Figure 1: Attributes of the UserComments class.

The UserComments class provides five attributes for modeling user-submitted comments: commentText, commentTime, creator, discusses, and replyToUrl. The commentText attribute is used to indicate the text of the comment. The commentTime attribute is used to indicate the time at which the comment was submitted. If your site provides a URL at which users may post additional comments or to respond to specific comments, this URL may be indicated with the replyToUrl. The authorship of UserComments objects is indicated via the creator property. The discusses property provides a relationship back to the NewsItem being commented on.
