This study aims to present metadata elements based on the uniqueness of official seals, which are a type of administrative artifact. Official seals guarantee the authenticity of records and serve as administrative artifacts with evidentiary value. However, local governments currently use different sets of metadata elements for managing official seals by institution, and when such seals are transferred to permanent records management institutions, there is a risk of losing vital data. Therefore, metadata elements that reflect the unique characteristics of official seals are necessary. In this study, international metadata standards were examined, metadata elements used for managing official seals in metropolitan governments were investigated and analyzed, and the registration form for administrative artifacts of the National Archives of Korea was referenced to propose metadata elements for the management of official seals. The proposed metadata elements consist of 2 domains—Basic Information and Management Information—with 15 top-level elements and 39 sub-elements, in which mandatory elements are distinguished. Moreover, to reflect the uniqueness of official seals, metadata elements developed in this study were included, such as the Period of Use (Mayor), Seal Creation and Registration Department, Abolition Department, Acquisition Details (Specific Reason, Official Gazette Number, and Legal Basis), Typeface,
Records Management System (RMS) Remarks, Seal-Related Remarks, Seal Creation and Registration Gazette Number, Seal Creation and Registration Public Notice Number, Abolition Gazette Number, and Abolition Public Notice Number.
