I have a transformation that the incoming schema is an XML file and I will need to write multiple HL7 transactions. Is there anyway to do this?
Hi
We receive an HL7 order message into our integration engine containing OBX segments. I would like to create a PDF file and take the values from all instances of OBX-5 in the message and write them to that PDF file, which I would then like to embed into an outgoing message to another system.
Any help appreciated.
Thanks
Frances

A storm of applause goes to these developers and their applications:
Hi Community,
Learn how to use validation tools in InterSystems IRIS to assess and validate the behavior of a production:
There are couple of options to do this.
1. You can extend your class &JSON.Adaptor, it will do it for you with inbuilt logicaldtodisplay methods
2. Create another request class and do your transformations
3. Before calling the json convert to stream methods, transform the object's field with a ZDT.

I have an extremely simple example where there is a class with 3 properties
Hi Developers,
Thanks to all who participated in our competition for your awesome ideas of applications that can be developed in 2021. See what a great list of ideas you all created! Now it's time to announce the winner:
Meet the Author of the Best Idea: @Yuri Marx 👏🏻👏🏻👏🏻 Congratulations!
💡 Yuri's idea: "HTML 5/Node.js documentation generator app, based in markdown and with the option to execute ObjectScript class methods like a developer portal. It is not to swagger API, but to Object Script".
Yuri gets our special prize: a personalized handmade leather wallet.
See the complete list of ideas in the comments to this post. You are very welcome to leave more of your ideas! We hope this list will bring inspiration to all of you.
I have implemented a web service that inherit from %SOAP.WebService
It exposes classes with string properties :
Class Employee Extends (%RegisteredObject, %XML.Adaptor) [ ProcedureBlock ]
{
Parameter XMLNAME = "Employee";
Parameter XMLSEQUENCE = 1;
Property FirstName As %String(MAXLEN = "", XMLNAME = "FirstName") [ Required ];
Property LastName As %String(MAXLEN = "", XMLNAME = "LastName") [ Required ];
...Here is the issue: those properties are filled from a huge Caché database which contains forbidden XML characters (usually control characters in the 0-31 range).

Hi all,
I added an additional shard node to an existing shard by accident.
After the add, it can not be removed and query from the master shard now fails. I did not find any data from shard master in the shard node.
How to recover it and remove the shard node from the shard master?
Thanks.
Hi guys.
That time I'll show you a way to use a machine learning model implemented using IntegradeML as source for an IRIS analytics cube dimension.
Creating the ML model:
Execute this SQL in order to create a new ML model using IntegratedML SQL extension:
CREATE MODEL AppointmentsPredection
PREDICTING (Show)
FROM (SELECT
Canal,
CreacionDate,
CreacionHora,
Edad,
Especialidad,
Latencia,
ReservaDate,
ReservaHora,
Sexo,
Tipo
FROM dc_myapp_model.MedicalAppointments
Now, you can train you model:
The question has come up several times and I saw mixed answers and no quick example
My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()
e.g.
- your servers IP address or addresses depending on your configuration.
- pinging any other server to see if it is still visible on the network
- running nslookup

Good day, Developer Community!
As you know we have Company listings on Open Exchange. It lets publishing Open Exchange applications on behalf of companies so one can check which solutions in certain industries are being provided by companies.
Sometimes people are also looking for qualitative and proven implementation or consulting services on InterSystems products: IRIS, Caché, Ensemble, or HealthShare.
And recently we introduced a new option on Open Exchange to list the services your company provides related to InterSystems technology: implementation, consulting etc.
How to do that?
Open your company profile in the Services tab and create a service. Choose the type of service and give a description of what the service is about and why it is worth ordering it. Instructions.
Then publish the service by sending it for approval.

The InterSystems IRIS has two major paths to a digital service: API/Web Service into Interoperability module and multimodel Database/Analytics. Each of them has your security configuration.
To do API security you apply an OAuth or JWT plug-in to the API endpoint. So in the Admin Portal, API producer and consumers get the keys to authenticate the API and consume it. The Admin Portal allows you configure RBAC policies too.
Did you know that you can get IRIS Analytics features as an REST API?
In this article I'll show some endpoints of IRIS Analytics Business Intelligence REST API, used in my project iris-analytics-notebook to create a pivot table component in Angular.
Getting all cubes in namespace
Method: POST Endpoint:
/api/deepsee/v1/:namespace/Info/Cubes
Example:
http://localhost:52773/api/deepsee/v1/myapp/Info/Cubes

Hi everyone,
It's the bottom of the 9th inning, but I have a few more plays to make in our technical World Series ![]()
The InterSystems IRIS has a very nice container class to allows you have your Dashboards as classes source code. It is %DeepSee.UserLibrary.Container.
With this class is possible group all your dashboard and pivot table definitions.
This is useful to automatically create your dashboards when you build your docker project and other automation scenarios.

Today, is important analyze the content into portals and websites to get informed, analyze the concorrents, analyze trends, the richness and scope of content of websites. To do this, you can alocate people to read thousand of pages and spend much money or use a crawler to extract website content and execute NLP on it. You will get all necessary insights to analyze and make precise decisions in a few minutes.
Gartner defines web crawler as: "A piece of software (also called a spider) designed to follow hyperlinks to their completion and to return to previously visited Internet addresses".
Hello guys.
Can anyone help me about Global ^Errors? Only in 1 specific namespace is it growing fastly. It grows from 2 to 3 Gb per hour when all services are active. Which commands exactly do this? In another similar namespaces, there is not that Global in the class list.
Thanks.
Hi guys!
I'd like to present you my new project: iris-analytics-notebook, a notebook approach to use IRIS analytics capabilities.
Project description
In past few years, notebooks tools like Jupyter are gaining popularity due its natural way to express ideias.
An almost unipresent tool for data scientists, notebook can also help to improve the impact of analytics tools for all sort of users.
This project is my attemp to implement a simple notebook system, combining IRIS Analytics capabilities, with a custom notebook system - largelly inspired by Jupyter notebooks.
With this project you can:

Hello,
I am trying to use %ZEN.proxyObject to send out in JSON format so I do:
set tProxyRequest.notanumber = "28001"
set tProxyRequest.aboolean = "true"
set tBody = ##class(%GlobalCharacterStream).%New()
do ##class(Ens.Util.JSON).ObjectToJSONStream(tProxyRequest,.tBody,"aelotwu")
w tBody.Read()
and I get:

"aboolean":"true",
"notanumber":28001
}
But I want this:
