126.96.36.199 Social Tags
This protocol enables users to add descriptive keywords to documents and Web pages that were published with a URI. The tags are stored on a back-end database server and are not part of the document or Web page with which they are associated. Each social tag has an identifier, which is retrieved from a term store, and is associated with a URL. Other information that is stored on a back-end database server includes the person who applied the social tag, a flag that specifies whether the tag is visible only to the person who applied the social tag, and the date when the social tag was last modified.
