/**
 * Represents a catalog of items that are considered as reference data that a
 * user can choose to utilize in various analyzers, transformers etc. All of
 * these implement the {@link ReferenceData} interface.
 *
 * Reference data is typically reusable between jobs which is why it is
 * contained within the configuration. For example you could have a dictionary
 * of valid values for a particular entity type. This dictionary is then
 * reusable both as input to a Dictionary validation filter and an analyzer that
 * will match values against different dictionaries.
 *
 * All reference data types ( {@link Dictionary} , {@link SynonymCatalog},
 * {@link StringPattern} etc.) is injectable into components using
 * the @Configured annotation.
