NAME

       RDF::iCalendar::Exporter - export RDF data to iCalendar format

SYNOPSIS

        use RDF::iCalendar;

        my $input    = "http://example.com/calendar-data.ics";
        my $exporter = RDF::iCalendar::Exporter->new;

        print $_ foreach $exporter->export_calendars($input);

DESCRIPTION

       This module reads RDF and writes iCalendar files.

       This is a subclass of RDF::vCard::Exporter, so it can also export vCards.

   Constructor
       •   "new(%options)"

           Returns a new RDF::iCalendar::Exporter object.

           There are no valid options at the moment - the hash is reserved for future use.

   Methods
       •   "export_calendars($input, %options)"

           Returns a list of iCalendars 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 "rdf_parse" method of RDF::TrineShortcuts.

           Each item in the list returned is an RDF::iCalendar::Entity, though that class
           overloads stringification, so you can just treat each item as a string mostly.

       •   "export_calendar($input, $subject, %options)"

           As per "export_calendars" but exports just a single calendar.

           The subject provided must be an RDF::Trine::Node::Blank or RDF::Trine::Node::Resource
           of type icaltzd:Vcalendar.

       •   "export_component($input, $subject, %options)"

           Exports a component from a calendar - e.g. a single VEVENT

           The subject provided must be an RDF::Trine::Node::Blank or RDF::Trine::Node::Resource
           of type icaltzd:Vevent, icaltzd:Vtodo or similar.

       •   "export_cards($input, %options)"

           See RDF::vCard::Exporter.

       •   "export_card($input, $subject, %options)"

           See RDF::vCard::Exporter.

   RDF Input
       Input is expected to use the newer of the 2005 revision of the W3C's vCard vocabulary
       <http://www.w3.org/TR/rdfcal/>. (Note that even though this was revised in 2005, the term
       URIs include "2002" in them.)

       Some extensions from the namespace <http://buzzword.org.uk/rdf/icaltzdx#> are also
       supported.

   iCalendar Output
       The output of this module aims at iCalendar (RFC 2445) compliance.  In the face of weird
       input data though, (e.g. an DTSTART property that is a URI instead of a literal) it can
       pretty easily descend into exporting junk, non-compliant iCalendars.

       The output has barely been tested in any iCalendar-supporting software, so beware.
