# XML::Atom::FromOWL(3pm)

export RDF data to Atom

## 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.
