This is a very in-depth resource that covers nearly every aspect of SPARQL (both 1.0 and 1.1). Includes example queries (over many datasets), links to endpoints (ARQ, OpenLink's Virtuoso, Redland's Rasqal), and expected results. NOTE: The number of competencies tagged to this resource represent only a small portion its total coverage – it was necessary to omit many of the more commonly tagged competencies to save space.
