new cases for distributed XML data

1. the idea of social networks devised a project named FOAF (Friend of a Friend). The concept here is that the owner of the data (that's you) creates one XML file containing your acquaintances (the info in 'Infoware') and distribute that as you like.
2. Another XML file based project I've been following is DOAP. Edd Dumbill wanted to apply the same idea as FOAF to Description of a Project. This is an XML file that contains all the info you'd ever want to know about a software project in one place that doesn't require being duplicated by hand in the handful of open source project sites.
3. Geocaching is an entertaining adventure game for gps users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a gps unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet. GPS users can then use the location coordinates to find the caches. Once found, a cache may provide the visitor with a wide variety of rewards.
