All Superinterfaces:

Registry<Metadata,MetadataKey>

public interface MetadataRegistry
extends Registry<Metadata,MetadataKey>

The MetadataRegistry is the central place, where additional information about items is kept. Metadata can be supplied by MetadataProviders, which can provision them from any source they like and also dynamically remove or add data.
