Create concept of PublishedEvent

[pilloPl]

So currently the all of the domain events have information about business facts.

If we want to publish them we need to add metadata like:

causationID,
corellationID,
uniqueMessageID
etc

so PublishedEvent becomes DomainEvent + metadata

So, if I understand correctly, do you mean that

public interface EventsStorage {

    void save(DomainEvent event);

    List<DomainEvent> toPublish();

    void published(List<DomainEvent> events);
}

should be more like

public interface EventsStorage {

    void save(DomainEvent event);

    List<DomainEvent> toPublish();

    void published(List<PublishedEvent> events);
}

I mean that PublishedEvent should keep DomainEvent inside :)
