嵌套级别重复键的 JSONLD 上下文

Question

我将以下内容 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 playground

中添加了默认前缀

        {
        "@context": {
            "@vocab": "http://xyz.qte.com/01#",
            "xxx": "http://xyz.qte.com/01#",
            "@base": "http://xyz.qte.com/01#",

“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 有一个 Scoped Context 的概念，因此您可以在某些属性的值或类型生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”的术语定义（或其他一些干预属性）中，定义一个新的上下文，它重新定义“值”的映射

关于 @vocab 和 @id，@id 被认为是文档相关术语，字符串值从文档库扩展，或者 @base，如果定义在活动上下文中（参见 section 4.1.3 Base IRI). @vocab is used for expanding vocabulary-relative term such as @type and object property keys, which aren't otherwise defined as terms (see section 4.1.2 Default Vocabulary.
