Udell presents the Personal Service-Oriented Architecture
Jon Udell discusses Your Personal Service-Oriented Architecture (SOA), which lays out the elements of the futuristic Apple Knowledge Navigator are actually available today, but with out the voice interaction. Jon points out that we already use search much like the navigator, but we are missing the ability to keep track of what we found valuable or not valuable from those searches that are related to similar searches the use ran in the past.
I really like this idea one's own Web browser will show you links you have followed before (within a limited amount of time), but these visited links and the metadata we add to this information does not easily transcend machines. I work on three or four machines through out a normal day as well as a few mobile devices. Each machine has bits and pieces of information strewn across them, but with only a little bit of it synched. This I would love to have worked out in the not so distant future. It takes some effort to get the information synching between the machines and devices (part of the Personal Info Cloud).
There are many gems in Jon's short article, including sharing information and searches with friends or "buddies".
