extend with own keywords (define a vocabulary)

Provide a service of type io.github.sebastiantoepfer.jsonschema.vocabulary.spi.LazyVocabularies
Provide a implemention of type io.github.sebastiantoepfer.jsonschema.Vocabulary

To use your new Vocabulary put it into the classpath define it in the schema:

{
  $vocabulary: {
    "<id of your vocabulars>": true //or false if is not required -> means validtion works also if it is not in classpath
  }
