Types of Hierarchical Relationships
The defining characteristic of taxonomies is the presence of hierarchical relationships. Information specialists recognize several types of hierarchical relationships. Generic relationship – As explained in ANSI/NISO Z39.19-2005 (page 47), “This relationship identifies the link between a class and its members or species.” The generic relationship is generally called the Broader term/Narrower term relationship. In most cases, it’s easy in traditional biological taxonomy of organisms, because of its well-established and well-known groupings of phyla, genera, families, species, and so forth, i.e., Rodents and NT Squirrels.
