I would like to know any experience working with OPC UA standard in industry sector or IoT. Currently there is no adaptor implemented in IS IRIS for it but it seems to be pushed as the main standard in industry. Did anyone had to implement their own libraries or adaptors to deal with it? Or do you advice to use any already implemented library in Java, Python,...? Any feedback would be appreciated.

make debug in C#

coming back , and re-load again in Caché.

Hi All,

Actually, I'm developing few restful API's. I want to create a authentication tokens and display it on my login restful API. If I'm using CSP sessionId, how can I validate the session Id's in another or continues restful API's. else, is there any other approach to handle this task.

My Primary goal is, I have to integrate 2 different front end applications. One is Zen framework another one is web pages from Python.

If any lead, it would be appreciated.

Thanks,

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

REST Design and Development

Intro

For many in today's interoperability landscape, REST reigns supreme. With the overabundance of tools and approaches to REST API development, what tools do you choose and what do you need to plan for before writing any code?
This article focuses on design patterns and considerations that allow you to build highly robust, adaptive, and consistent REST APIs. Viable approaches to challenges of CORS support and authentication management will be discussed, along with various tips and tricks and best tools for all stages of REST API development. Learn about the open-source REST APIs available for InterSystems IRIS Data Platform and how they tackle the challenge of ever-increasing API complexity.
The article is a write-up for a recent webinar on the same topic.

Load a ML model into InterSystems IRIS

Hi all. Today we are going to upload a ML model into IRIS Manager and test it.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, Python 3.6.5.

Introduction

These days many available different tools for Data Mining enable you to develop predictive models and analyze the data you have with unprecedented ease. InterSystems IRIS Data Platform provide a stable foundation for your big data and fast data applications, providing interoperability with modern DataMining tools.

Hi dev community,

I am currently working on an interface that needs to communicate to a SOAP/ITK endpoint.

I am using the EnsLib.ITK.AdapterKit.Operation.SOAPOperation to interface with an ITK
service, but it is proving to be more complex than originally expected to set up the web client
against that particular end-point since I haven't been provided with a WSDL from ITK service side as
the vendor state they are following the ITK standard and no WSDLs are needed.

Hi all.

I want to insert my dataframe into InterSystems IRIS. So, I tried to do this:

df = spark.read.load("/home/imported-openssh-key/zeppelin-0.8.0-bin-all/bin/resultData3/DF.json", format="json")
df.write.format("com.intersystems.spark").\
option("url", "IRIS://localhost:51773/DEDUPL").\
option("user", "********").option("password", "********").\
option("dbtable", "try.test1").save()

And got this error:

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL - api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format
