026 * Correctness of the explicitly encoded topological characteristics of the data set.
027 * The data set is described by the {@linkplain DataQuality#getScope() scope}.
028 *
029 * <h2>Standardized values</h2>
030 * In order to achieve well defined and comparable quality information, it is recommended to
031 * report data quality using {@linkplain Measure quality measures} listed in ISO 19157 annex.
032 * The following table provides a summary; see ISO 19157 for more complete descriptions and examples.
033 * All identifiers should be in "ISO 19157" namespace.
