NAME
    Net::Flickr::RDF - a.k.a RDF::Describes::Flickr

SYNOPSIS
     use Net::Flickr::RDF;
     use Config::Simple;
     use IO::AtomicFile;

     my $cfg = Config::Simple->new("/path/to/my.cfg");
     my $rdf = Net::Flickr::RDF->new($cfg);

     my $fh  = IO::AtomicFile->open("/foo/bar.rdf","w");

     $rdf->describe_photo({photo_id => 123,
                           secret   => 567,
                           fh       => \*$fh});

DESCRIPTION
    Describe Flickr photos as RDF.

    This package inherits from *Net::Flickr::API*.

OPTIONS
    Options are passed to Net::Flickr::Backup using a Config::Simple object
    or a valid Config::Simple config file. Options are grouped by "block".

  flickr

    * api_key
        String. *required*

        A valid Flickr API key.

    * api_secret
        String. *required*

        A valid Flickr Auth API secret key.

    * auth_token
        String. *required*

        A valid Flickr Auth API token.

  rdf

    * query_geonames
        Boolean.

        If true and a photo has geodata (latitude, longitude) associated
        with it, then the geonames.org database will be queried for a
        corresponding match. Data will be added as properties of the photo's
        geo:Point description. For example :

         <geo:Point rdf:about="http://www.flickr.com/photos/35034348999@N01/272880469#location">
            <geo:long>-122.025151</geo:long>
            <flickr:accuracy>16</ymaps:flickr>
            <acl:access>visbility</acl:access>
            <geo:lat>37.417839</geo:lat>
            <acl:accessor>public</acl:accessor>
            <geoname:Feature rdf:resource="http://ws.geonames.org/rdf?geonameId=5409655"/>
         </geo:Point>

  $obj->add_namespace($prefix, $namespace)

    Add a prefix and namespace URI to the list of known namespaces.

    This method returns a string containing the prefix you should use for
    the namespace URI passed. If the prefix passed to the method is already
    reserved for another namespace the method will return the following
    string:

     "nfr_" + I<the prefix passed to the method>

  $obj->namespace_prefix($uri)

    Return the namespace prefix for *$uri*

  $obj->uri_shortform($prefix,$name)

    Returns a string in the form of *prefix*:*property*. The property is the
    value of $name. The prefix passed may or may be the same as the prefix
    returned depending on whether or not the user has defined or redefined
    their own list of namespaces.

    Unless this package is subclassed the prefix passed to the method is
    assumed to be one of prefixes in the default list of namespaces.

  $obj->api_call(\%args)

    Valid args are :

    * method
        A string containing the name of the Flickr API method you are
        calling.

    * args
        A hash ref containing the key value pairs you are passing to
        *method*

    If the method encounters any errors calling the API, receives an API
    error or can not parse the response it will log an error event, via the
    log method, and return undef.

    Otherwise it will return a *XML::LibXML::Document* object (if
    XML::LibXML is installed) or a *XML::XPath* object.

  $obj->log()

    Returns a *Log::Dispatch* object.

  $obj->serialise_triples(\@triples,\*$fh)

    Print *@triples* as RDF/XML to a filehandle (*$fh*). If no filehandle is
    defined, prints to STDOUT.

  $obj->serialize_triples(\@triples,\*$fh)

    An alias for *serialise_triples*
