There are an infinite number of variations for the JSON-LD “Person” type so we did our best to include some of the more popular properties.
Here is another JSON-LD example I found courtesy of Jay Holtslander. You can check out his repo here which has some more awesome examples of JSON-LD types.
As with any type of structured data, there are no guaranteed results. If you are dedicated in your efforts and have a good amount of authority Google may produce a Knowledge panel.
Google retrieves answer boxes and featured snippets from a variety of sources including websites with structured (and unstructured) data, Wikipedia, Wikidata, Freebase and a number of other public data sources.
There are other results that may or may not be produced as a result of JSON-LD schema markup for a person such as a person’s height, birthday, place of birth, and much more.
