If you take the idea that articles and comments are actually very similar things, why not simply look at them from a parent/child standpoint.
You have a BlogBO that allows a user to create the initial comment (article or what have you) and allows child comments that are connected to it. Maybe I'm looking at this more from a DB perspective. You can add restrictions (no html, images, etc.) to the child comments within the BlogBO's methods based on whether it's a parent or child comment. This even works with XML as the storage medium. Quick XML structure without bells and whistles: <comment> <guid></guid> <parentguid></parentguid> <datetimestamp></datetimestamp> <title></title> <content></content> <author></author> </comment> parentguid would be 0 for new content or the guid of the comment being replied to (in a messageboard style). datetimestamp allows you to order the comments chronologically. benjamin > I know Scott has decided on a with a solution, but I'd like to > continue this fruitful discussion. > > On Tue, 11 Jan 2005 17:38:41 -0500, [EMAIL PROTECTED] <[EMAIL PROTECTED]> > wrote: > >> It was last night when I realised that there is no real concrete >> relationship between Article and Comment as at the end of the day an >> Article >> can exist without comments > > I'm curious why everyone is asking, "Can an article exist without > comments?"
