EXERCISE 8.3: DATA PORTABILITY, FOAF AND THE SEMANTIC WEB
The Semantic Web is an enhancement that gives the Web greater utility. The Friend of a Friend (FOAF) project, is a social-networking system where users post information and imagery in any format they like and still connect it all, which other social networks like MySpace and Facebook cannot do because of incompatible data language. The Semantic Wed uses a data language, "called Resource Description Framework (RDF), which names each item, and the relations among the items, in a way that allows computers and software to automatically interchange the information." (L.Feigenbaum et.al.)
Some "observers worry that people's privacy could become compromised as more data about them from different sources is interlinked. Advocates argue that the protections are the same as those used in the non linked world. If two databases joined by the Semantic Web have different privacy criteria, then the software will have to honor both sets of rules or create a set that covers both".(L.Feigenbaum et.al.)
FOAF is written in OWL or Web Ontology Language which allows users to choose the "sites and tools they like without being cut off from their friends". This is great as it allows users of mac and windows to get together.
