A template is a collection of predefined values that users can use to quickly add standard metadata to a resource. Templates enable you to quickly apply standard metadata to resources that have duplicate information, saving you from re-entering the same information for each resource.
Templates can include static information that is the same every time a user applies the template and dynamic information based on replace strings that updates when a user applies the template.
For example, if members of an anthropology department are cataloging images of pottery shards from a site, they can use a template to automatically fill in standard data associated with all of the images including the resource type, format, associated keywords, etc.
