I don't think I am going to use it as the table is way too big though.

As it appears many of the dcterms predicates remain unused. Even the
ones that do get used are used only very rarely.

Next up: Move to report, formalize.

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

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

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.

I'll only need it for a demo, probably. But it's nice to have.

Should be enough to (1) talk to the Java API and (2) provide
a JSON API for the world.

This is really just experimental. MMT should be integrated directly
w/o JSON if possible to avoid nonsensical serialization.

Honestly Play is way too much for what I need. I just need
a simple JSON endpoint.

- I'll need some REST endpoint for the data

- GrahDB uses RDF4J -> JVM language prefered

- Let's try out Play. It works w/ Scala and Java.

- code goes into /src

- prose in /doc

- /experimental is a playground
