What Is Web 2.0: Design Patterns and Business Models for the Next Generation of Software
Key words: collective intelligence, rich client, data, software as a service, long tail and beta.

This paper was the first initiative to try to define Web2.0 and understand its implications for the next generation of software, looking at both design patterns and business modes. Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an "architecture of participation," and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.

User Generated Content: Web 2.0 Taking the Video Sector by Storm
Key words: user generated content, information good, communities, markets, audiovisual, film, common good, regulation and intellectual property.

This article examines the communities involved in the distribution and sharing of videos on the internet. Firstly, we study the practices connected with user generated content and describe the appearance of new players (YouTube, Dailymotion, Google Video, Zudeo, etc.) in the audiovisual landscape. We then discuss regulation of the new community model of digital content distribution before moving on to underline the need for the film and audiovisual industries to socially construct new cultural and commercial experiences with film fans.

The Strength of Weak Cooperation: an Attempt to Understand the Meaning of Web 2.0
Key words: Web 2.0, weak cooperation, BarCamp.

This paper examines some continuities and ruptures in the use of Web 2.0 such as blogs, social media, user-generated content services etc. vis-à-vis earlier web services. We hypothesize that one of the sociological characteristics of Web 2.0 services is that making personal production public creates a new articulation between individualism and solidarity, which reveals the strength of weak cooperation. Web 2.0 services allow individual contributors to experience cooperation ex post. The strength of the weak cooperation arises from the fact that it is not necessary for individuals to have an ex ante cooperative action plan or altruistic intention. They discover cooperative opportunities only by making public their individual production. The paper illustrates this phenomenon by analysing the uses of different services and by looking at the new process of innovation that appears through Barcamp and Coworking spaces.

Folksonomy: the New Way to Serendipity
Key words: taxonomy, indexation, innovation and user-created content.

Folksonomy expands the collaborative process by allowing contributors to index content. It rests on three powerful properties: the absence of a prior taxonomy, multi-indexation and the absence of thesaurus. It concerns a more exploratory search than an entry in a search engine. Its original relationship-based structure (the three-way relationship between users, content and tags) means that folksonomy allows various modalities of curious explorations: a cultural exploration and a social exploration. The paper has two goals. Firstly, it tries to draw a general picture of the various folksonomy websites. Secundly, since labelling lacks any standardisation, folksonomies are often under threat of invasion by noise. This paper consequently tries to explore the different possible ways of regulating the self-generated indexation process.

Web 2.0: Nothing Changes…but Everything is Different
Key words: Web 2.0, regulation, law, case law, blogs, liability, intellectual property, personal data, knowledge management, collaborative space and employment law.

For some, Web 2.0 is a "simple" evolution of the current web; for others, Web 2.0 is a real revolution. Web 2.0 is, in fact, a "revolutionary evolution." Technically speaking, Web 2.0 is a "simple" evolution because it is not a technical "breakthrough," as it is essentially based on an aggregation of existing technologies. However, the impact of Web 2.0 is such that it can actually be described as an evolution that will shake our sociological, economic and legal bases. This paper addresses the legal aspects of Web 2.0 and tries to explain that while Web 2.0 is not a lawless domain, it is highly likely to create a legal tsunami.

Product Development 2.0
Key words: web 2.0, user generated, product development and web as a platform.

Web 2.0 principles will not only revolutionize the web experience, the design pattern and the business models of software companies. They can indeed be applied to a lot of industries for new approaches to product development. The web can be used to put users in control and co-create better and richer products in a reduced timeframe.
