Did anyone tried a JSON-LD Processor with a real data source, eg. DBpedia? this is what i got when using the ruby gem: https://github.com/gkellogg/json-ld could not achieve that with javascript (https://github.com/digitalbazaar/jsonld.js) yet.. is there any best practice to deal with a real data source in combination with JSON-LD?

jsonld.rb

require 'rubygems'
require 'json/ld'
require 'net/http'

context = {
  "foaf" => "http://xmlns.com/foaf/0.1/",
  "dbo" => "http://dbpedia.org/ontology/",
  "xsd" => "http://www.w3.org/2001/XMLSchema#",

  "name" => {
    "@id" => "foaf:name",
    "@type" => ""
  },
  "born"=> {
    "@type" => "xsd:date",
    "@id"=> "dbo:birthDate"
  },
  "thumb" => "dbo:thumbnail",
  "homepage" => "foaf:homepage"
}

id = "http://dbpedia.org/resource/Jim_Carrey"
response = Net::HTTP.get_response("dbpedia.org","/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=DESCRIBE+%3Chttp://dbpedia.org/resource/Jim_Carrey%3E&output=application%2Fld%2Bjson")
input = JSON.parse response.body
input = input["@id"]

compact = JSON::LD::API.compact(input, context)

jim_carrey = compact["@graph"].detect do |resource|
  resource["@id"] == id
end

puts jim_carrey["name"] # {"@language"=>"en", "@value"=>"Jim Carrey"}
puts jim_carrey["born"].first # 1962-01-17
puts jim_carrey["thumb"]
puts jim_carrey["homepage"]


# getting his movies
movies = compact["@graph"].map do |resource|
  resource["@id"] if resource["dbo:starring"] == id
end

puts "---------------------------"
puts "Jim Carrey Movies:"
puts movies.compact!

Good news.. DBpedia has been fixed. So as long as you set the right Accept headers and follow the redirect you get the data directly. You can try it with curl:

curl -LH "Accept: application/ld+json" http://dbpedia.org/resource/Jim_Carrey

I'll leave the rest to @gkellogg as he's the Ruby expert.

oh ok cool! thank you, maybe i'm gonna now try something in javascript ;)
