NAME

       XML::Atom::FromOWL - export RDF data to Atom

SYNOPSIS

        use LWP::UserAgent;
        use XML::Atom::OWL;
        use XML::Atom::FromOWL;

        my $ua       = LWP::UserAgent->new;
        my $r        = $ua->get('http://intertwingly.net/blog/index.atom');
        my $atomowl  = XML::Atom::OWL->new($r->decoded_content, $r->base);
        my $model    = $atomowl->consume->graph;  ## an RDF::Trine::Model

        my $exporter = XML::Atom::FromOWL->new;
        print $_->as_xml
               foreach $exporter->export_feeds($model);

DESCRIPTION

       This module reads RDF and writes Atom feeds. It does the reverse of XML::Atom::OWL.

   Constructor
       •   "new(%options)"

           Returns a new XML::Atom::FromOWL object.

           There are no valid options at the moment - the hash is reserved for future use.

   Methods
       •   "export_feeds($input, %options)"

           Returns a list of feeds found in the input, in no particular order.

           The  input  may  be  a  URI, file name, RDF::Trine::Model or anything else that can be handled by the
           "parse" function of RDF::TrineX::Functions.

           Each item in the list returned is an XML::Atom::Feed.

       •   "export_feed($input, $subject, %options)"

           As per "export_feeds" but exports just a single feed.

           The subject provided  must  be  an  RDF::Trine::Node::Blank  or  RDF::Trine::Node::Resource  of  type
           awol:Feed.

       •   "export_entries($input, %options)"

           Returns a list of entries found in the input, in no particular order.

           The  input  may  be  a  URI, file name, RDF::Trine::Model or anything else that can be handled by the
           "parse" function of RDF::TrineX::Functions.

           Each item in the list returned is an XML::Atom::Entry.

       •   "export_entry($input, $subject, %options)"

           As per "export_entry" but exports just a single entry.

           The subject provided  must  be  an  RDF::Trine::Node::Blank  or  RDF::Trine::Node::Resource  of  type
           awol:Entry.

   RDF Input
       Input is expected to use AtomOwl <http://bblfish.net/work/atom-owl/2006-06-06/#>.

   Feed Output
       This  module  doesn't attempt to enforce many of OWL's semantic constraints (e.g. it doesn't enforce that
       an entry has only one title). It relies on XML::Atom::Feed and XML::Atom::Entry for that sort  of  thing,
       but if your input is sensible that shouldn't be a problem.
