Module: Sinatra::SPARQL

Defined in:
lib/sinatra/sparql.rb

Overview

The Sinatra::SPARQL module adds Rack::SPARQL middleware support for responding to SPARQL requests. It is the responsibility of the application to manage the SPARQL endpoint and perform the query. The query results are then sent as the response body. Rack::SPARQL middleware uses content negotiation to format the results appropriately.

To override negotiation on Content-Type, set :format in sparql_options to a RDF Format class, or symbol identifying a format.
