Assumptions

For simplification, some assumptions are made so the main topic of each of the use-cases are not distracted with side details.

These would be:

• client-server communication uses JSON-LD RDF serialization using HTTP headers: Content-Type: application/ld+json for server responses Accept: application/ld+json client requests
• JSON-LD context is described later on in this document and is referenced in further example payloads with this property:

  {
      "@context": "/api/context.jsonld"
      // further example payload goes here
  }

• to simplify, the host was dropped from all URLs. We can assume an example like http://example.com/.
