Tags are a special type of keyword that you can associate with content records to searches that are more powerful and the automatic population of content based on tags. All descendants of a content folder inherit the tags defined for the folder. You can tell which tags are being inherited from a content folder higher in the content folder hierarchy by viewing the Current Tags section of a content folder's or content record's definition.
■ AdvancedSearch iParts specify various tags that your CM website users can select to narrow their search to a smaller set of tagged content records.
■ ContentTaggedList iParts specify various tags that are used to generate a real-time list of links to tagged content records when the content record containing the ContentTaggedList is viewed.
Tagged list formats are used by ContentTaggedList iParts to format the rendered display of the list of links. The chosen tagged list format is applied as a display mask to each item in the list. For example, one tagged list format might display only a simple list of links, while another tagged list format might display a link followed by an HTML fragment from the target content record.
Unlike some other content authoring systems and web applications, you cannot create ad hoc tags while defining content records. Instead, you must choose from a list of pre-defined tags (that are usually defined by the people who perform website management). This restriction ensures that your content is tagged with a centrally designed taxonomy, which provides more consistent and predictable search results from ContentTaggedList iParts.
Tags are defined in a hierarchical structure, with every parent tag having an implicit more broadly defines relationship to its children tags, and every child tag having an implicit further defines relationship to its parent tag. In general, this means that if you use a parent tag in an AdvancedSearch or ContentTaggedList iPart, all descendant tags are automatically included as well.
