Hypertext address for net News

The format of a hypertext reference to information in the internet/usenetnews system can take any of the following forms:

news: newsgroup: This refers to a list of articles currently availablein the given newsgroup. The newsgroup is a series of alphanumericcharacters and dots.
news:*: This refers to a list of valid newsgroups.
news: message_id: This refers to a given article explicitly. The message_idis optionally surrounded by angle brackets, and must contain an @sign.

Possible extensions to this are more generous wildcarding for thelist of newsgroups. It takes too long to load the whole list, andit would be more useful to be able to browse through a set of newsgroups.

There is no way of referring to 'unread' articles. Keeping track ofthis is the job of the browser.

Examples

news:<12345678@cernvax.cern.ch> news:12345678@cernvax.cern.ch</12345678@cernvax.cern.ch>These addresses both refer to the same (imaginary!) article by itsunique message-id. (Note the hostname in the message-id is just partof the message id generated by the sender of the message - it is nota news server address). news:comp.sys.next.announceThis refers to a list of articles in the newsgroup comp.sys.next.announce.The list is, of course, a list of references to article by message-id.
