What defines a "use reference" in taxonomy?

A "use reference" in taxonomy is defined as a term that is synonymous with another term. This function is essential in classification systems, as it helps clarify relationships between terms and ensures consistency within the taxonomy. By indicating that one term is synonymous with another, it aids users in understanding that they can interchange the terms without losing meaning. This is particularly useful in navigating complex taxonomies where different terminologies may be used to describe the same concept, allowing for more efficient and accurate data retrieval.

Other aspects related to taxonomy include how terms can have broader meanings or delineate specific groups of services; however, these characteristics do not directly pertain to the definition of a "use reference." Instead, a "use reference" specifically denotes synonymy, focusing on the interchangeability of terms to promote clarity and accessibility within taxonomical frameworks.
