InterSystems Java Contest

Hey Developers,

We are super excited to invite you all to the new InterSystems online programming contest focused on Java and its derivatives! 

🏆 InterSystems Java Programming Contest 🏆

Duration: November 13 - December 3, 2023

Prize pool: $14,000

The topic

We invite you to use Java in a new programming contest! Applications that use Kotlin, Clojure and Scala are also very welcome.

Submit an open-source application that uses Java, Kotlin, Clojure or Scala with InterSystems IRIS or InterSystems IRIS for Health.

General Requirements:

  1. An application or library must be fully functional. It should not be an import or a direct interface for an already existing library in another language (except for C++, there you really need to do a lot of work to create an interface for Iris). It should not be a copy-paste of an existing application or library.
  2. Accepted applications: new to Open Exchange apps or existing ones, but with a significant improvement. Our team will review all applications before approving them for the contest.
  3. The application should work either on IRIS Community Edition or IRIS for Health Community Edition. Both could be downloaded as host (Mac, Windows) versions from Evaluation site, or can be used in a form of containers pulled from InterSystems Container Registry or Community Containers: intersystemsdc/iris-community:latest or intersystemsdc/irishealth-community:latest .  
  4. The application should be Open Source and published on GitHub. 
  5. The README file to the application should be in English, contain the installation steps, and contain either the video demo or/and a description of how the application works.
  6. Only 3 submissions from one developer are allowed.

NB. Our experts will have the final say in whether the application is approved for the contest or not based on the criteria of complexity and usefulness. Their decision is final and not subject to appeal.


1. Experts Nomination - a specially selected jury will determine winners:

🥇 1st place - $5,000

🥉 3rd place - $1,500

🏅 4th place - $750

🥈 2nd place - $750 

🥉 3rd place - $500

🏅 4th place - $300
