That particular code has been retired because after a quite a bit of trying things that weren’t quite right we understood the problem and found a better way to do it. I’m doing the next round of related work (logically modeling XSLT schemas and associated messages in OWL) in Java because there is already a library that almost does was I want.

I am still using this library that I wrote

https://paulhoule.github.io/gastrodon/

to visualize RDF data so even if I make my RDF model in Java I am likely to load it up in Python to explore it. I don’t know if they are using PyPy but there is at least one big bank that has people using Gastrodon for the same purpose.
