Open Source REST API for SpaceX data

Just want to point out that this is not an official API made by SpaceX, but by people hanging around https://www.reddit.com/r/spacex.

Is there a schema definition available for this API or you are supposed to figure it out by looking at actual replies and hope it doesn't change?

Is there even an equvalent of XSD but for JSON?

I wonder if this kind of data would be better structured in a semantic web way, with a well-defined schema and RDF rather than a siloed JSON REST thing.

What could that be used for, apart from news reporting automation?

.Net, PowerShell

We are doomed.
