Re: 🚀 graphy.js - High Performance API and CLI - Major Release v4.0.0 🎉

Blake,

great work.

What would it take to add RDF/XML support? Writer would be a priority for me.

If I would attempt to write some compatible code, is this an example to follow?

One feature that graphy currently lacks however is a parser for the N3 language.
