Schema.org to JSON Schema

Generate JSON Schemas from Schema.org classes

You can find the generated schemas in the schemas/ directory.

To match the JSON-LD approach, properties that accept an array also accept a single value.

Example

Schema.org class for a Book

| Property | Expected Type | Description | | ------------- | -------------- | -------------------------------------------------- | | abridged | Boolean | Indicates whether the book is an abridged edition. | | bookEdition | Text | The edition of the book. | | bookFormat | BookFormatType | The format of the book. | | illustrator | Person | The illustrator of the book. | | isbn | Text | The ISBN of the book. | | numberOfPages | Integer | The number of pages in the book. |

Generated JSON Schema

To do

• Hardcode the identifiers schemas with regular expressions
• Hardcode the inferred property multiplicity after manually checking it
