Redland librdf implements each of the RDF\n      concepts in its own class via an object based API, reflected\n      into the language APIs, currently C#, Java, Perl, PHP, Python,\n      Ruby and Tcl.  Several classes providing functionality such as\n      for parsers, storage are built as modules that can be loaded at\n      compile or run-time as required.\n    "@en
