The tag item type enables the creation of labels that can be applied to article and mediaContent items. Aside from its id property, a tag item has only a tag property that holds a simple text string. So, for example, you could create a tag item whose tag property has the value Summer Activities, and apply the tag to articles and media related to summer activities. A single tag can be applied to any number of article and mediaContent items, and a single article or mediaContent item can have any number of tags applied to it. Values of the tag property can be used for searching and guided navigation.
