030 * Information about the reliability of data quality results.
031 * The knowledge about the suitability of the quality evaluation method
032 * may be of the same importance as the result itself.
033 * Instances should be one of the following subtypes:
034 * <ul>
035 *   <li>{@link Confidence}: trustworthiness of a data quality result;</li>
036 *   <li>{@link Representativity}: degree to which the sample used has produced
037 *       a result which is representative of the data within the data quality scope;</li>
038 *   <li>{@link Homogeneity}: expected or tested uniformity of the results obtained for a data quality evaluation.</li>
