== DESCRIPTION:
A library for working with RDF data in Ruby.
== FEATURES/PROBLEMS:
* A in-memory, pure ruby implementation of the RDF graph model.
== SYNOPSIS:
===Adding data to a graph
g = RDF::Graph::Memory.new
g.add(UriNode.new('http://paul.stadig.name/'), RDF::type, RDF::Resource)
===Registering a new namespace
RDF::Namespace.register(:dc, 'http://purl.org/dc/elements/1.1/')
# you can also create instances of Triple and add them to the graph
t = RDF::Triple.new(UriNode.new('http://paul.stadig.name/'),
DC::author,
g.new_blank_node('paul'))
g.add(t)
===Querying a graph
q = Query.new
q.select(:x, :y).where(:x, DC::author, :y)
result = g.execute(q)
result.bindings.each do |b|
puts "x = #b[:x]"
puts "y = #b[:y]"
end
== REQUIREMENTS:
* ruby >= 1.8
* rubygems >= 0.9.8
* utf8proc >= 1.0.3
* uuidtools >= 1.0.1
== INSTALL:
* sudo gem install rubyrdf
