P1 Web 2.0 / Web 3.0

There is a lot of talk and writing about web 2.0. Also web 3.0 is already discussed. Perhaps this may be only a hype? What should libraries do in this situation? What does it mean for future research? We would like to open a very wide spectrum of definitions regarding web 2.0 and web 3.0. We also want to discuss examples of services in a library environment. Furthermore metadata and classification are very important issues for both concepts. David Weinberger wrote in his book "Everything Miscellaneous" that classification is outdated, and social tagging will be enough. What does this mean for the libraries? On the other hand, the semantic web (which is one part of web 3.0) can profit from good metadata. What role can librarians play there? And what do they have to learn in future to take part in this development? Artificial intelligence and semantic web techniques might be able to to find and analyse content more easily. Or will this just change the role of information specialists, who are aware of crucial information sources, new developments in information search and retrieval techniques? Is our privacy in danger? According to Hugh Glaser the Semantic web technology can combine multiple pieces of information about persons, places and their activities, e.g. a search engine can provide anyone with your personal profile of interests. Will there be a second digital divide? People are growing dependent on the internet, because more and more real-life activities are done online (like banking, shopping and working). Non-internet users might not be able to operate in the new "online society". Last but not least we would like to discuss the implication of copyright issues. If, like Lawrence Lessig says, there is more and more of a remix culture, what does this mean for the data of libraries? This brings up many other questions, as well. We hope to find answers to some of these questions even if we cannot find solutions for everything.
