+  * `type` - The type of things that the page represents. This must be a [Schema.org type](http://schema.org/docs/schemas.html), and will probably usually be something like [`BlogPosting`](http://schema.org/BlogPosting), [`NewsArticle`](http://schema.org/NewsArticle), [`Person`](http://schema.org/Person), [`Organization`](http://schema.org/Organization), etc.
+  * `links` - An array of other URLs that represent the same thing that this page represents. For instance, Jane's bio page might include links to Jane's GitHub and Twitter profiles.
