Support DMN Level 3 conformance level #707

Open nikku opened 2 years ago

nikku commented 2 years ago

This is an umbrella issue to track DMN Level 3 modeling support.

What should we do?

Allow users to model advanced constructs defined in DMN Level 3 as supported by the new Camunda DMN engine (DMN Scala):

Why should we do it?

Without being able to model these constructs DMN Level 3 engine features remain a non-feature for many users.

@barmac looked into this a while ago, see: https://gist.github.com/barmac/59d934737587e0248a65b5436bcf8e3d.

We received another validation that this is worth looking into, some day.

@barmac Maybe worth summarizing your findings here.

barmac commented 1 year ago

I spiked on boxed expressions broad support, and discovered that it would require major architectural changes in order to be implemented. It is possible but would get us busy for more than a month. However, the architecture of the library could be simplified as we could use only three packages:

Thus, we'd get rid of dmn-js-shared, and merge literal expression and decision table in a single, general library.

@barmac Let's move this back to backlog? I think we want to decide when to pick it up in an orderly manner.

barmac commented 1 year ago

Yes, it's not on the roadmap at the moment.

The private repo apparently no longer exists.
