Re: Semantic Web + GraphQL

Hi All,

Thank you so much, everybody, for your replies. I was surprised by the
great responses and projects that you are doing or mentioned. I realized
that most of the researches are about the use of the GraphQL to query
Linked Data. I'm thinking of some way to describe GraphQL components using
Semantic Web Technologies (OWL and RDF). Maybe, with this approach, I can
compose GraphQL Web Services and automatically discover that services. What
do you think about that?

Thanks!

Cheers,
Otávio.
