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.
Input is expected to use AtomOwl

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.
