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

rapper - Raptor RDF parsing and serializing utility SYNOPSIS
rapper [OPTIONS] INPUT-URI [INPUT-BASE-URI] EXAMPLE
rapper -o ntriples http://planetrdf.com/guide/rss.rdf rapper -i rss-tag-soup -o rss-1.0 pile-of-rss.xml http://example.org/base/ rapper --count http://example.org/index.rdf DESCRIPTION
The rapper utility allows parsing of RDF content by the Raptor RDF parser toolkit emitting the results as RDF triples in a choice of syn- taxes. The INPUT-URI can be a file name, '-' for standard input or if Raptor is built with a WWW retrieval library, a general URI. The optional INPUT-BASE-URI is used as the document parser base URI if present otherwise defaults to the INPUT-URI. A value of '-' means no base URI. OPTIONS
rapper uses the usual GNU command line syntax, with long options starting with two dashes (`-') if supported by the getopt_long function. Otherwise the short options are only available. -h, --help Show a summary of the options. -i, --input FORMAT Set the input FORMAT to one of 'rdfxml' (RDF/XML, default), 'ntriples' (N-Triples, see below), 'turtle' (Turtle, see below) or 'rss- tag-soup' (RSS Tag Soup). The RSS Tag Soup parser can turn the many XML RSS formats and Atom 0.3 into RDF triples. The list of parsers depends on how libraptor(3) was built. The list of supported parsers is given in the help summary given by -h. -I, --input-uri URI Set the input/parser base URI or use value '-' for no base. The default is the INPUT-URI argument value. -o, --output FORMAT Set the output FORMAT to 'ntriples' (N-Triples, default), 'rdfxml' (RDF/XML), 'rdfxml-abbrev' (RDF/XML with abbreviations) or 'rss-1.0' (RSS 1.0, also an RDF/XML syntax). The list of serializers depends on how libraptor(3) was built. The list of supported serializers is given in the help summary given by -h. -O, --output-uri URI Set the output/serializer base URI or use value '-' for no base. The default is the input base uri, either set by the argument INPUT-BASE-URI or via options -I, --input-uri URI -c, --count Only count the triples and produce no other output. -e, --ignore-errors Ignore errors, do not emit the messages and try to continue parsing. -f, --feature FEATURE[=VALUE] Set a parser or serializer feature FEATURE to a value, or to 1 if VALUE is omitted, Use -f help to get lists of valid parser and serializer features. If the form -f 'xmlns:prefix="uri"' is used, the prefix and namespace uri given will be set for serializing. The syntax matches XML in that either or both of prefix or uri can be omitted. -g, --guess Guess the parser to use from the source-URI rather than use the -i FORMAT. -q, --quiet No extra information messages. -r, --replace-newlines Replace newlines in multi-line literals with spaces. --show-graphs Print graph names (URIs) as they are seen in the input. This only has a meaning for parsers that support graph names such as the TRiG parser. --show-namespaces Print namespaces as they are seen in the input. -t, --trace Print URIs retrieved during parsing. Especially useful for monitoring what the guess and GRDDL parsers are doing. -w, --ignore-warnings Ignore warnings, do not emit the messages. -v, --version Print the raptor version and exit. EXAMPLES

libraptor(3),raptor-config(1) CHANGES
2.0.0 Removed -a option that did nothing. Removed -m option from rapper but it was never documented here. Removed -n option that was long hidden. Removed -s option that was equivalent to -f scanForRDF 1.4.16 Added -I/--input-uri and -O/--output-uri to set the input and output (parser and serializer) base URIs separately. 1.4.15 Added -t/--trace to do URI traces. 1.4.5 Updated to add serializer rdfxml-abbrev 1.4.3 Updated potential parser and serializers and described -f for defining namespaces. 1.3.0 Added -f for features. Added -g for guessing the parser to use. 1.1.0 Removed -a, --assume since rdf:RDF is now always optional. AUTHOR
