Custom SERVICE HTTP requests

2017-01-01 Thread Martynas Jusevičius
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.

Just a bit more on how SERVICE-specific HTTP action is managed: https://jena.apache.org/documentation/query/service.html#configuration-from-jena-version-311 The code is here: https://github.com/apache/jena/blob/master/jena-arq/src/main/java/org/apache/jena/sparql/engine/http/QueryEngineHTTP.java
