Re: writing from Model to JSON-LD without a base

[Erich Bremer]

 @prefix schema: <http://schema.org/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

<http://njh.me/>
  a schema:CreativeWork ;
  schema:description "An impressive description"^^xsd:string ;
  schema:name "This is an example of JSONLD"^^xsd:string .

so, in imaginary code, I need something like this for the TTL:

    RDFWriter.create()
    .swapbase("http://njh.me/";, "./")      // <------ Valid URI.
    .lang(Lang.JSONLD)
    .source(m)
    .output(System.out);

to get:
{
"@context": [
"https://schema.org/";
],
"@graph": [
{
"@type": "CreativeWork",
"description": "An impressive description",
"name": "This is an example of JSONLD",
"@id": "./"
}
]
}
