SYNOPSIS
Redland RDF Libraries and utilities
DESCRIPTION
Redland is a set of libraries for RDF (Resource Description Framework) processing. It provides parsing, storage, querying (SPARQL), and serialization of RDF data.
EXAMPLES
$ # Parse RDF/XML to N-Triples
rapper -i rdfxml -o ntriples data.rdf
# Validate RDF
rapper -c data.rdf
# SPARQL query
roqet -i sparql "SELECT * WHERE { ?s ?p ?o } LIMIT 10" data.rdf
# Convert formats
rapper -i turtle -o rdfxml data.ttl > data.rdf
# Create and query store
rdfproc mystore parse data.rdf
rdfproc mystore query sparql - "SELECT * WHERE { ?s ?p ?o }"
rapper -i rdfxml -o ntriples data.rdf
# Validate RDF
rapper -c data.rdf
# SPARQL query
roqet -i sparql "SELECT * WHERE { ?s ?p ?o } LIMIT 10" data.rdf
# Convert formats
rapper -i turtle -o rdfxml data.ttl > data.rdf
# Create and query store
rdfproc mystore parse data.rdf
rdfproc mystore query sparql - "SELECT * WHERE { ?s ?p ?o }"
