Flickr
Social Media Platform
Flickr is primarily a photo hosting Web site, web services suite, and online community platform. While most users share personal photographs, the service is also widely used by bloggers as a photo repository.
Photo submitters use tags to organize images, which allow them to find images related to particular topics, such as place names or subject matter.
While most photos are copyright protected, with permission, friends, family, and other contacts can organize, add comments, notes and tags, which are also searchable.
Flickr allows users to organize their photos into "sets", or groups of photos that fall under the same heading. These "sets", then, represent a form of categorical metadata rather than a physical hierarchy. Sets may be grouped into "collections", and collections further grouped into higher-order collections.
