trist - command-line RDF statistics SYNOPSIS
trist [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 --summary, --nosummary Show/hide summary info --vocabs, --novocabs Show/hide vocabulary info --nodes=X Show ABox node info --quiet, -q No extra information messages --help, -h Show this help --version, -v Show module versions Input formats: rdfxml, n3, turtle, rdfa, rdfjson, nquads, trig, atom, xrd. 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, trist 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. --summary, --nosummary Show (or not) a summary of the RDF data. Shown by default. Includes counts of the number of unique values in subject, predicate and object positions, along with the most popular subject, predicate and object; etc. In this summary, "Type" is defined as any node that is the object of a triple where the predicate is rdf:type; "Vocabulary" is calculated from splitting predicate URIs and type URIs into vocabulary and term using QName rules. --vocabs, --novocabs Vocabularies calculated as above. This shows all vocabularies used in the source RDF data; not just the single most popular one. --nodes=X Show the X most popular "ABox" nodes. RDF doesn't actually distinguish between so called TBox and ABox terms, but this tool treats any predicates or rdf:type objects as TBox, everything else as ABox. One-off literals are ignored. --quiet, -q Hides useless debugging messages. --help, -h Shows a short help message. --version, -v Shows the version of various Perl modules used by trist. trist 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. NOTE
Trist is a tool that generates a set of statistics about some input RDF data. Its output is in Turtle, designed to be as human-readable as possible. Trist is an archaic spelling of 'tryst' which is a secret meeting. AUTHOR

TRAPPER(1p) User Contributed Perl Documentation TRAPPER(1p) 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. AUTHOR
