It looks like the use case is specifying types for dataflow operators (aka endpoints for dataflow pipes) [0] and I surmise composition should be super easy. I was surprised not to see any mention of XML or XML Schema as prior art, especially with their discussion of schema registries. Edit: Oh, the point of reference is Kafka [1]

I also thought about XML. It has the Document Object Model (DOM), the structure which describes the data.
