Hey Ruben,

Thank you for the feedback! Yes, I totally agree. Adding TypeScript
definitions is a top priority for the the next or following minor release.
Perhaps I should document planned features in the README but I will open an
issue for now.
Some progress has already been made in development, e.g., the Data Factory
definitions currently exist offline and extend the interface in
@types/rdf-js, but has not been tested.

Cheers,
 - Blake
