Rasqal handles Resource Description Framework (RDF) query syntaxes, query
construction and query execution returning result bindings. The supported
query languages are RDQL and SPARQL. Rasqal was designed to work closely
with the Redland RDF library but is entirely separate. It is intended to be
a portable library working across many POSIX systems (Unix, GNU/Linux,
BSDs, OSX, cygwin) win32 and others.
