NAME

       trapper - command-line RDF parsing and serialising tool

SYNOPSIS

	 trapper [options] INPUT-URI [INPUT-BASE-URI]

	 Options:
	   --input F, -i F	 Set the input format to F
	   --input-uri U, -I U	 Alternative to INPUT-BASE-URI
	   --output F, -o F	 Set the output format to F
	   --count, -c		 Count triples only
	   --quiet, -q		 No extra information messages
	   --help, -h		 Show this help
	   --version, -v	 Show module versions

	 Input formats: rdfxml, n3, turtle, rdfa, nquads, trig, rdfjson, atom, xrd.

	 Output formats: rdfxml, n3, turtle, ntriples, rdfa, nquads, rdfjson, canonical.

OPTIONS

       --input, -i
	   Specify the input format. The synopsis of this manual page shows a list of input formats. Using media types should work too. In
	   summary, it accepts any type that the "rdf_parse" function from RDF::TrineShortcuts accepts.

	   If an input type is not specified, trapper will try to guess the input type (and will almost always get it right).

       --input-uri, -I, INPUT-BASE-URI
	   Any of these three methods can be used to specify a base URI for the parser to resolve relative URI references.

       --output, -o
	   Specifies the output format. The synopsis of this manual page shows a list of input formats. Using media types should work too. In
	   summary, it accepts any type that the "rdf_string" function from RDF::TrineShortcuts accepts.

	   If an input type is not specified, 'ntriples' is assumed.

       --count, -c
	   Suppresses the output of the data, and just shows a count of triples instead.

       --quiet, -q
	   Hides useless debugging messages.

       --help, -h
	   Shows a short help message.

       --version, -v
	   Shows the version of various Perl modules used by trapper. trapper itself doesn't have a version number, but is distributed along with
	   RDF::TrineShortcuts, so could be considered to have the same version number as that.

SHEBANG!!
       trapper can be used as a shebang line of a Turtle or N-Triples file. e.g.:

	 #!/usr/local/bin/trapper OPTS: -i turtle -o rdfxml

	 @prefix foaf: <http://xmlns.com/foaf/0.1/> .

	 [] a foaf:Person ;
	    foaf:name "Toby Inkster" .

       Note that you need the "OPTS:" bit to pass command-line options.  This is a workaround for a limitation in Linux's shebang handling.

NOTE

       When possible, trapper attempts to use the same command-line options as the 'rapper' tool that is distributed with libraptor.  However,
       full compatibility with rapper is not a goal, and is certainly not guaranteed.

       A trapper is a person who catches animals, usually for fur.

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
       o   "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
       o   "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.

       o   "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.

       o   "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.

       o   "export_cards($input, %options)"

	   See RDF::vCard::Exporter.

       o   "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.
