Onto2Nx is NOT MAINTAINED¶
This project is no longer maintained. There are a few better alternatives:
https://github.com/related-sciences/nxontology (Custom parsing of OWL into NetworkX graphs)
https://github.com/dhimmel/obonet/ (Custom parsing of OBO into NetworkX graphs)
https://github.com/althonos/pronto (General parsing of OBO + OWL)
If you want to look at the docs, though, they’re still here:
A package for parsing ontologies in the OWL and OBO format into NetworkX graphs.
