JSON中的Schema.org isConsumableFor属性

Question

尝试整理如何在JSON中使用isConsumableFor属性schema.org。我把主要产品设置为“覆盆子Pi 4”和isConsumableFor产品“电源”。

JSON片段是为"Raspberry Pi 4“构建的：

{
    "@context":"http://schema.org/",
    "@type":"Product",
    "name":"Raspberry Pi 4",
    "image":[
        "raspberry-pi-4-model-b.jpg",
        "raspberry-pi-4-model-b-2.jpg",
    ],
    "description":"Raspberry Pi 4 ...",
    "offers":{
        "@type":"AggregateOffer",
        "offerCount":1,
        "highPrice":"40.00 ",
        "lowPrice":"40.00 ",
        "priceCurrency":"EUR",
        "offers":[
            {
                "@type":"Offer",
                "priceCurrency":"EUR",
                "priceValidUntil":"2019-11-09T21:50:32+01:00",
                "url":"Raspberry-Pi-4-Model-B",
                "price":"40.00 ",
                "itemCondition":"http://schema.org/New",
                "availability":"http://schema.org/InStock",
            }
        ]
    }
}

在Raspberry Pi 4的页面上，我要在哪里启动属性"isConsumableFor"？？去树莓Pi 4还是电源？

{
    "@context": "http://schema.org/",
    "@type": "Product",
    "isConsumableFor":{ 
        "@context":"http://schema.org/",
        "@type":"Product",
        "name":"Raspberry Pi 4",
        "url":"example.com",
    },
}

或者这样做，但如果有更多的消费品可供Raspberry Pi 4比它将重复所有时间的覆盆子Pi 4，其中一次应该是足够的所有配件：

{
    "@context":"http://schema.org/",
    "@type":"Product",
    "name":"Power Supply",
    "image":[
        "psu.jpg",
        "psu-2.jpg",
    ],
    "description":"Power Supply ...",
    "offers":{
        "@type":"AggregateOffer",
        "offerCount":1,
        "highPrice":"8.00 ",
        "lowPrice":"8.00 ",
        "priceCurrency":"EUR",
        "offers":[
            {
                "@type":"Offer",
                "priceCurrency":"EUR",
                "priceValidUntil":"2019-11-09T21:50:32+01:00",
                "url":"powersupply",
                "price":"8.00 ",
                "itemCondition":"http://schema.org/New",
                "availability":"http://schema.org/InStock",
            }
        ]
    },
    "isConsumableFor":{ 
        "@context":"http://schema.org/",
        "@type":"Product",
        "name":"Raspberry Pi 4",
    }
}

将您的JSON修改到下面将使其对结构化数据测试工具有效，但是这种方法有几个注意事项，这取决于您如何生成内容。

我认为最好的方法是利用全局标识符(id)：

覆盆子Pi

{
    "@context":"http://schema.org/",
    "@type":"Product",
    "id":"https://example.com/raspberrypi4",
    "name":"Raspberry Pi 4",
    "price":"49"
    ...
}

电源

{
    "@context":"http://schema.org/",
    "@type":"Product",
    "name":"Power Supply",
    "image":[
        "psu.jpg",
        "psu-2.jpg"
    ],
    "description":"Power Supply ...",
    "offers":{
        "@type":"AggregateOffer",
        "offerCount":1,
        "highPrice":"8.00 ",
        "lowPrice":"8.00 ",
        "priceCurrency":"EUR",
        "offers":[
            {
                "@type":"Offer",
                "priceCurrency":"EUR",
                "priceValidUntil":"2019-11-09T21:50:32+01:00",
                "url":"powersupply",
                "price":"8.00 ",
                "itemCondition":"http://schema.org/New",
                "availability":"http://schema.org/InStock"
            }
        ]
    },
    "isConsumableFor":{ 
        "@type":"Product",
        "name":"Raspberry Pi 4",
        "id":"https://example.com/raspberrypi4",
        "offers":[{
            "@type":"Offer",
            "price":"49"
        }]
    }
}

正如您所看到的，因为isConsumableFor需要一个Product ( Product仍然需要offers、Review或aggregateRating )，所以您至少需要提供其中一个属性(在本例中，我在price中使用Offer )。

不幸的是，isConsumableFor并不是很好的文档化的论schema.org --在本文撰写之时--这个问题实际上在该属性的前四名Google结果中。

就我个人而言，我觉得嵌套的Offer/aggregateRating/Review.需要一个id或url应该可以满足对Product的要求。我认为这是因为Schema一直在增长。

尽管如此，更大的问题可能是--您使用这个架构是为了什么？如果你想用它来改进谷歌的结果--我个人认为无论你如何使用它，你都找不到多少好处。如果您试图通过JSON通过另一个系统连接您的数据，那么我不会太认真地对待结构化数据测试工具。
