Turning simple JSON-LD into mangle facts?

[burakemir]

People claim that the meaning of JSON-LD is RDF.

Let's look at this friend-of-a-friend example.

{
  "@context": {
    "name": "http://xmlns.com/foaf/0.1/name",
    "homepage": {
      "@id": "http://xmlns.com/foaf/0.1/workplaceHomepage",
      "@type": "@id"
    },
    "Person": "http://xmlns.com/foaf/0.1/Person"
  },
  "@id": "https://me.example.com",
  "@type": "Person",
  "name": "John Smith",
  "homepage": "https://www.example.com/"
}

I'd rather do someting like this, and in Mangle I can:

foaf_person(/me.example.com).
foaf_name(/me.example.com, "John Smith").
foaf_workplace_homepage(/me.example.com, "https://www.example.com/").

It is clear that somewhere, we'd have to remember that predicate foaf_name is really "http://xmlns.com/foaf/0.1/name" etc.

I am wondering if one could come up with a full mapping (turning lists to lists, and using multiple facts for sets).

Just FYI to anyone ever seeing this, I intend to explore doing (something like) this in enola-dev/enola#842...
