IRIS.
Requires package ZPretty
To allow parallel existence in IRIS this is named ZZJSN

see:

USER>ZWRITE jsn  
jsn="{"Name":"Li,Robert K.","SSN":"672-92-9664","DOB":"1975-01-12","Home":{"Street":"986 Washington Blvd","City":"Boston","State":"PA","Zip":"95802"},"Office":{"Street":"6012 First Place","City":"Reston","State":"MT","Zip":"77739"},"Spouse":{"Name":"Avery,Zelda H.

Hi,

Recently I have encountered a new issue, more and more 3rd party applications move to the cloud.

Web-hooks incoming from their sites can no longer be identified using a known and fixed IP address, so our customer's security department blocks them.

In past similar cases we use to grant access in the customer's Fire-Wall to the specified IP address - this is no longer applicable.

Has anyone else encountered this problem ? do you have any ideas ?

Thanks

t's also an example for a customized command extension (ZZJSON) in IRIS

IRIS has a nice %JSON.Formatter class.
But for debugging it is not really handy.
see:

ZWRITE js1  
js1="{""Name"":""Cunningham,John C."",""SSN"":""294-11-9150"",""DOB"":""1933-01-08"",""Home"":{""Street"":""4249 Ash Street"",""City"":""Tampa"",""State"":""MD"",""Zip"":""30176""},""FavoriteColors"":\[""White"",""Red"",""Green""]}"   

so you proceed for the most simple case

set formatter=##class(%JSON.Formatter).%New()   
do formatter.Format(js1)  
{   
  "Name":"Cunningham,John C.

Henry Elliott is currently recruiting for Sr. Developers with InterSystems technology stack experience including Cache, IRIS for Health, HealthShare, Ensemble.

It is a classic Global Mapping exercise presenting ^SPOOL as Class / Table

Background

Device #2 named SPOOL dates back to the predecessors of Caché and IRIS
It was the first "%Stream" like option to buffer output before printing.
It is also the first and till today the most simple way of output redirection.

Solution

This is also an example of a mapped Global.
USE 2 redirects the output into the Global ^SPOOL

You can read the global manually or with some ancient utilities
or use this mapping to access it as class or a SQL table.

Hi,

I am attempting to set up a security role for our support team so they can have read access to the production and messages.

I have given the role RW rights on the resource associated with the database. However, when I log into Management Portal and select "Ensemble", the "Available Ensemble namespaces" list is empty.

What permissions do i need to set to be able to navigate to the production?

Hi

What would be the best way to restrict use of a set of SOAP services so that they could only be called from specific white-listed IPs?

Thanks

This is my introduction to a series of posts explaining how to create an end-to-end Machine Learning system.

Starting with one problem

Our IRIS Development Community has several posts without tags or wrong tagged. As the posts keep growing the organization of each tag and the experience of any community member browsing the subjects tends to decrease.

First solutions in mind

We can think some usual solutions for this scenario, like:

• Take a volunteer to read all posts and fix the mistakes.
• Pay a company to fix all mistakes.
• Send an email to each post writer to review the texts from past.

The guide “Extending Languages with %ZLANG Routines”
Tells you all details you need to know to extend your programming language.
EXCEPT: How to do it in a clean way.

This example of a %ZLANGC00.mac may show a possible approach
to get an easy to overview and to manage setup.
With less than 50 lines of code you might not be affected.
But if your Studio shows close to 1000 rows or more you may get in troubles.

My recommendation is simple.
Instead of adding line-by-line commands and it's code
you isolate each command and its code into a separate Include file.

Sapphire has CSV import, create and train IntegratedML model and I will create more features. See the pool. Check sapphire in https://openexchange.intersystems.com/package/SAPPHIRE

Hey Developers!

This week is a voting week for the InterSystems IRIS AI Programming Contest!

So, it's time to give your vote to the best AI- and ML-enabled solution on InterSystems IRIS!

