TriG is not implemented yet for Logical Targets, could be a good feature :) If you want to dig into this yourself, feel free to make patches and send a pull request. Thanks!

[DylanVanAssche]

On the development branch, I added support for TriG in Logical Targets. Let me know if this works for you :)
