Worldwide, hundreds of projects to redesign the Internet are in progress under the banner of the so-called Future Internet. Some argue that the most important thing is to redesign to accommodate information exchanging, a.k.a. information- centrism. Others argue that the most important thing is to redesign to accommodate service-based applications, i.e. service-centrism. Who is right? This paper defends the idea that the most important thing is to redesign to integrate both aspects cohesively — we call this approach Internet of Information and Services (IoIS). Poster at Conference at Future Internet 2012, Seoul, Korea.

IoIS is an integrative approach for combining information-centrism, service-centrism,
publish/subscribe paradigm, name-based binding, searching and discovery, and distributed
hash tables in an unique architecture.
It is the core of a broad architecture called NovaGenesis.
