RE: Casting literals as IRIs

It seems you have to use the exact term you are using as attribute name in order to coerce it to an @id in the context.
If you use foaf:knows as attribute name, then your context applies. Since you use the full http://xmlns.com/foaf/0.1/knows url as attribute name, you also have to use the full url in the context.

Hm. Interesting. 

Best,

What about this context:

  "@context": {
    "http://xmlns.com/foaf/0.1/knows": { "@type": "@id" }
  }
