rdf2rdf

CLI tool to convert between different RDF serialization formats.

Primarly made to test and showcase the capabilites of the rdf package.

Status

Currently supported input formats: RDF/XML, N-Triples, N-Quads, Turtle.

Currently supported output formats: N-Triples, Turtle.

More formats are coming soon.

Installation

Install as you would any other Go package:

go get -u github.com/knakk/rdf2rdf

Provided that GOPATH/bin is on your PATH, you're good to go.

When the tool has proven stable and complete, I can provide binaries for the most common OS'es for download.

Usage

rdf2rdf
-------
Convert between different RDF serialization formats.

Usage:
	rdf2rdf -in=input.xml -out=output.ttl

Options:
  -h --help      Show this message.
  -in            Input file.
  -out           Output file.
  -stream=true   Streaming mode.
  -v=false       Verbose mode (shows progress indicator)

By default the converter is streaming both input and output, emitting
converted triples/quads as soon as they are available. This ensures you can
convert huge files with minimum memory footprint. However, if you have
small datasets you can choose to load all data into memory before conversion.
This makes it possible to sort the data, remove duplicate triples, and
potentially generate more compact Turtle serializations, maximizing predicate
and object lists. Do this by setting the flag stream=false.

Conversion from a quad-format to a triple-format will disregard the triple's
context (graph). Conversion from a triple-format to a quad-format is not
supported.

Input and ouput formats are determined by file extensions, according to
the following table:

  Format    | File extension
  ----------|-------------------
  N-Triples | .nt
  N-Quads   | .nq
  RDF/XML   | .rdf .rdfxml .xml
  Turtle    | .ttl
