DESCRIPTION
       The  Rasqal  library  provides a high-level interface to RDF query parsing, query construction, query execution over an RDF graph and query
       results manipulation and formatting.  The library provides APIs to each of the steps in the process and provides support for handling  mul-
       tiple  query  language  syntaxes.  At present Rasqal supports most of the W3C SPARQL 1.0 Query language, some of SPARQL 1.1 draft and fully
       supports RDQL.

       Rasqal uses the libraptor(3) library for providing URI handling, WWW content retrieval and other support functions.
