/**
 * Identifies a {@link Repository}. Repositories simulate a collection of aggregates to which aggregate instances can be
 * added and removed. They usually also expose API to select a subset of aggregates matching certain criteria. Access to
 * projections of an aggregate might be provided as well but also via a dedicated separate abstraction.
 * 
 * Implementations use a dedicated persistence mechanism appropriate to the data structure and query requirements at
 * hand. However, they should make sure that no persistence mechanism specific APIs leak into client code.
