hyperobject

A simple object model for working with Linked Data.

This JSON-LD:

{
  "@context": {
    "prop": "http://dbpedia.org/property/",
    "ontology": "http://dbpedia.org/ontology/"
  },
  "@id": "http://dbpedia.org/resource/Spike_Siegal",
  "@type": "ontology:ComicsCharacter",
  "prop:name": "Spike Spiegal",
  "prop:series": "Cowboy Bebop"
}

Becomes this hyperobject:

{ id: [Getter/Setter],
  type: [Getter/Setter],
  name: [Getter/Setter],
  series: [Getter/Setter] }

Hyperobjects can be nested:

var post = new HyperObject({
  "@context": {
    "book": "http://schema.org/Book"
  }
});

var user = new HyperObject({
  "@id": "http://dbpedia.org/resource/Niel_Stephensen"
});

post.set('book:author', user);

post.author.id === user.id; // => true
post.get('author.id') === user.get('id'); // => true

Hyperobjects can be used in functional style:

var user = HyperObject(jsonld);

user.set({
  firstName: "Spike"
});

user.get('firstName');

Hyperobjects can be serialized back to JSON-LD:

JSON.stringify(user);

Installation

npm install hyperobject
