.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module reads \s-1RDF\s0 and writes Atom feeds. It does the reverse
of XML::Atom::OWL.
.SS "Constructor"
.IX Subsection "Constructor"
.IP "\(bu" 4
\&\f(CW\*(C`new(%options)\*(C'\fR
.Sp
Returns a new XML::Atom::FromOWL object.
.Sp
There are no valid options at the moment \- the hash is reserved
for future use.
.SS "Methods"
.IX Subsection "Methods"
.IP "\(bu" 4
\&\f(CW\*(C`export_feeds($input, %options)\*(C'\fR
.Sp
Returns a list of feeds found in the input, in no particular order.
.Sp
The input may be a \s-1URI,\s0 file name, RDF::Trine::Model or anything else
that can be handled by the \f(CW\*(C`parse\*(C'\fR function of RDF::TrineX::Functions.
.Sp
Each item in the list returned is an XML::Atom::Feed.
.IP "\(bu" 4
\&\f(CW\*(C`export_feed($input, $subject, %options)\*(C'\fR
.Sp
As per \f(CW\*(C`export_feeds\*(C'\fR but exports just a single feed.
.Sp
The subject provided must be an RDF::Trine::Node::Blank or
RDF::Trine::Node::Resource of type awol:Feed.
.IP "\(bu" 4
\&\f(CW\*(C`export_entries($input, %options)\*(C'\fR
.Sp
Returns a list of entries found in the input, in no particular order.
.Sp
The input may be a \s-1URI,\s0 file name, RDF::Trine::Model or anything else
that can be handled by the \f(CW\*(C`parse\*(C'\fR function of RDF::TrineX::Functions.
.Sp
Each item in the list returned is an XML::Atom::Entry.
.IP "\(bu" 4
\&\f(CW\*(C`export_entry($input, $subject, %options)\*(C'\fR
.Sp
As per \f(CW\*(C`export_entry\*(C'\fR but exports just a single entry.
.Sp
The subject provided must be an RDF::Trine::Node::Blank or
RDF::Trine::Node::Resource of type awol:Entry.
.SS "\s-1RDF\s0 Input"
.IX Subsection "RDF Input"
Input is expected to use AtomOwl
<http://bblfish.net/work/atom\-owl/2006\-06\-06/#>.
.SS "Feed Output"
.IX Subsection "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.
