Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, and this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an interesting and valuable service, particularly important as social networks are often being formed through created content and things that people have in common (“object-centred sociality”). SIOC is a Semantic Web research project that aims to describe online communities on the Social Web. This paper describes how SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites, and introduces a SIOC Types module to further specify the type of content items and act as a “glue” between user posts and the content items created and annotated by users.

Prosuming is one of the magic activities of the Web 2.0. The idea that media con- sumers can become media producers has been validated with all its pros and cons in systems like YouTube and Flickr.com.

Especially, making movies was thought to be an area where only teams of highly specialized experts equipped with a lot of money can produce high quality movies with a world-wide audience. But next to Hollywood other production centers emerged like ”Bollywood” in India or ”Nollywood” in Nigeria with local practices. YouTube has proven that amateurishly produced content can fascinate people on the Internet.

“The right to privacy” was the title of a scholarly article in the Harvard Law Review of 1890 (written by Samuel Warren and Louis Brandeis), which proclaimed such a right in view of the rapid expansion of print media that sometimes published pictures of private individuals.

The mercurial rise of social networking sites and user-generated content has rekindled users’ interest in accessing Web-based services on the move. That the mobile phone is an inherently personal device which is not only with us most of the time, but also contains a huge amount of personal data (contact lists of names and phone numbers, stored messages and emails etc.) makes it a logical extension for the social network and the host of other collaborative Web 2.0 applications gaining traction.
