-Commentary,"This field is the second-most prominent value (after [Title](../ogm-aardvark/#title)) that users see when search or browsing for items. Although not required, it is strongly recommended. If the description is minimal or lacking, it can be improved by concatenating available metadata fields, such as title, date, format, and place. This is a plain text field by default, but it can include clickable links if the GeoBlacklight software is customized; see the [GeoBlacklight documentation](https://geoblacklight.org/docs/rendering_html_from_description/) on how to render HTML from a text field."
