As luhn said, it’s more about a standard data format than a db choice. If every client has to figure out what schema a website uses for a recipe, let’s say, then Web 3.0 is still unrealistic.

Schema.org exists, but all websites adopting it seems unlikely.

That being said, I can maybe see a world in which one company adopts schema.org schemas and the rest have to follow suit to be competitive in that particular domain.

Schema.org has the backing of major search engines and other reusers of Web-served content. It's way more likely to be adopted compared to anything else in its general domain.
