News headlines and news stories
A news headline is a relatively short message containing free text, with a link to the more detailed news story behind the headline, and a date. The story link can be in any format; for example, it could be a link to a news story object (see below), or a URL pointing to an external web page. A headline can also have tags (or codes) associated with it, that you can use in searches.
A news story is an arbitrary length text item, referred to by one or more news headlines.
