You can instantly load all JSON schema files from schemastore.org in JSONBuddy. All you need to do is to use the "File | Open from JSON schema library..." command to show the open dialog which reads all available schema documents from the public schema store. This list is updated from schemastore.org everytime you start JSONBuddy.
Open JSON schema from library dialog
schemastore.org is a great resource to learn how others are writing JSON schemas and can help a lot on providing own specifications for your JSON data. After the schema is loaded in JSONBuddy, the editor will automatically generate JSON sample data. You can immediately create a new document from the sample data using the "JSON | Generate sample document from JSON schema" command.
In addition, the unique built-in JSON schema analyzer will start to report any issues it can find about the schema.
