Rasqal RDF query library Rasqal is a C library providing support for querying the Resource Description Framework (RDF) including parsing query syntaxes, constructing the queries, executing them and returning result bindings. It currently supports the SPARQL RDF Query languages and RDF Data Query Language (RDQL). Rasqal is designed for performance, flexibility and embedding (no memory leaks) and to track ongoing RDF query language work.
