Extending item with backlink to parent item
- My suggestion is to extend the <source> of an <item> so that it
points to the exact item inside the source feed. Then a viewer can
download the feed, find the parent item and display the item in a
broader context, like tree of items.
I think the best way to do it would be in a permalink, then it could
also integrate with the Pingback/TrackBack techniques to signal an
item on a weblog that someone else has linked to it.
I don't know the best way to add the needed information, I don't have
that much experience writing specs, perhaps the source element of the
Dublin Core could be used here?
