Rasqal RDF Query Library - Rasqal RDF parser utility


NAME

roqet − Rasqal RDF parser utility

SYNOPSIS

roqet [OPTIONS] <query-URI> [base-URI]

EXAMPLE

roqet example.rdql
roqet -q x.rdql http://example.org/base/


DESCRIPTION

The roqet utility allows the querying of RDF content using the Rasqal RDF query library, emitting the results as variable bindings (at present). The query-URI can only be a file name at present; a future version may allow URIs. The optional base-URI is used as the document URI if present.

OPTIONS

roqet 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 LANGUAGE

Set the input query LANGUAGE to one of the allowed languages, presently just ’rdql’ (RDQL, default). The list of supported languages is given in the help summary given by −h.

−c, −−count

Only count the triples and produce no other output.

−q, −−quiet

No extra information messages.

−v, −−version

Print the rasqal library version and exit.
