I’ve read your abstract and it looks very interesting! I’ll be diving into the rest as I find time over the next few weeks thanks for sharing! And well done on this piece of work!

It was interesting to me that you mentioned “functional programming as a model for data-oriented workflow languages”. I find it interesting because we are building Lowdefy [0] with which you can express feature rich apps in yaml / json, and have been considering how to implement DAG type stuff in future versions.

We’ve taken a lot of inspiration from Mongodb aggression query language and as a result built a json / yaml parser which evaluates functions (operators) to implement logic throughout the app. This proved to be extremely flexible, easy to use for data manipulation, and surprisingly performant as we can actually evaluate the expressions during the render loop.

Going to read more parts of your thesis.
