Most of the framework providers are Nucleus components and can be replaced or extended. Because all providers are registered with the RestResourceRegistry, they can be configured. The default media type support is for the Oracle JSON media type and the HAL media type. You can introduce new media types by creating an additional message body reader and writer. You can create custom lock key provider logic if a resource implements the LockKeyProvider interface. By default the CachePostMatchRequestFilter component is configured with two RestRequestValidator components, one for XSS checks and one for asset locale checks. Additional validators can be configured for any custom request checking that you might need.

Because resources are Nucleus components, you can easily replace or extend them using configuration layering.
