如何修正JSON-LD语法以实现预期的属性值展开效果？

要实现仅指定属性值的URI展开，同时避免属性名和类型被错误扩展，只需调整@context的配置，无需使用@vocab：

正确的JSON-LD代码 #

{
  "@context": {   
    "number": "locator:requirements/number/",
    "var": "locator:models/",
    "operator": {"@container": "@list"},
    "target": {"@container": "@list"},
    "variable": {"@container": "@list"}
  },

  "@graph": [
    {
      "@id": "number:001",
      "target": {
        "@type": "float",
        "@value": 22.6
      },
      "variable": {
        "@id": "var:StarTracker/AngleToSun"
      },
      "operator": "minimum"
    }
  ]
}

配置说明 #

1. 前缀映射：仅在@context中定义number和var两个前缀，确保只有使用这些前缀的@id值会被展开为完整URI（比如number:001→locator:requirements/number/001，var:StarTracker/AngleToSun→locator:models/StarTracker/AngleToSun）。
2. 容器配置：为operator、target、variable添加"@container": "@list"，强制这些属性的展开结果以数组形式呈现，完全匹配你期望的输出结构。
3. 避免全局扩展：不设置@vocab，这样operator、target等属性名以及float类型都不会被错误扩展，保持原样。

展开后的结果 #

[
  {
    "@id": "locator:requirements/number/001",
    "operator": [
      {
        "@value": "minimum"
      }
    ],
    "target": [
      {
        "@type": "float",
        "@value": 22.6
      }
    ],
    "variable": [
      {
        "@id": "locator:models/StarTracker/AngleToSun"
      }
    ]
  }
]
