NAME Apache::XPointer::RDQL - mod_perl handler for addressing XML fragments using the RDF Data Query Language. SYNOPSIS SetHandler perl-script PerlHandler Apache::XPointer::RDQL::RDFStore PerlSetVar XPointerSendRangeAs "application/rdf+xml" # my $ua = LWP::UserAgent->new(); my $req = HTTP::Request->new(GET => "http://example.com/foo/bar/baz.rdf"); $req->header("Range" => qq(SELECT ?title, ?link WHERE (?item, , ), (?item, , ?title), (?item, , ?link) USING rdf for , rss for )); $req->header("Accept" => qq(mulitpart/mixed)); my $res = $ua->request($req); DESCRIPTION Apache::XPointer::RDQL::RDFStore is a mod_perl handler to address XML fragments using the HTTP 1.1 *Range* and *Accept* headers and the XPath scheme, as described in the paper : *A Semantic Web Resource Protocol: XPointer and HTTP*. Additionally, the handler may also be configured to recognize a conventional CGI parameter as a valid range identifier. If no 'range' property is found, then the original document is sent unaltered. If an *Accept* header is specified with no corresponding match, then the server will return (406) HTTP_NOT_ACCEPTABLE. Successful queries will return (206) HTTP_PARTIAL_CONTENT. IMPORTANT This package is a base class and not expected to be invoked directly. Please use one of the RDQL parser-specific handlers instead.
