How to know result IRI is literal or named node?

[pheyvaer]

Using the following context and output from the README, how do you if the value of starring in the original data that was queried is a literal or a named node?

{
  "@context": {
    "Film": "http://dbpedia.org/ontology/Film",
    "label": { "@id": "http://www.w3.org/2000/01/rdf-schema#label", "@language": "en" },
    "starring": "http://dbpedia.org/ontology/starring"
  }
}

{
  "data": [
    {
      "id": "http://dbpedia.org/resource/Ocean's_Eleven",
      "starring": "http://dbpedia.org/resource/Brad_Pitt"
    },
    {
      "id": "http://dbpedia.org/resource/The_Favor",
      "starring": "http://dbpedia.org/resource/Brad_Pitt"
    },
    {
      "id": "http://dbpedia.org/resource/The_Assassination_of_Jesse_James_by_the_Coward_Robert_Ford",
      "starring": "http://dbpedia.org/resource/Brad_Pitt"
    },
    {
      "id": "http://dbpedia.org/resource/True_Romance",
      "starring": "http://dbpedia.org/resource/Brad_Pitt"
    },
    ...
  ]
}

It's been a while since I worked on this, but it looks like this tool is hardcoded to materialize RDF/JS terms to strings, so there's no way of distinguishing literals vs IRIs in that case.

You can however pass your own SparqlJsonToTreeConverter into the constructor: https://github.com/rubensworks/GraphQL-LD.js/blob/master/lib/Client.ts#L119
This allows you to set materializeRdfJsTerms to false: https://github.com/rubensworks/sparqljson-to-tree.js#create-a-new-converter

Cool! I will have a look at doing it that way. Thanks!
