Eighth example: augmenting schemas with custom format attributes

link to schema

This example adds a custom format attribute named uuid, which checks whether a string instance is a valid UUID.

For this, you need to write an implementation of FormatAttribute, registering it in a Library, and feed that library to a ValidationConfiguration which you submit to the JsonSchemaFactory.

Here, we choose to augment the draft v4 library, which we get hold of using DraftV4Library.get(); we thaw it, add the new attribute and freeze it again. We also choose to make this new library the default by using ValidationConfigurationBuilder.setDefaultLibrary(String, Library).

Note also that the schema has no $schema defined; as a result, the default library is used (it is not recommended to omit $schema in your schemas, however).

Two sample files are given: the first (link) is valid, the other (link) isn't (the provided id for the second array element is invalid).
