Trackback and Pingback for inferring metadata

They are two similar technologies (protocols) to exchange links between blogs or weblogs. Trackback is much more RDF oriented while Pingback XML oriented and of course I like more the former :-)

There is a lot of discussion going on about the argument here and here. A comparinson of the two protocols is available here.

I think such "hyperping-ing" (hyperlinking? :-) technology could help the growth of the Semantic Web e.g. try to imagine that while weblog authors or bloggers exchange links to be displayed on their nice Web sites, at the same time they would be also exchanging metadata for free :-)

This is much in line with Stefano Mazzocchi presentation (you need RealOne player) about "automatically inferring" metadata and links between web resources, like Google, Amazon or CiteSeer are doing.
