NAME ^

OpenGuides::RDF - An OpenGuides plugin to output RDF/XML.

DESCRIPTION ^

Does all the RDF stuff for OpenGuides. Distributed and installed as part of the OpenGuides project, not intended for independent installation. This documentation is probably only useful to OpenGuides developers.

SYNOPSIS ^

    use Wiki::Toolkit;
    use OpenGuides::Config;
    use OpenGuides::RDF;

    my $wiki = Wiki::Toolkit->new( ... );
    my $config = OpenGuides::Config->new( file => "wiki.conf" );
    my $rdf_writer = OpenGuides::RDF->new( wiki   => $wiki,
                                         config => $config );

    # RDF version of a node.
    print "Content-Type: application/rdf+xml\n\n";
    print $rdf_writer->emit_rdfxml( node => "Masala Zone, N1 0NU" );

METHODS ^

new
    my $rdf_writer = OpenGuides::RDF->new( wiki   => $wiki,
                                           config => $config );

wiki must be a Wiki::Toolkit object and config must be an OpenGuides::Config object. Both arguments mandatory.

emit_rdfxml
    $wiki->write_node( "Masala Zone, N1 0NU",
                     "Quick and tasty Indian food",
                     $checksum,
                     { comment  => "New page",
                       username => "Kake",
                       locale   => "Islington" }
    );

    print "Content-Type: application/rdf+xml\n\n";
    print $rdf_writer->emit_rdfxml( node => "Masala Zone, N1 0NU" );

Note: Some of the fields emitted by the RDF/XML generator are taken from the node metadata. The form of this metadata is not mandated by Wiki::Toolkit. Your wiki application should make sure to store some or all of the following metadata when calling write_node:

postcode - The postcode or zip code of the place discussed by the node. Defaults to the empty string.
city - The name of the city that the node is in. If not supplied, then the value of default_city in the config object supplied to new, if available, otherwise the empty string.
country - The name of the country that the node is in. If not supplied, then the value of default_country in the config object supplied to new will be used, if available, otherwise the empty string.
username - An identifier for the person who made the latest edit to the node. This person will be listed as a contributor (Dublin Core). Defaults to empty string.
locale - The value of this can be a scalar or an arrayref, since some places have a plausible claim to being in more than one locale. Each of these is put in as a Neighbourhood attribute.
phone - Only one number supported at the moment. No validation.
website - No validation.
opening_hours_text - A freeform text field.
