Best JSON-LD practices: using multiple <script> elements?
提问by Stu Furlong
I'm curious about the best practice for applying JSON-LD onto a site for schema.org.
我很好奇将 JSON-LD 应用到 schema.org 站点的最佳实践。
If I have a page with an Articleand I also want to define WebSiteon my page, I would have this:
如果我有一个带有 的页面Article并且我也想WebSite在我的页面上定义，我会有这个：
<script type="application/ld+json">
{
"@context": "http://schema.org",
"@type": "WebSite",
"url": "http://www.example.com/",
"potentialAction": {
"@type": "SearchAction",
"target": "http://www.example.com/search?&q={query}",
"query-input": "required"
}
}
</script>
<!- … -->
<script type="application/ld+json">
{
"@context": "http://schema.org",
"@type": "Article",
"author": "John Doe",
"interactionCount": [
"UserTweets:1203",
"UserComments:78"
],
"name": "How to Tie a Reef Knot"
}
</script>
Is this correct or wrong? Is there any benefit or need to merge these into the same script or array of items?
这是正确的还是错误的？是否有任何好处或需要将它们合并到相同的脚本或项目数组中？

It's valid. You can have as many data blocks (= scriptelements) as you wish.
这是有效的。您可以根据需要拥有任意数量的数据块（=script元素）。
A possible benefit of using only one scriptelement: it allows to make relationships between multiple items easier (e.g., should you decide to use hasPartor mainEntity), as you simply have to nest the items.
But making these relationships is of course also possible when using separate data blocks, by referencing the URI of the item with @id(thanks, @ Gregg Kellogg).
只使用一个script元素的一个可能的好处：它允许使多个项目之间的关系更容易（例如，如果您决定使用hasPart或mainEntity），因为您只需嵌套这些项目。
但是，在使用单独的数据块时，当然也可以通过使用@id(谢谢，@ Gregg Kellogg)引用项目的 URI 来建立这些关系。
(For reference, adding two or more top-level items in a single scriptis possible with @graph.)
（作为参考，在一个单一的添加两种以上顶级项目script是可能的@graph。）

There is no benefit in having single or multiple data blocks, other than limitations around how you might store and manage schema data in your website.
除了限制您在网站中存储和管理架构数据的方式之外，拥有单个或多个数据块没有任何好处。
For example, you might need them separate if different components within your website are responsible for generating each data block independently. Alternatively, if your website is able to manage all schemas for one page in one place, it may be simpler to manage a single data block and render this as a single scriptelement.
例如，如果您网站中的不同组件负责独立生成每个数据块，您可能需要将它们分开。或者，如果您的网站能够在一个地方管理一个页面的所有架构，那么管理单个数据块并将其呈现为单个script元素可能会更简单。
You can combine these into a single script by listing each schema as an array like this:
您可以通过将每个模式列为一个数组来将它们组合成一个脚本，如下所示：
<script type="application/ld+json">
[
{
"@context": "http://schema.org",
"@type": "WebSite",
"url": "http://www.example.com/",
"potentialAction": {
"@type": "SearchAction",
"target": "http://www.example.com/search?&q={query}",
"query-input": "required"
}
},
{
"@context": "http://schema.org",
"@type": "Article",
"author": "John Doe",
"interactionCount": [
"UserTweets:1203",
"UserComments:78"
],
"name": "How to Tie a Reef Knot"
}
]
</script>
