This module reads \s-1RDF\s0 and writes Atom feeds. It does the reverse of XML::Atom::OWL.

Constructor

• \*(C`new(%options)\*(C' Returns a new XML::Atom::FromOWL object. There are no valid options at the moment - the hash is reserved for future use.

Methods

• \*(C`export_feeds($input, %options)\*(C' Returns a list of feeds found in the input, in no particular order. The input may be a \s-1URI\s0, file name, RDF::Trine::Model or anything else that can be handled by the \*(C`parse\*(C' function of RDF::TrineX::Functions. Each item in the list returned is an XML::Atom::Feed.

• \*(C`export_feed($input, $subject, %options)\*(C' As per \*(C`export_feeds\*(C' 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.

• \*(C`export_entries($input, %options)\*(C' Returns a list of entries found in the input, in no particular order. The input may be a \s-1URI\s0, file name, RDF::Trine::Model or anything else that can be handled by the \*(C`parse\*(C' function of RDF::TrineX::Functions. Each item in the list returned is an XML::Atom::Entry.

• \*(C`export_entry($input, $subject, %options)\*(C' As per \*(C`export_entry\*(C' 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.

\s-1RDF\s0 Input

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

Feed Output

This module doesn't attempt to enforce many of \s-1OWL\s0'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.

XML::Atom::OWL, HTML::Microformats, RDF::TrineX::Functions, XML::Atom::Feed, XML::Atom::Entry.
