FHIR Bulk Data and ndjson

Hi all,

I am testing asynchronous Bulk Data retrieve with a large EHR vendor. When I retrieve the bulk data, they are returning ndjson (CONTENT-TYPE of "application/fhir+ndjson; charset=utf-8"). If I attempt to process that content using JSON functions - I get

ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

For example, the following generates the error

s objArray={}.%FromJSON(quickStreamOut)

The error makes sense in that ndjson is not a valid json format (I assume at least).

For some years I missed being able to offer, to everybody interested in ObjectScript, a tutorial more or less complete, to start with ObjectScript. Something that could help more and make things easier to those new developers that come to our technology... something intermediate, halfway between the common "Hello World!", that doesn't really get you further, and the "Advanced Training", that is unaffordable because of lack of time,etc.

If there were something truly helpful not only as an introduction to the ecosystem, but as a starting point, as a boost, to really start to walk into ObjectScript and move forward by yourself... wouldn't that be awesome?

Does anyone know of a relatively quick and straightforward way of converting code written in the old dot scoping syntax with argumentless do (see here for reference: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_cdo_legacy) to the modern parentheses scoping syntax? It's not too bad to do it by hand, but it's also easy to make a mistake and leave a "quit" in an if statement by accident for example.

E.g.

Hi! For the Opendataset contest I've build a docker container app stack that use InterSystems IRIS & Openflights Dataset in a container and second container with Apache Zeppelin. You can found details here: https://github.com/andreas5588/openflights_demo

With that you can query the Opendflights Dataset from Apache Zepplin with zero configuration. The containers are on hub.docker so you can use it very easily.

Hi everyone,

I want to talk about our project and use the dataset theme for this contest.

Our intention never was to be a data curator, especially because sometimes my precious data means a lot for me, but not for the rest of the world.

My Precious

We want to go a step further and empower the user to find the perfect dataset for their needs.

Our project is a bridge between the data science community and the developer's community using InterSystems IRIS to achieve this mission.

Your own webserver logfile analyser

Previously I had published The Article about the dataset from a real webserver, which can demonstrate how can activity and load of the Apache webserver depends on day of week, search engines indexing and some network noise.

Now I want to describe one useful function for most of webmasters and system administrators who are interested in obtaining of exactly information about visitors, hardware usage, and also about errors that gaing to their clients.

Here it is

Real Webserver Logs Dataset

I'm happy to share with the community a web server log dataset from our longtime customer, an operating company.

Their webserver operates on Apache webserver and contains data which can be useful to analyse a load and search engines activity.

After installing the project, you will get the data for a few months that can show a typical load and activity of clients, robots and also you can see how it depends on day of week, holidays and time of a day.

The Cube is also included in package.

II try to explore the new SQL LOAD DATA feature in SQL comparing it to SQL INSERT

I'm stuck at this point: INSERT INTO <table> (columns...) VALUES (.....)
allows having not just simple column references but also ALL Standard SQL FUNCTIONS (at least)
example:

INSERT INTO Test (ShortName,DOB) VALUES (SUBSTRING(Name,1,4),TO_DATE(displayDate,'MM-DD_YYY'))

This works perfectly.
BUT the same VALUE clause applied to LOAD DATA fails in various ways:

Predict Maternal Health Risks

Hi community,

Prediction is a critical to the Maternal healthcare. The Health Dataset Application (https://openexchange.intersystems.com/package/Health-Dataset) has 10 real health datasets to predict the most important diseases and health problems, including Maternal Risk.

This article detail the steps to predict Maternal Risk using the InterSystems IRIS IntegratedML. This is a technology of InterSystems to do predictions using SQL Commnands! Great!

SQL LOAD DATA date values

I have csv date file with date values like this "4/10/2021" for April 10, 2021. I defined a table with this property: Property TranDate As %Library.Date.

I capture error

[SQLCODE: <-104>:<Field validation failed in INSERT, or value failed to convert in DisplayToLogical or OdbcToLogical>] [Location: <ServerLoop>] [%msg: <Field 'dc_data_finance.transact.TranDate' (value '4/10/2021') failed validation Field ...

I do not really want to change TranDate to %String. How can I import "4/10/2021" into %Date property?

Hi folks!

Sometimes we need the docker image of the InterSystems IRIS solution we build to be published on some docker registry. The cases could be:

  1. Deploy it then in Kubernetes cluster
  2. Let your pal run the image of your public repo without building it locally.

You can push the image to Docker Hub Registry or Github Registry.

In this very short article, I provide a way how to do it automatically on every push to your GitHub repository.

Hello developers, I'm a newbie to Intersystems technologies and I started to work with Caché and Ensemble, and to be more specific I'm working with systems integration. In a scenario where I need to develop new software from scratch, would it be better to develop this new software using REST APIs? Does anyone have any recommendations about courses?
