Data owned by another service/application/org that is written and read without modification. For example, a healthcare document that wasn't built or technically owned by the application storing it. For example, a web text editor that serializes it's state as json. Not json, but a web scraper storing html documents. These have structure, it's only that the structure is built/maintained outside of the application storing it. You could of course transform it but I think it's a bit obvious where that might not be worth the cost/complexity.
