More and more customer that want to model and execute complex decisions request additional DMN 1.3 features, such as Boxed Expressions, Contexts, Literal Expressions, and Business Knowledge Models.

There is an existing Scala Implementation that covers the above features, https://camunda.com/blog/2018/11/dmn-scala-extension/ - written by a Camundo.

To identify if this is a valid alternative to the DMN engine we currently have, we want to run a spike on the DMN scala implementation in order to identify:

• Coverage of DMN standard by the implementation
• Code quality and scope of implementing a DMN engine similar to the scala implementation into the Platform
• Remaining features to provide full DMN 1.3 coverage
