Re: Welcome to the community group on Bridging GraphQL and RDF

Hi all,

My name is Blaise de Carné, i am the CTO of Conjecto
<https://www.conjecto.com>, a French company specialized in the Semantic
Web since 2012. We participated in some ESWC to present our work on the
subject.

In 2017  we won a tender from the French government to produce and publish
touristic informations in RDF in a public platform called DATAtourisme
<https://www.datatourisme.gouv.fr/>. As they asked us to provide an API to
facilitate querying RDF data for common developers, we designed a solution
based on GraphQL, with a schema generated from the DATAtourisme ontology
<https://framagit.org/datatourisme/ontology>. This library transform
GraphQL query to SPARQL, execute it the underlying RDF store and return a
JSON response.

If you want more information about this library, check this links (in
french, sorry) :

   - Documentation : https://datatourisme.frama.io/api/#/
   - Repository : https://framagit.org/datatourisme/api

Since 2017, we are excited to see all the projects that tends to solve the
same objectives, with different approaches. We are interested in
participating in this CG in order to bring our experience to discussions
that could lead to a standard way to use GraphQL over RDF data.

Best regards,
