Use this relationship as a planning aid before writing JSON-LD.
Example shown — validate finished markup with Google’s Rich Results Test.
How it works
- Enter the main structured-data entity.
- Add a connected entity and the property that joins them.
- Use the visual map as a guide when building JSON-LD.
A relationship maps a property on one entity to another entity. For example, a LocalBusiness can use its address property to reference a PostalAddress.
FAQ
Does this generate valid JSON-LD?
It visualizes a planned relationship. Use Schema.org documentation and a validator before publishing markup.
Which entities can I use?
Enter any Schema.org type and property you want to plan.
Is this a replacement for testing?
No. It helps communicate the structure; test final markup separately.
