NAME

     serdi — read and write RDF syntax

SYNOPSIS

     serdi [-abefhlqv] [-c prefix] [-i syntax] [-o syntax] [-p prefix] [-r root] [-s string]
           input [base_uri]

DESCRIPTION

     serdi is a fast command-line utility for streaming and processing RDF data.  It reads an RDF
     document and writes the data to stdout, possibly transformed and/or in a different syntax.
     By default, the input syntax is guessed from the file extension, and output is written in
     NTriples or NQuads.

     serdi can be used to check for syntax errors, convert from one syntax to another, pretty-
     print documents, or transform URIs and blank node IDs.

     The options are as follows:

     -a   Write ASCII output.  If this is enabled, all non-ASCII characters will be escaped, even
          if the output syntax allows them to be written in UTF-8.

     -b   Bulk output writing.  If this is enabled, output will be written a page at a time,
          rather than a byte at a time.

     -c prefix
          Chop prefix from matching blank node IDs.  This is the inverse of -p.

     -e   Eat input one character at a time, rather than a page at a time which is the default.
          This is useful when reading from a pipe since output will be generated immediately as
          input arrives, rather than waiting until an entire page of input has arrived.  With
          this option serdi uses one page less memory, but will likely be significantly slower.

     -f   Keep full URIs in input (don't qualify with namespace prefixes or make URIs relative).

     -h   Print the command line options.

     -i syntax
          Read input as syntax.  Case is ignored, valid values are: “NQuads”, “NTriples”, “TriG”,
          “Turtle”.

     -l   Lax (non-strict) parsing.  If this is enabled, recoverable syntax errors will print a
          warning, but parsing will proceed starting at the next statement if possible.  Note
          that data may be lost when using this option.

     -o syntax
          Write output as syntax.  Case is ignored, valid values are: “NQuads”, “NTriples”,
          “TriG”, “Turtle”.

     -p prefix
          Add prefix to blank node IDs.  This can be used to avoid clashes between blank node IDs
          in input documents.

     -q   Suppress all output except data.

     -r root
          Keep relative URIs within a root URI.  This will avoid creating any relative URI
          references with leading path segments like “../” that enter a parent of root.

     -s string
          Parse string input instead of a file (terminates options).

     -v   Display version information and exit.

EXIT STATUS

     serdi exits with a status of 0, or non-zero if an error occurred.

EXAMPLES

     To pretty-print a document:

           $ serdi -o turtle file.ttl > out.ttl

     To print any errors:

           $ serdi file.ttl > /dev/null
