控制RDF到“更漂亮”的JSON-LD的转换

我知道从RDF到JSON-LD的转换有一些限制，但是我想知道是否存在一种使转换避免使用空白节点的好方法？

例如，给定一个RDF图：

@prefix ex: <http://example.org/ontology#> .
<http://example.org/x123> ex:house [
                                      a ex:House ;
                                      ex:houseNumber "1a" ;
                                      ex:doorColour "blue"
                                   ] ;
                          ex:house [
                                      a ex:House ;
                                      ex:houseNumber "1b" ;
                                      ex:doorColour "green"
                                   ] .

是否可以使用（Java）JSON-LD强制转换为bnode的基于数组的表示形式：

{
  "id": "http://example.org/x123",
  "house": [{
    "type": "House",
    "houseNumber": "1a",
    "doorColour": "blue"
  }, {
    "type": "House",
    "houseNumber": "1b",
    "doorColour": "green"
  }],
  "@context": {
      "ex": "http://example.org/ontology#",
      "house": "ex:house",
      "houseNumber": "ex:houseNumber",
      "doorColour": "ex:doorColour",
      "House": "ex:House",
      "id": "@id",
      "type": "@type"
  }
}

而不是这样的：

{
  "@graph": [
    {
      "@id": "_:b0",
      "@type": "http://example.org/ontology#House",
      "http://example.org/ontology#doorColour": "blue",
      "http://example.org/ontology#houseNumber": "1a"
    },
    {
      "@id": "_:b1",
      "@type": "http://example.org/ontology#House",
      "http://example.org/ontology#doorColour": "green",
      "http://example.org/ontology#houseNumber": "1b"
    },
    {
      "@id": "http://example.org/x123",
      "http://example.org/ontology#house": [
        {
          "@id": "_:b0"
        },
        {
          "@id": "_:b1"
        }
      ]
    }
  ]
}

目前，我正在遍历图中的语句并手动生成JSON，但是是否可以使用java-jsonld之类的库或其他JSON-LD技术来做到这一点？
