RDF::iCalendar::Exporter(3) 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.
