That's SPARQL and RDF4J.

- It's mostly about file structure/organization (duh)

- It also contains slightly deeper links, e.g. about on what objects
  other things are defined.

- In the end it's all about links. There are some data properties but
  they are honestly not that interesting. They are necessary for
  lookup however.

Turns out, only maybe 1/3 of all available predicates are actually
part of the exported datasets. No surprise my queries are hitting
nothing.

I like playing w/ languages, but I am not sure at all if this is a
good idea.

First draft; will be revised.

This will be very useful for further integration w/ JVM tech.

It's a script that generates a Java/RDF4J file with constants
for the OWL ontology. This makes working with ULO convinient.

I also etst performance and it looks okay on my small laptop.

- This also works just as well as a REST endpoint.

- Most likely this is just a demo. But it works for that.
