My colleague Dean Giustini and I have collaborated on an article, The Semantic Web as a large, searchable catalogue: a librarian’s perspective. In it, we argue that librarians will play a prominent role in Web 3.0. The current Web is disjointed and disorganized, and searching is much like looking for a needle in the haystack.It's not unlike the library before Melvil Dewey introduced the idea of organizing and cataloguing books in a classification system. In many ways, we see the parallels here 130 years later. It's not surprising at all to see the OCLC at the forefront in developing Semantic Web technologies. Many of the same techniques of bibliographic control apply to the possibilities of the Semantic Web. It was the computer scientists and computer engineers who had created Web 1.0 and 2.0, but it will ultimately be individuals from library science and information science who will play a prominent role in the evolution of organizing the messiness into a coherent whole for users. Are we saying that Web 2.0 is irrelevant? Of course not. Web 2.0 is an intermediary stage. Folksonomies, social tagging, wikis, blogs, podcasts, mashups, etc -- all of these things are essential basic building blocks to the Semantic Web.
