Linked Data Content Negotiation for Sinatra Applications
This is a Sinatra extension that provides Linked Data content negotiation for Sinatra applications.
This version is based on [rack-linkeddata][] without the hard dependency on the [linkeddata][] gem, to allow applications to better manage their dependencies
Features
-
Implements HTTP content negotiation for RDF content types using the
[Rack::RDF][Rack::RDF]
middleware. -
Supports all RDF.rb -compatible serialization formats.
-
Supports both classic and modular Sinatra applications.
Examples
Adding Linked Data content negotiation to a classic Sinatra application
#!/usr/bin/env ruby -rubygems
require 'sinatra'
require 'sinatra/rdf'
get '/hello' do
RDF::Graph.new do |graph|
graph << [RDF::Node.new, RDF::DC.title, "Hello, world!"]
end
end
Adding Linked Data content negotiation to a modular Sinatra application
#!/usr/bin/env ruby -rubygems
require 'sinatra/base'
require 'sinatra/rdf'
module My
class Application < Sinatra::Base
register Sinatra::RDF
get '/hello' do
RDF::Graph.new do |graph|
graph << [RDF::Node.new, RDF::DC.title, "Hello, world!"]
end
end
end
end
My::Application.run! :host => '127.0.0.1', :port => 4567
Adding Linked Data content negotiation to a Rackup application
#!/usr/bin/env rackup
require 'sinatra/base'
require 'sinatra/rdf'
module My
class Application < Sinatra::Base
register Sinatra::RDF
get '/hello' do
RDF::Graph.new do |graph|
graph << [RDF::Node.new, RDF::DC.title, "Hello, world!"]
end
end
end
end
run My::Application
Testing Linked Data content negotiation using rackup
and curl
$ rackup doc/examples/config.ru
$ curl -iH "Accept: application/n-triples" http://localhost:9292/hello
$ curl -iH "Accept: application/turtle" http://localhost:9292/hello
$ curl -iH "Accept: application/rdf+xml" http://localhost:9292/hello
$ curl -iH "Accept: application/json" http://localhost:9292/hello
$ curl -iH "Accept: application/trix" http://localhost:9292/hello
$ curl -iH "Accept: */*" http://localhost:9292/hello
Description
Sinatra::RDF
is a thin Sinatra-specific wrapper around the [Rack::RDF][Rack::RDF]
middleware, which implements Linked Data content negotiation for Rack applications.
At the moment the Sinatra extension simply corresponds to doing the following manually in a Sinatra application:
require 'rack/rdf'
module My
class Application < Sinatra::Base
use Rack::RDF::ContentNegotiation
helpers Sinatra::RDF::Helpers
include ::RDF
end
end
See the Rack::RDF
documentation for more information on the operation and details of the content negotiation.