🔥 You decide: VOTING IS HERE 🔥

How to vote? This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

IRIS and Caché / Ensemble offer the possibility to add Languages Extension as SystemFunctions,  SystemVariables,  SystemCommands

The related documentation tells you where to add the system-wide extension. Parameter passing is not covered explicitly.

Currently, the process of using machine learning is difficult and requires excessive consumption of data scientist services. AutoML technology was created to assist organizations in reducing this complexity and the dependence on specialized ML personnel.

AutoML allows the user to point to a data set, select the subject of interest (feature) and set the variables that affect the subject (labels). From there, the user informs the model name and then creates his predictive or data classification model based on machine learning.

Hi Developers,

Please welcome the new video, specially recorded by @José Pereira for the InterSystems IRIS AI Programming Contest: 

⏯ Monitoring your ML model with IntegratedML

Hi Team,

When I tried to open ensemble in my system I got bellow error.

I have done lots of code in my local system but now not able to open the ensemble.

GA releases are now published for the 2020.2 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

A full set of containers for these products are available from the WRC Software Distribution site, including community editions of InterSystems IRIS and IRIS for Health.

The build number for these releases is 2020.2.0.211.0.

InterSystems IRIS Data Platform 2020.2  provides an important security update with the following enhancements:

• Support for TLS 1.3
• Support for SHA-3

InterSystems IRIS for Health 2020.2 includes all of the enhancements of InterSystems IRIS.

This is the second post of a series explaining how to create an end-to-end Machine Learning system.

Exploring Data

The InterSystems IRIS already has what we need to explore the data: an SQL Engine! For people who used to explore data in csv or text files this could help to accelerate this step. Basically we explore all the data to understand the intersection (joins) which should help to create a dataset prepared to be used by a machine learning algorithm.

What is the sql command to describe table in cache db.

I send ORUs to a process where a transform is applied before sending the message to a process where the routing is handled. A recent request was made that when OBR:25="D" the message is also be faxed with transforms that have some similarities to the original, but not exactly the same. I copied the DTC, made the alterations, and created a separate rule to handle it. However, when I run a message through with a "D" in OBR:25, it is only sent to the routing process once.

Hi Community,

Please welcome the new video, specially recorded by @Renato Banzai for the InterSystems IRIS AI Programming Contest: 

⏯ IRIS ML Suite Demo

Following up the previous part, it's time to take advantages for IntegratedML VALIDATION MODEL statement, to provide information in order to monitor your ML models. You can watch it in action here

The code presented here was derived from examples provided by either InterSystems IntegragedML Template or IRIS documentation, my contribution was mainly mashing up such codes. It's a simple example intended to be a start for discussions and future works.

Note: The code presented here is for explanation purpose only.

A few months ago, I read this interesting article from MIT Technology Review, explaing how COVID-19 pandemic are issuing challenges to IT teams worldwide regarding their machine learning (ML) systems.

Such article inspire me to think about how to deal with performance issues after a ML model was deployed.

I simulated a simple performance issue scenario in an Open Exchange technology example application - iris-integratedml-monitor-example, which is competing in the InterSystems IRIS AI Contest. Please, after read this article, you can check it out and, if you like it, vote for me!

InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time.

We understand, however, that for testing and other specific purposes, you may want to run InterSystems IRIS-based containers from InterSystems under Docker for Windows.

Hey Developers,

New "Coding Talk" video was specially recorded by @Yuri Marx for the InterSystems IRIS AI Programming Contest: 

⏯ SAPPHIRE - AutoML UI to InterSystems IntegratedML

Let's say I have this simple script  file try.script

write 1
write 0

I can execute it in a terminal (csession) by calling:

csession cache < try.script

And I get the following output:

%SYS>
1
%SYS>
0

However I want to use a try catch block in my script:

try {
write 1/0
catch {}
halt

But as script is executed line by line, it's interpreted like this:

%SYS>
TRY {
      ^
<SYNTAX>
%SYS>

WRITE 1/0
^
<DIVIDE>
%SYS>

CATCH {}
^
<SYNTAX>
%SYS>

I know that I can write it all in 1 line, but I'd rather not do that. Is there a way to feed multiline statement into Cache?
