Hi Grakn.ai data model looks very much like RDF[1] with SPARQL[2] as a query language. There are quite a few data stores, owl reasoners and various libraries to work with rdf. There are haskell packages as well: rdf4h[3] for data representation, hsparql[4] to create and submit queries to sparql stores, swish[5] is a semantic web toolkit. Hope that would be helpful for you.

Graql[1] is a (and stands for) graph query language. It is unusually expressive, allowing relationships to be members of other relationships[2] -- effectively, allowing one edge to be an endpoint of another edge.
Someone named Felix posted a Haskell library for generating Graql queries[3].
Does anyone have a Haskell program that not only generates but uses such a query?
