.SH "NAME"
RDF::iCalendar::Exporter \- export RDF data to iCalendar format
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& use RDF::iCalendar;
\& 
\& my $input    = "http://example.com/calendar\-data.ics";
\& my $exporter = RDF::iCalendar::Exporter\->new;
\& 
\& print $_ foreach $exporter\->export_calendars($input);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module reads \s-1RDF\s0 and writes iCalendar files.
.PP
This is a subclass of RDF::vCard::Exporter, so it can also export vCards.
.SS "Constructor"
.IX Subsection "Constructor"
.IP "\(bu" 4
\&\f(CW\*(C`new(%options)\*(C'\fR
.Sp
Returns a new RDF::iCalendar::Exporter 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_calendars($input, %options)\*(C'\fR
.Sp
Returns a list of iCalendars 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`rdf_parse\*(C'\fR method of RDF::TrineShortcuts.
.Sp
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.
.IP "\(bu" 4
\&\f(CW\*(C`export_calendar($input, $subject, %options)\*(C'\fR
.Sp
As per \f(CW\*(C`export_calendars\*(C'\fR but exports just a single calendar.
.Sp
The subject provided must be an RDF::Trine::Node::Blank or
RDF::Trine::Node::Resource of type icaltzd:Vcalendar.
.IP "\(bu" 4
\&\f(CW\*(C`export_component($input, $subject, %options)\*(C'\fR
.Sp
Exports a component from a calendar \- e.g. a single \s-1VEVENT\s0
.Sp
The subject provided must be an RDF::Trine::Node::Blank or
RDF::Trine::Node::Resource of type icaltzd:Vevent, icaltzd:Vtodo
or similar.
.IP "\(bu" 4
\&\f(CW\*(C`export_cards($input, %options)\*(C'\fR
.Sp
See RDF::vCard::Exporter.
.IP "\(bu" 4
\&\f(CW\*(C`export_card($input, $subject, %options)\*(C'\fR
.Sp
See RDF::vCard::Exporter.
.SS "\s-1RDF\s0 Input"
.IX Subsection "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 \*(L"2002\*(R" in
them.)
.PP
Some extensions from the namespace <http://buzzword.org.uk/rdf/icaltzdx#>
are also supported.
.SS "iCalendar Output"
.IX Subsection "iCalendar Output"
The output of this module aims at iCalendar (\s-1RFC 2445\s0) compliance.
In the face of weird input data though, (e.g. an \s-1DTSTART\s0 property that is a
\&\s-1URI\s0 instead of a literal) it can pretty easily descend into exporting
junk, non-compliant iCalendars.
.PP
The output has barely been tested in any iCalendar-supporting software,
so beware.
