Re: The Digest Class (Security Vocab)

To give a concrete example, 8 goes from:

Example 8

{
  "@context": [
    "https://w3id.org/security/v1",
    {
      "dc": "https://w3id.org/dc/terms/",
      "foaf": "http://xmlns.com/foaf/0.1/"
    }
  ],
  "@id": "http://example.com/logo.jpg",
  "@type": "foaf:Image",
  "dc:title": "Example Logo",
  "digest":
  {
    "@type": "Digest",
    "digestAlgorithm": "http://www.w3.org/2000/09/xmldsig#sha1",
    "digestValue": "981ec496092bf6ea18d6251d36068b52b633268b"
  }
}

To

Example 8

{
  "@context": [
    "https://w3id.org/security/v1",
    {
      "dc": "https://w3id.org/dc/terms/",
      "foaf": "http://xmlns.com/foaf/0.1/"
    }
  ],
  "@id": "http://example.com/logo.jpg",
  "@type": "foaf:Image",
  "dc:title": "Example Logo",
  "digest":
  {
    "@id": "ni://sha-1;981ec496092bf6ea18d6251d36068b52b633268b"
  }
}

And will no longer contain a bnode, and potentially be dereferancable
at /.well-known/ni/sha-1/981ec496092bf6ea18d6251d36068b52b633268b
