嵌套级别重复键的 JSONLD 上下文

问题描述

我将以下 json 与下面的上下文合并，

目前我面临两个问题

1 JSON 中不同级别的重复键或属性如何处理，以便我可以将正确的三元组相互连接？

2 @vocab 被忽略，我在 rowid 上使用了 @id，它在 json-ld 游乐场中添加了一个默认前缀

        {
        "@context": {
            "@vocab": "http://xyz.qte.com/01#","xxx": "http://xyz.qte.com/01#","@base": "http://xyz.qte.com/01#","rowid": "@id","values": "@nest","relation": "@nest","blobs": "@nest","displaytypename": {

                                },{

                            ]
                        }
                    }]
                }

                }
            }


        ]
    }

解决方法

“重复键”是指在 JSON 文档的不同级别用作属性键的相同术语。为此，JSON-LD 具有 Scoped Context 的概念，由此您可以在某些属性的值内或类型有效的地方使用上下文。通过这种方式，例如，您可以定义“值”以映射到顶层的一个 IRI，并在“值”（或一些其他中间属性）的术语定义内，定义一个新的上下文，该上下文重新定义“价值”

关于 @vocab 和 @id，@id 被视为文档相关术语，并且字符串值从文档库或 @base（如果在活动上下文（见section 4.1.3 Base IRI）。 @vocab 用于扩展与词汇相关的术语，例如 @type 和对象属性键，它们没有另外定义为术语（请参阅 section 4.1.2 Default Vocabulary。
