Question:

Can I just use data.get('?s').id?

Where can I found a document, I've searched through http://rdf.js.org/#source-interface but still don't know where to look at...

All result bindings are RDFJS terms according to this spec: http://rdf.js.org/data-model-spec/

The raw value will typically be retrievable using .value. Definitely do not use .id, as this is an internal field of N3.js, which will not be available if you use different parsers/stores.

Thanks for the explanation.

I tried to log it out:

result.bindingsStream.on('data', data => {
  console.log(data.get('?s'), data.get('?p'), data.get('?o'));
});

got

Object { id: "null" }
Object { id: "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" }
Object { id: "http://www.w3.org/ns/ldp#BasicContainer" }

Object { id: "null" }
Object { id: "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" }
Object { id: "http://www.w3.org/ns/ldp#Container" }

So I was confused.

So what returned from data.get('?s') is a http://rdf.js.org/data-model-spec/#variable-interface right?

No, this will actually never be Variable. This will either be NamedNode, Literal or BlankNode, depending on the types of RDF terms that you are querying.
