Re: Providing the @type in the @context for a value

Hello Robert,

Thank you for confirming what I suspected.

However, as I understand it, doing this is possible using
https://www.w3.org/TR/json-ld11-framing

But, it is unclear what my frame should look like.

Ideally, I would like to be able to start with:

{
     "@context": {
        "ex": "http://example.com/",
        "yyyy": "ex:yyyy",
        "name": "ex:name",
        "rdf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#",
        "rdfs": "http://www.w3.org/2000/01/rdf-schema#",
        "sch": "http://schema.org/",
        "xml": "http://www.w3.org/XML/1998/namespace",
        "xsd": "http://www.w3.org/2001/XMLSchema#"
    },
    "yyyy": {
        "name": "my name"
    }
}

and end up with the desired result. I just need two "@types" inserted in
this simple example.

If anyone can provide any assistance, it would be appreciated as I continue
to read about framing.

Regards,
James
