Hey, happy 2017 :)
I am wondering if there is a way to "intercept" the HTTP request that is being generated by the SERVICE clause? As you might know, some triplestores (RDF4J, Dydra) provide an extension of the SPARQL protocol that allows sending query bindings separately from the query string. (Too bad it's not standardized and I'm not even able to find a good reference right now, but that is another topic). We have implemented it with a custom SPARQL client, but how can we plug it into the federated query execution? Thanks. Martynas
