- mods:geographic = "geographic" is used for geographic subject terms that are not parsed as hierarchical geographics.
- mods:temporal = "temporal" is used for chronological subject terms or temporal coverage. It may be expressed as a controlled subject term or as a structured date using the same data definition as MODS dates.
- mods:titelInfo = "titleInfo" includes a title used as a subject. All subelements and attributes used under the top-level element <titleInfo> may be used with this subelement.

- mods:geographicCode = "geographicCode" includes a geographic area code associated with a resource.
- mods:genre = "genre" includes a genre or form used as part of a subject string when the subject authority distinguishes subdivisions of the main subject (e.g. LCSH). If describing the genre of a resource as a whole, use in the <genre> element.

- In den älteren Goobi-Daten wurde dieses Element häufig für den Autoren-Titel-Schlüssel verwendet.
