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.
