You can create a custom Adobe Experience Manager (AEM) HTL (formally Sightly) component that searches for AEM content tags. Tags are a quick and easy method of classifying content within your website. In technical terms, a tag is a piece of metadata assigned to a content node within AEM (usually a page). A custom tag library uses an OSGi component. Within the OSGi component, the AEM Tag Manager is used to search for the content tags, For information about the API, see TagManager API.
After you develop the AEM HTL component, you can invoke its actions from an AEM component. For example, the component can display information about a content tag, as shown in the following illustration.
