tagged

Tagged is the past participle of the verb tag. It denotes that an item has been labeled or identified with a tag, label, or descriptor. The form is widely used in metadata and annotation to indicate classification or identification.

In social media and photo sharing, “tagged” describes the action of attaching a person or object to content, so others can see who is involved or referenced. Tagging can trigger notifications and aid in organizing posts, photos, and discussions.

In computing and information management, tags are metadata labels used to annotate content. Tags appear in HTML and XML as markup; in software and databases for categorization; and in file managers and photo libraries to label items for easier search and retrieval.

Tagged is also the name of a social networking service that has allowed users to create profiles, connect with others, and share content across web and mobile apps. The service markets itself as a social discovery platform and has faced the typical privacy and moderation considerations associated with online networks.

Together, the term “tagged” covers the general practice of labeling for organization, the user-driven tagging of people and objects in online content, and, as a proper noun, a specific social networking service.
