124 Personal Content Experience: Managing Digital Life in the Mobile Age group members they were able to order the material of the rowdy night into some sensible order. Too bad that the automatically generated links between text messages, blog entries, and e-mails made almost no sense. For instance, what did “Cowbells ringing in my head” have in common with “Chocolate”? After consulting with the university researchers, Bob realized that they were lacking the proper vocabulary. They linked the material to the proper ontologies on hiking, the Alps, mountain fl ora, orienteering, and the like. Some of the ontologies lacked French versions, so they had to resort to another step of automatic translation between the defi ni- tions. Bob then ran the association discovery again, and the result was far better. Not perfect but already usable. To his surprise even the pictures of the signposts now turned up in right places on the map. After a few nights polishing, Bob released the full material on the group site. He asked the people to repair any obvious blunders, and the cell jointly arrived at a useful version within a week. They then arranged a “Retour a Chamonix” night to celebrate the experience, this time with Ritchie joining the fun. They wisely had decided to skip the raclette this time to leave more room for the wine, which seemed to be an essential part of the Chamonix re-experience. Bob, Trisha, and Gerry all presented their favourites of the hypermedia shows that Experience Engine had automatically compiled. The group agreed that the presentations were somehow strange, with unlikely structure, but still quite amusing and refreshingly different to standard slideshows. They decided to use the same recording setup in their next upcoming demonstration in Milan next December. Functionality related to standardized metadata is a central part of applications and services as it facilitates basic functionality for personal content management with operations such as comparing, organizing, searching, and browsing. In essence, (smart) metadata is not only plain text or thumbnail images, but links to other objects that are related in some way. The relations and associations facilitate the dawn of new applications, ser- vices, and content types that work seamlessly together. As part of the interworking, the applications and services can access any objects and they are always up-to-date and synchronized as the low-priority pro- cesses are performed, for instance, when the device is in an idle state in the background. 4.11 References Aaltonen A., Huuskonen P., and Lehikoinen J.
