在 JSON-LD 标记模式中实现“@graph”关键字

Question

下面代码中“@graph”关键字的应用是否正确？ 我在这里试图做的是建立产品“钢丝绳”和钢丝绳类型之间的关系。 我还想将产品组“钢丝绳”表示为产品类型的架构。 因此，“@graph”属性。 我的代码正确吗？

Answer 1

图表中的最后一个逗号位置错误。尝试一下

"@graph": {
    "@type": "Product",
    "name": "Wire Rope",
    "aggregateRating": {
        "@type": "AggregateRating",
        "ratingValue": "4.9",
        "reviewCount": "19"
    }
},

您想通过使用图表实现什么目标？
