We examined how data provenance and additional information of element values including nomens, and administrative information on the metadata should be modeled and represented in the Resource Description Framework (RDF) for linked data of library catalogs. First, we classified such information types into categories and organized the combination with recording-units, i.e., a description statement or description set. Next, we listed the appropriate RDF representation patterns for each recording-unit. Then, we reviewed the methods to examine such information in Resource Description and Access (RDA) in RDF, BIBFRAME, and Wikidata, and pointed out the issues involved in them.
