Introducing Linked Objects

What is a Linked Object?

A linked object is is an object which you get from an URL, the URL is its id.

What are the Benefits?

It allows you to update nested objects independently of each other and reference them within multiple different objects since they are by reference.

Linked Object Notation (LION)

The Linked Objects Notation (LION) is a simple subset of JSON-LD. It aims to avoid most of the complexity, and enables getting started quickly, using a familiar notation. LION is compatible with JSON-LD and offers a full upgrade path.

A Simple Example

<script type="application/ld+json">
{
  "@id": "http://dbpedia.org/resource/John_Lennon",
  "name": "John Lennon",
  "born": "1940-10-09",
  "spouse": "http://dbpedia.org/resource/Cynthia_Lennon"
}
</script>

@id

@id is the URL of the object. It can also be written "id". The @id can be absolute or relative. @id is optional but recommended, and makes an object into an Linked Object.

@type

@type is the type of for that object. It can also be written "type". @type normally maps to a URL. Type is optional.

@context

@context is optional. It provides full compatibility with JSON-LD and and maps various items in the object to URLs in a more readable way.
