public interface MetadataSignatureGenerator

Interface that mark classes that can be used to generate a signature for metadata values. The signature must be a unique identification of a metadata, based on the attributes that compose it (such as field, value and authority). It is possible to generate a signature for a single metadata value and also for a list of values. Given an item, a signature can for example be used to check if the associated metadata is present in the item.
