Python BPL in preview

BPL from 10,000 feet

BPL stands for Business Process Language.
This is an XML format for describing complex information orchestration interactions between systems.
InterSystems Integration engine has for two decades, provided a visual designer to build, configure, and maintain, BPL using a graphical interface.
Think of it like drawing a process flow diagram that can be compiled and deployed.

Considering new business interest in applying Generative-AI to local commercially sensitive private data and information, without exposure to public clouds. Like a match needs the energy of striking to ignite, the Tech lead new "activation energy" challenge is to reveal how investing in GPU hardware could support novel competitive capabilities. The capability can reveal the use-cases that provide new value and savings.

Sharpening this axe begins with a functional protocol for running LLMs on a local laptop.

In response to a community question asking to view Request and Response message types in Production settings..

A community helper class was implemented should people need this. ( alwo.EnsHelper.HostRequestResponseInfo )


zpm install alwo-enshelper

The code may serve as an example, to project bespoke configuration into Production settings.

Am just plain curious about how people may be approaching this area.

The Question

The %SYSTEM.License API wraps an IRIS key that is specific to a range of InterSystems products with

  • Platform features
  • Platform behaviors
  • Expiry date
  • Capacity / Usage limits

If a company is implementing deployed products that:

  • run on top of IRIS
  • optionally support other vendor IRIS products

For example:

0 197

Excuse if this is obvious to Python programmers but for those crossing over from ObjectScript this may be a useful tip.

The scenario is developing some Embedded python commands.

Testing out functionality is being confirmed via the shell:

Python 3.9.5 (default, Mar 14 2023, 06:58:44) [MSC v.1927 64 bit (AMD64)] on win32
Type quit() or Ctrl-D to exit this shell.

When Python evaluates an expression in the shell, it prints the result of the expression to the terminal.

An interim idea to bring more dark to the docs with different font.


  • In Firefox web browser address bar navigate to: "about:support"
  • Look for label "Profile Folder", and click on the corresponding "Open Folder" button.
  • Drill-down / Open sub-folder called Chrome.
  • Create file here called: userContent.css

Content of file:

Interview Questions

There is documentation. A recruitment consultant wants to quickly challenge candidates with some relevant technical questions to a role.

Can they automate making a list of questions and answers from the available documentation?

Interview Answers and Learning

One of the most effective ways to cement new facts into accessible long term memory is with phased recall.

LangChain fixed the SQL for me

This article is a simple quick starter (what I did was) with SqlDatabaseChain.

Hope this ignites some interest.

Many thanks to:

sqlalchemy-iris author @Dmitry Maslennikov

Your project made this possible today.

The article script uses openai API so caution not to share table information and records externally, that you didn't intend to.

A local model could be plugged in , instead if needed.

Written in reply to community post for can Python create HL7 Message dynamically.

Pre-requisites and setup

Use an integration enabled namespace.
Note: USER namespace is not enabled for interoperability by default.
If following suggest create a new interoperatibility namespace to explore functionality.

# Switch to
ZN "[Interoperability Namespace Name]"

# Launch interactive Python shell:
Do $SYSTEM.Python.Shell()

Multidimensional properties can be found on certain classes.

These operate as a collection of values much like a Python dictionary.

Examples of properties that might be encountered:

Class Property Description
%Net.HttpRequest Params Name value pair of form parameters
%Net.HttpResponse Headers

HTTP Headers returned with web content returned:

Tuples ahead


Cross-Skilling from IRIS objectScript to Python it becomes clear there are some fascinating differences in syntax.

One of these areas was how Python returns Tuples from a method with automatic unpacking.

Effectively this presents as a method that returns multiple values. What an awesome invention :)

out1, out2 = some_function(in1, in2)

ObjectScript has an alternative approach with ByRef and Output parameters.

Do ##class(some_class).SomeMethod(.inAndOut1, in2, .out2)

Some Usage cases

1. A deployment may consist of two high availability instances and two disaster recovery instances in a different data center.

The corresponding UAT environment could replicate this giving a total of 8 instances. How do you confirm CPF and Scheduled task alignment across ALL instances.
