roqet − Rasqal RDF parser utility |
roqet [OPTIONS] <query-URI> [base-URI] |
roqet example.rdql roqet -q x.rdql http://example.org/base/ |
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. |
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. |

−c, −−count |
Only count the triples and produce no other output. |
−q, −−quiet |
No extra information messages. |

Print the rasqal library version and exit. |
