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.
