public class WriteMethodsForChroniclesAndSeries
extends ReadMethodsForChroniclesAndSeries

A stateless object with methods providing write access to chronicles and series. To keep things as simple as possible in a first version, chronicles and series values are stored separately, as in relational implementations. Changing this would require a non-negligible part of the implementation.
